Did you have voltage on the connector to the fan? I have ground and voltage and continuity in my signal wire and I even replaced the fan but it’s still not activating
There could be the passage of voltage, but relay it self failing, and it's dirt cheap, so i would replace it anyway, there nothing else in between of the fan and DME, only relay! There little connect that comming from DME, if you replace relay and it still not working, there could be a problem in the wiring or connector itself, but like i said, replace the relay first, then go from there!
It's should be there, also it's really easy to see it from under the hood, just see where the positive/Red cable from fan going, and it will get you to relay!
Great, your video will be very useful to me. I have code 2EFE and the fan turns on but it blows when I turn on the air conditioning and it has to turn on at high volume.
Hey bro, I have a 328i conv The fan turns on when the car runs and turns off only when the car turns off the temperature marks up to 110 on the dashboard
in your car you have the radiator fan switch instead relay, so make sure it's working correctly! also if the car in the limp mode or it's running lean it can case that problem? do you have any massages?
I have same problem I have bmw 125i f20 with n20 engine had 1d2404 map thermostat control line break and cooling fan running on high speed changed thermostat error is gonne but still even now my cooling fan goes on not on full speed but does spin is this normal? I dont think so because I only driven for 2 miles and fan started to spin when I open bonnet and check as I cannot hear it when in car , I have bought fan relay from BMW will be changing that tomorrow did you find the issue ???? Or any tips what to check ?
I have 2008 bmw 328i e92 Coupé with n52 motor my radiator fan only twitches in idle but runs okay with a/c on not sure what the issues is I changed thermostat,coolant flush ,new resivoir , new radiator not sure what it could be or if I just need a new fan I think it’s the original fan too also got a new fuse to 😅
the 328 should have the fan switch, but if you don't it most likely the fan, just read the forum, the few people was going over the similar problem, the fix was the fan replacement. good luck!
Hello, great video! I have problem with my e71 X6 5.0i 2008 it shows the engine overheating yellow light then turns into red and I changed the antifreeze hoses because it was leaking and now it’s good from that point but the cooling fan wasn’t working too so I ordered new fan and replaced it and again the engine is reaching about 100 degrees and increasing up to 120 and overheating but the fan isn’t starting or when it starts it’s not working on high speed it’s not working properly, what can cause this problem? Sometimes it just starts and stops and repeats this action, what should I look for?
I could think about a couple of things. The first one is the temperature sensor, which seats on the oil filter housing, Second, it's the same location, which is the oil temperature seems. they are directly related to the fan speed. as for the coolant temp. it's normal for BMW to run hoot, as 100-110C, but the fan should be on at this temp. Good luck, and let me know if you resolve the issue.
I have a Great tip for you!) The RealOEM.com diagrams part N. and more. It's a best friend for the BMW owners! www.realoem.com/bmw/enUS/showparts?id=3A93-USA-05-2012-F30-BMW-335i&diagId=61_3108 I chose the 2011 f30 n55. and it says it has a relay. But check it for yourself, type the VIN. Or get the right input on the web. In that case, you will know for sure!
What year, make, model is your car? I want to replace the relay on my 2008 X5 3.0si, which relay #7661503 apparently does not match. Thanks for any details!
Thanks for the pointing on my mistakes! the car is 2007 BMW X5 E70 N52 3.0si, Yes the Multi Purpose Relay (150 Amp) (Black) Mfg Part # 61367661503, that the same relay was installed on my car, check the link in description for the part i used! As far as the diagram on the top of the relay match with your that should work, also it's got to be 150Amp.
I have a 2009 E70 3.0. My fan runs on high when I start the car even when cold so I know it's not overheating. The fan runs for about 4 minutes while driving then shuts off. Then it comes on about 20 seconds later then runs for about 20 seconds and this cycle continues while I keep driving. Thoughts?
possible cause could be a failing water pump or thermostat, make sure to check the codes and see what you can find, the relay is just a pass trough, so it either work or not, temp. sensor could also be the case. good luck.
First is to make sure that you have this relay and if so, make sure it's working. www.realoem.com/bmw/enUS/showparts?id=UC72-EUR---E82-BMW-135i&diagId=61_3955 The problem also can be in the faulty switch. it's usually seats on the lower radiator housing, pass. side. but not sure if your car have it. make sure all related fuses is good. can you initiate fan from the computer"OBD II scanner"? you should be able to run it true computer.
Thank you so much for your help and yes my car has that relay it’s cracked on the top will that be the issue, I also tested the fan fuse and it has voltage but when I tested the connecter I connect to the fan and there is no voltage.
So I have a quick question I have a 2016 BMW X6 50i. Is the relay in the same place as your BMW because my fan isn’t working either and we tried changing the fan and everything else and none of that worked.
Yes, you should have one. and it's easy to check. Also if you gonna be ordering one, make sure you have the right Amp count, as far as I know, their variation of 150 & 130Amp. and make sure to disconnect the battery if you gonna be replacing one since it has a positive cable going directly in. www.realoem.com/bmw/enUS/showparts?id=KU63-USA-05-2016-F16-BMW-X6_50iX&diagId=61_3511
If I’m not mistaken, the e85 don’t have the fan relay, rather it had fan switch, it’s should be located on lower radiator hose, pass. Side. Check the realoem.com for the diagram. Also, you may have the fuse as well. Good luck man!
The simple answer is, you don't have one, the n54 have switch. you might have a relay in different location. you can check the "realoem . com", type your VIN and will give you all options and technicall spec of your car, then you can navigate to electronics and look for fan relay or cooling.
You can go on realoem.com If you type your vin there, it will show all the diagrams and parts specifically for your car. Also you be able to search for all the sensors and there location. Good luck!
The 3 Series usually don't have the Relay. If there one its gonna be behind the Battery, I wouldn't bother, the 3-series with n51 n52 n54 don't have one any way. You should have a switch on lower radiator housing, amzn.to/3M6XX8q. Make sure you have one first. www.realoem.com/bmw/enUS/showparts?id=PH73-USA-06-2008-E90N-BMW-328i&diagId=17_0350 - it's number 10 on the picture. passenger side.

Hi, Does the f02/2011 750li have a relay? If so, do you know the part # and location? I can’t seem to find the part on bmw dealers parts catalogue or any official documentation.

Is this only for x5? I've a 2007 x3 3.0 si and stuff says it's fuse 37. I've replaced the fan but I ran power to the old 1 and it was dead. Installed new fan and disconnected the coolant temp sensor and it's full blast..connect it back and the fan comes on and off but not at full speed. My obd2 bluetooth says it gets up to 222 at the most and it ll cool down to 210 max..it doesn't turn on when key on engine off..someone give me a clue..New to owning bmw myself. Family loved them over the years. All I remember was they all were worked on atleast on the cooling systems.

@@Makhnovets thanks so much, managed to get new Relay from BMW dealership, fitted it, but seems the fan still not coming on, confirmed again on ista, both Low and High speed work, also comes on with A/C on, should i perhaps try and change the coolant temperature switch?
@@Makhnovets Hi there, fit the new coolent temp switch, it sits in the block just above the egr, then checked all fuses behind the dash compartment , still have not had the fan come on, monitored temp to 104 degrees (C), should it have kicked in with this temp? or does it need to be higher?. thanks again for all the advice an assistance.
it could be the fan itself, the electric motor build from two stages, first for starting and second for running on speed, after starting the car try to spin the fan little bit, but be careful!!!! if it's still not starting it could be the relay, but most likely it's fan itself, any way it's cheaper to get a relay replaced first, then fan, like i said in previous comment, there nothing else in between the fan and DME except the relay. really small percentage can be the temperature sensor, but it's usually have problem with running on hi or low speed if it's sensor. good luck!
I have a 2009 328i x drive. My rad fan doesn't turn on when it needs to so I overheat. I'm getting power to the fan connector. I directly wired to 12v to see if it turns on and nothing. So I bought another rad fan from a wreckers and still won't turn on. I took 12v directly to the replacement fan and didn't turn on either. Could it be just another dead fan? Do you think it would be this relay? PS. I replaced the water pump and thermostat as well. Both rad hoses are hot.
Hi! First of all the only way to spin the fan without harming anything that true dealer obd tool, as inpa or any other that have ability to trigger the component. The second point is the relay, it's dirt cheap, 15x cheaper than fan, start from small and move toward big. Replace relay, than let me know what you got!
Cee Jay did you figure out how to get this rad fan to turn on? I am having the same problem, I checked the fuses, changed the rad fan, relay switch in the glove box. There is no fan switch on the rad hoses on this model 2009 bmw 328xi E90 like some others that do have a fan switch. The dealer showed me the schematics for my VIN and said there is no other related relay fan or switches. It is ECU controlled but I feel there is something I am missing. I am wondering if you can shed some light on this issue I have. Much appreciated if you have anything to suggest.
@@dili00007 I replaced the coolant temperature sensor on the engine block. It is located closer to your oil filter. Was a $30 part and worked right after I switched it! Hope this helps.
@@ceejay6628 Hey thanks for the reply. After looking at everything I figured out that there is 2 relay switches. 1 in the glove compartment and 2nd under the hood in the white fuse box. I bought a relay switch from the dealer and swapped them out. I started with the glove then the white fuse box. It ended up to be a bad relay switch in the white fuse box. Trying to diagnose this issue on your own is alot of trial and error. Standard OBDII readers cant read the codes. I also used a SNAP-ON reader and all it said was “cooling issue”. Only the dealer can tell you the real problem. The diagnosis from the dealer cost more than the actual part…
My fan comes off & on continuously and eventually will show overheat around 200F and becomes limp mode. The car only has 33k original miles. Any ideas?
@@Makhnovets This happened after cylinder #2 misfire due to a bad coil. Replaced all the coils + sparkplugs that's when I noticed the fan comes On & off while driving.
In theory, the relay has only one function, which is power passage. so if it's working-it's working. Make sure your AUC sensor has no messages, and also, the ambient temp sensor shows the right temperature. Do you have any messages on old? Just as context, my BMW X5 e70 was doing the same, because the AUC sensor was disconnected and wasn't working, try to clear the memory, make sure the AC is off when you start the car, and see if you have this problem, repeat with AC on. The fan speed is related to AC as well, that's why sometimes you got to make sure that you don't have a problem there. Good luck!
@@Makhnovets i have a code for the ambient air temp sensor but thats all. That shouldn't cause the fan to go full blast mode sometimes right. Mines a e90 2009 328i
If your fan is alway on, that means the coolant temperature sensor isn't working. The Relay is sort of switch, so if the fan is spinning that means relay working. ruclips.net/video/1ARsOcdPNGM/видео.html - for the sensor. ruclips.net/video/J2mUbrXZqFc/видео.html - overheating problems.
@@Makhnovets i actually replaced the sensor last night, but fan still wouldn't turn off. i tried bleeding the coolant system with heater and acceleration method, but tue water pump wouldn't activate, so im thinkin the water pump might be bad?
@@twistedcells you can see the electric coolant pump speed with obd tool, I think 500rpm/m it’s rated for, if the pump is on last breath, it will reduce the power in half, 250 or so. If pump working just as it’s should, the oil temp sensor also can be the problem, i had a case. The sensor seating on oil filter housing. Another question, is AC working fine? Have you hade any problems with it?
after ordering the obd, the pump data was unresponsive so i ordered the thermostat and water pump and popped them in tonight, problem solved! thankyou for the advice i really appreciate it🙌🙏
I think that you have radiator fan switch, which is seat on the passenger side radiator hose, at the top. I know that e60 have that type of setup! Good luck! Part number: 13 62 1 433 077 13627788077 1433077 13621433077

Bmw 335xi 08 Hey man Im getting the 2eff electric fan self diagnosis and 2f71 electronics box fan activation codes and my fan turns on full blast when its warming up and then sometimes its doesnt come and then csr starts overheating. Could the relay be the issue and if so im not seeing anything on location ?
First, the e90's don't have relay, in rare occasions they do but that will apply only to european cars. the 2eff is thermostate, or one of two element's that is made of, so I would assume you need replace thermostate and water pump while you there. the 2f71 on x5 for example is the fan that directly cool ECU box: www.realoem.com/bmw/enUS/showparts?id=FG41-EUR---E71-BMW-X6+35iX&diagId=12_1396
@@Makhnovets damnn man I just did my water pump and thermostat not too long ago , I cant imagine that it would go bad already. Maybe its a coolant temp sensor or fuse
That was a long way to fix it! With out my mess up, I wouldn't be able to make that vid for you!) Comment below if you have any Overheating related questions about N52/N54. See this video: What I did before replacing Relay - ruclips.net/video/J2mUbrXZqFc/видео.html
Got an o6 325i new radiator, fan , both temp sensors, reservoir tank and hoses and fuses seem to be fine, I just took it to bmw for three recalls which was the heater core, airbag, and wire harness to it, first the fan wouldn’t turn on but the next day it was working fine then again no cold ac so ichecked the fan and it wasn’t turning, would this be my best bet ? Thank you!
@@abrahamvera6366 like in the video there are loose connection somewhere so just follow the ground cable and a positive cable and make sure the intact, because I had exact same issue and as you seen it in the video I had loose connection to the relay.
Going to try this fan relay just bought it for 35$ at bmw but if not it might be wiring because my expansion tank did blow up and got all over the connector and wire hoepfully it’s just the relay tho great video!
I have Bmw 320d 2005 e90 2l diesel and my radiator fan doesnt stop spinning until i switch the engine off. What could this be ive replaced thermostat and sensor but radiator fan starts everytime i start the car it very loud and annoying sounds like a jet. Ive also replaced the radiator fan
Test it with A/C off. Another point if the thermostat stuck open or water pump reduced the speed the fan will work in full. Make sure you check if temperature stay at 95c’. Check the obd for water pump speed, or make sure you don’t have the messages that water pump is missing or reduce power.
test it true the INPA or ISTA... did you check the fuses and relay? that's two cheapest steps, the last one gonna be replacing the fan itself, like i post in the previous comment, in between the fan and computer only relay, so if the relay and the fan are new, and the fuses are good, check the wiring, there theory about the thermostat, which is showing the wrong data or so it's not gonna heart to replace it too., but i definitely would connect the computer and check if there any messages... Good luck, hope to here from you soon!
O yeah my ac doesn't blow cold also..I tried recharge and nope..I read somewhere my coolant fan relies on a couple sensors..I read maybe the ac pressure is related to my new fan slow off and on speed?? Any definitive suggestions would be appreciated
so i need some help on my f30 im getting this error “1A2004 electric fan control cable disruption” and or electric fan self-diagnosis stage 4: severe fan error can some one tell me if they had that problem before what would it be

Coolant or Oil temperature sensor could show faulty data, and they pretty cheap, and easy to replace, I would start with them if I didn’t do it by now. Dos it do it all the time? Do you have any codes?
My dad 2008 BMW x3 3.0 just had a new thermostat put in and it didn’t help and it overheated the second time after my dad got it back what do you guys think it would be?
I have code p0480 on my 2009 bmw 335i pop up on my scanner its causing my car to overheat like 3-4 times but i know its not a blown head gasket even tho i had 2 shops tell me it was so im trying to hunt down the issue on my own is it in the same place and is mine a switch or module?
You have a switch. There tester for head gasket like this one, amzn.to/3Ee0J9y Get one it’s 99% accurate, in that case, you will know for sure. Before getting into any repair or replacement. N54 very rarely has head gasket problems. But the code is for a cooling fan, make sure the water pump and thermostat working correctly, the main symptom is the fan kicking on full speed, or it might was doing it before, in that case, you toast the fan. check the water pump speed, also try to actuate the cooling fan, there 4speeds for the fan, you can trigger it true INPA or OBD that supports the components trigger. See the readings off the temperature sensor and the consistency of the temperature rising. There are 3 things you need to check, cooling fan waterpump&thermostat and temperature sensor or switch. Good luck!

That could be long conversation, I’ll try to keep my thoughts short, what i want to say that the car is not overrated whatsoever, from my perspective it’s underrated, for the reason of maintaining, if you check the BMW maintenance shit, it’s say when and what you will need to replace at curtain mileage, and if you not ready to do that don’t buy the car on the first place, buy toyota which is cheap inside and outside, and doesn’t have advanced technologies inside, same as riding experience, quality of ride, and more, I know it’s not perfect, rither tessla or Ferrari, there also have they good and bad aspects. Non of the toyota will cach the eye same as BMW or Mercedese! The N52 and N54 engine’s are very reliable, in terms if you do proper maintenance!
Bro I fucking took my wheel off and the wheel liner and my shit was not there. This is not true for e60 I'm pissed I wasted my time and still can't find the damn location
Why would you just assume that an E60 would be the same as an X5? They're completely different models so the locations of things like relays could also be completely different.
The “realoem” have diagrams, in Electronics section you should be able to find what you need. E70 and E60 has completely different components structure plus the year is a big factor.
@jessepullen6109 I’ll double check with that, the chassis in X5 is very similar-same as 5series, but electrically would be different. My apologies if that was my mistake. Will make sure to update the information on that if so!
I don’t have any codes but the fan is stuck on high and overheating, do you think this part would do the trick? It used to get stuck on high for a few min then disappeared but this week it hasn’t gone away ever since.
The Temperature sensor and Relay, Replace both of them. I would say the temp sensor multi-functioning, the one that seats on the oil Filter housing, it's cheap and easy to replace, you only need a 22-mm or 24-mm socket(ruclips.net/video/1ARsOcdPNGM/видео.html). The relay is cheap, so I would replace it as well.
you don't have the same location or the same relay, the one you looking for is in the passenger compartment fuse box, Number:45, 60A relay. Also check the luggage compartment Number: 127, 5A
Question: 2015 X1 xdrive28i has the same issue, no fan is working. The relay should be at same location? Do I need OBD memory save plug BEFORE I disconnect the battery? Any suggestion? Thank you!
The relay gonna be a little different, and it's in the DME box. see the pic. here www.realoem.com/bmw/enUS/showparts?id=VL13-USA-02-2015-E84-BMW-X1_28iX&diagId=61_3822 It does not necessarily need to disconnect the battery to replace the Relay, but it's up to you. I never had an issue with replacing the fuse or relay on hot. just make sure the car is asleep (you basically have the key off the ignition and the car door is closed for at least 30sec).(or when the welcome light or any LED in the car is not lightning.)

I chose the 2011 f30 n55. and it says it has a relay. But check it for yourself, type the VIN. Or get the right input on the web. In that case, you will know for sure!
What year, make, model is your car? I want to replace the relay on my 2008 X5 3.0si, which relay #7661503 apparently does not match. Thanks for any details!
Thanks for the pointing on my mistakes! the car is 2007 BMW X5 E70 N52 3.0si, Yes the Multi Purpose Relay (150 Amp) (Black) Mfg Part # 61367661503, that the same relay was installed on my car, check the link in description for the part i used! As far as the diagram on the top of the relay match with your that should work, also it's got to be 150Amp.
I have a 2009 E70 3.0. My fan runs on high when I start the car even when cold so I know it's not overheating. The fan runs for about 4 minutes while driving then shuts off. Then it comes on about 20 seconds later then runs for about 20 seconds and this cycle continues while I keep driving. Thoughts?
possible cause could be a failing water pump or thermostat, make sure to check the codes and see what you can find, the relay is just a pass trough, so it either work or not, temp. sensor could also be the case. good luck.
Hello great video I have a 08 bmw 135i and I have the 2efe code I got a new fan from wrecker and still not turning on and I still have the 2efe code?
First is to make sure that you have this relay and if so, make sure it's working. www.realoem.com/bmw/enUS/showparts?id=UC72-EUR---E82-BMW-135i&diagId=61_3955
The problem also can be in the faulty switch. it's usually seats on the lower radiator housing, pass. side. but not sure if your car have it. make sure all related fuses is good. can you initiate fan from the computer"OBD II scanner"? you should be able to run it true computer.
Thank you so much for your help and yes my car has that relay it’s cracked on the top will that be the issue, I also tested the fan fuse and it has voltage but when I tested the connecter I connect to the fan and there is no voltage.
Can you activate the fan from the software? Like obd scanner?
Unfortunately I do not have one
@@guerrerola1237 try to replace the relay and a switch, two main components that will trigger the fan. Good luck!
*my E46 coolant fan stays on doesn't turn off is this probably the solution?*
Have you found problem? Have you replaced pump/thermostat already? Are all your belts working?
Does this go for the x3 as well?
Not sure, newer owned a x3 you can check the realoem.com for the diagram.
So I have a quick question I have a 2016 BMW X6 50i. Is the relay in the same place as your BMW because my fan isn’t working either and we tried changing the fan and everything else and none of that worked.
Yes, you should have one. and it's easy to check. Also if you gonna be ordering one, make sure you have the right Amp count, as far as I know, their variation of 150 & 130Amp. and make sure to disconnect the battery if you gonna be replacing one since it has a positive cable going directly in.
www.realoem.com/bmw/enUS/showparts?id=KU63-USA-05-2016-F16-BMW-X6_50iX&diagId=61_3511
Do you know where the relay is on a e85 z4
If I’m not mistaken, the e85 don’t have the fan relay, rather it had fan switch, it’s should be located on lower radiator hose, pass. Side. Check the realoem.com for the diagram. Also, you may have the fuse as well.
Good luck man!
I cant find on my 2007 bmw 335i n54 e93. Is it in the same spot?
The simple answer is, you don't have one, the n54 have switch. you might have a relay in different location. you can check the "realoem . com", type your VIN and will give you all options and technicall spec of your car, then you can navigate to electronics and look for fan relay or cooling.
I have bmw x1 2012 model N20 engine. Can you help me to allocate coolant fun relay. Where is it?
You can go on realoem.com
If you type your vin there, it will show all the diagrams and parts specifically for your car. Also you be able to search for all the sensors and there location. Good luck!
Plz can u tell me where the relay for the 3 series N52 is located?
The 3 Series usually don't have the Relay. If there one its gonna be behind the Battery, I wouldn't bother, the 3-series with n51 n52 n54 don't have one any way.
You should have a switch on lower radiator housing, amzn.to/3M6XX8q. Make sure you have one first. www.realoem.com/bmw/enUS/showparts?id=PH73-USA-06-2008-E90N-BMW-328i&diagId=17_0350 - it's number 10 on the picture. passenger side.
Is it the same on a 04 X5 3.0i
Not sure, there might be switch, or just check the realoem.com you will find diagram there.
Does it work on a 2007 x3
Not sure, but you can check realoem for diagram, it should be under electronic/Relay.
Does a 2011 528i hav the same fan relay/control module. Fan on my car doesn’t run at high speed. It constantly runs at low speed and just been having this issue for a few week. No codes or anything like that.
Check the recent comments, otherwise i will update in a day...
Qual era o problema?
Hi,
Does the f02/2011 750li have a relay? If so, do you know the part # and location? I can’t seem to find the part on bmw dealers parts catalogue or any official documentation.
Hey. The realoem,com is the best place for diagrams and part number research.
If you use your vin on the main page, it will show your build.
But that’s what I found:

@@Makhnovetsthanks. I did find it in the trunk. Can these be tested with a multimeter?
Do you know if the bmw 335d has the same relay?
Yes, there same principle, but could be different location for it!
Is this only for x5? I've a 2007 x3 3.0 si and stuff says it's fuse 37. I've replaced the fan but I ran power to the old 1 and it was dead. Installed new fan and disconnected the coolant temp sensor and it's full blast..connect it back and the fan comes on and off but not at full speed. My obd2 bluetooth says it gets up to 222 at the most and it ll cool down to 210 max..it doesn't turn on when key on engine off..someone give me a clue..New to owning bmw myself. Family loved them over the years. All I remember was they all were worked on atleast on the cooling systems.

What y of manufacture is your car?
Also, you can check realoem.com
There you can find the parts by typing your VIN, and see diagram! Start from there. From now on That site will be your BMW Bible.
Do you know the location of that on a 2009 bmw 128i?
Upper radiator housing at the passenger side that's for 5series radiator switch, but it's more for 3.0 with no turbo, the 335 location might change. also you can search for radiator fan switch or so.
HiThere, i have an X1 N47/2,0 D, have the same problem, fan does not come on, it works when i put aircon on, and also comes on with Ista connected on both low and high speed, any idea where the relay might be? perhaps will try and replace and hope for the best.

@@Makhnovets thanks so much, managed to get new Relay from BMW dealership, fitted it, but seems the fan still not coming on, confirmed again on ista, both Low and High speed work, also comes on with A/C on, should i perhaps try and change the coolant temperature switch?
Yeah, the switch will be my guess, also make sure you do the have any codes for ac, for example AUC Sensor or so.
@@Makhnovets Hi there, fit the new coolent temp switch, it sits in the block just above the egr, then checked all fuses behind the dash compartment , still have not had the fan come on, monitored temp to 104 degrees (C), should it have kicked in with this temp? or does it need to be higher?. thanks again for all the advice an assistance.
So my fan twitches but doesn’t fully turn on, Would this be my best bet if my fan wants to turn on but doesn’t fully turn on ?
it could be the fan itself, the electric motor build from two stages, first for starting and second for running on speed, after starting the car try to spin the fan little bit, but be careful!!!! if it's still not starting it could be the relay, but most likely it's fan itself, any way it's cheaper to get a relay replaced first, then fan, like i said in previous comment, there nothing else in between the fan and DME except the relay. really small percentage can be the temperature sensor, but it's usually have problem with running on hi or low speed if it's sensor. good luck!
OP, did you ever fix the twitching fan issue? Was it the fan or the relay?
I’m having the same issue is fan or relay bcz my fan works on a/c and twitches when idling also just changed thermostat
I have a 2009 328i x drive. My rad fan doesn't turn on when it needs to so I overheat. I'm getting power to the fan connector. I directly wired to 12v to see if it turns on and nothing. So I bought another rad fan from a wreckers and still won't turn on. I took 12v directly to the replacement fan and didn't turn on either.
Could it be just another dead fan? Do you think it would be this relay?
PS. I replaced the water pump and thermostat as well. Both rad hoses are hot.
Hi! First of all the only way to spin the fan without harming anything that true dealer obd tool, as inpa or any other that have ability to trigger the component. The second point is the relay, it's dirt cheap, 15x cheaper than fan, start from small and move toward big. Replace relay, than let me know what you got!
Cee Jay did you figure out how to get this rad fan to turn on? I am having the same problem, I checked the fuses, changed the rad fan, relay switch in the glove box. There is no fan switch on the rad hoses on this model 2009 bmw 328xi E90 like some others that do have a fan switch. The dealer showed me the schematics for my VIN and said there is no other related relay fan or switches. It is ECU controlled but I feel there is something I am missing. I am wondering if you can shed some light on this issue I have. Much appreciated if you have anything to suggest.
@@dili00007 I replaced the coolant temperature sensor on the engine block. It is located closer to your oil filter. Was a $30 part and worked right after I switched it! Hope this helps.
@@ceejay6628 Hey thanks for the reply. After looking at everything I figured out that there is 2 relay switches. 1 in the glove compartment and 2nd under the hood in the white fuse box. I bought a relay switch from the dealer and swapped them out. I started with the glove then the white fuse box. It ended up to be a bad relay switch in the white fuse box. Trying to diagnose this issue on your own is alot of trial and error. Standard OBDII readers cant read the codes. I also used a SNAP-ON reader and all it said was “cooling issue”. Only the dealer can tell you the real problem. The diagnosis from the dealer cost more than the actual part…
My fan comes off & on continuously and eventually will show overheat around 200F and becomes limp mode. The car only has 33k original miles. Any ideas?
I would blame the temperature sensor, although you should have some codes?
@@Makhnovets This happened after cylinder #2 misfire due to a bad coil. Replaced all the coils + sparkplugs that's when I noticed the fan comes On & off while driving.
So I changed my cars coolant temp sensor but sometimes when I start the car the radiator fan goes full blast sometimes. Do you believe is the relay
In theory, the relay has only one function, which is power passage. so if it's working-it's working. Make sure your AUC sensor has no messages, and also, the ambient temp sensor shows the right temperature. Do you have any messages on old?
Just as context, my BMW X5 e70 was doing the same, because the AUC sensor was disconnected and wasn't working, try to clear the memory, make sure the AC is off when you start the car, and see if you have this problem, repeat with AC on. The fan speed is related to AC as well, that's why sometimes you got to make sure that you don't have a problem there. Good luck!
@@Makhnovets i have a code for the ambient air temp sensor but thats all. That shouldn't cause the fan to go full blast mode sometimes right. Mines a e90 2009 328i
can that be my problem? only thing is my fan is always on and reads my engine compartment is too hot, but the actual temp is good.
If your fan is alway on, that means the coolant temperature sensor isn't working. The Relay is sort of switch, so if the fan is spinning that means relay working.

@@Makhnovets i actually replaced the sensor last night, but fan still wouldn't turn off. i tried bleeding the coolant system with heater and acceleration method, but tue water pump wouldn't activate, so im thinkin the water pump might be bad?
@@twistedcells you can see the electric coolant pump speed with obd tool, I think 500rpm/m it’s rated for, if the pump is on last breath, it will reduce the power in half, 250 or so.
If pump working just as it’s should, the oil temp sensor also can be the problem, i had a case. The sensor seating on oil filter housing.
Another question, is AC working fine? Have you hade any problems with it?
after ordering the obd, the pump data was unresponsive so i ordered the thermostat and water pump and popped them in tonight, problem solved! thankyou for the advice i really appreciate it🙌🙏
08 528i can’t find the relay anywhere. Anyone know where? Much appreciated
I think that you have radiator fan switch, which is seat on the passenger side radiator hose, at the top. I know that e60 have that type of setup! Good luck!

Hey man Im getting the 2eff electric fan self diagnosis and 2f71 electronics box fan activation codes and my fan turns on full blast when its warming up and then sometimes its doesnt come and then csr starts overheating. Could the relay be the issue and if so im not seeing anything on location ?
First, the e90's don't have relay, in rare occasions they do but that will apply only to european cars. the 2eff is thermostate, or one of two element's that is made of, so I would assume you need replace thermostate and water pump while you there. the 2f71 on x5 for example is the fan that directly cool ECU box: www.realoem.com/bmw/enUS/showparts?id=FG41-EUR---E71-BMW-X6+35iX&diagId=12_1396
@@Makhnovets damnn man I just did my water pump and thermostat not too long ago , I cant imagine that it would go bad already. Maybe its a coolant temp sensor or fuse

Go on “realoem com” and check the diagram. Since I’m not sure if it has the same relay. As far as I know it doesn’t.
Thank you

Got an o6 325i new radiator, fan , both temp sensors, reservoir tank and hoses and fuses seem to be fine, I just took it to bmw for three recalls which was the heater core, airbag, and wire harness to it, first the fan wouldn’t turn on but the next day it was working fine then again no cold ac so ichecked the fan and it wasn’t turning, would this be my best bet ? Thank you!
@@abrahamvera6366 like in the video there are loose connection somewhere so just follow the ground cable and a positive cable and make sure the intact, because I had exact same issue and as you seen it in the video I had loose connection to the relay.
Going to try this fan relay just bought it for 35$ at bmw but if not it might be wiring because my expansion tank did blow up and got all over the connector and wire hoepfully it’s just the relay tho great video!

Hey did you find the a solution to your fan ??
Test it with A/C off. Another point if the thermostat stuck open or water pump reduced the speed the fan will work in full. Make sure you check if temperature stay at 95c’. Check the obd for water pump speed, or make sure you don’t have the messages that water pump is missing or reduce power.
2005 Bmw x5 v6 ac fan has no power going to it any suggestions?
test it true the INPA or ISTA... did you check the fuses and relay? that's two cheapest steps, the last one gonna be replacing the fan itself, like i post in the previous comment, in between the fan and computer only relay, so if the relay and the fan are new, and the fuses are good, check the wiring, there theory about the thermostat, which is showing the wrong data or so it's not gonna heart to replace it too., but i definitely would connect the computer and check if there any messages... Good luck, hope to here from you soon!
O yeah my ac doesn't blow cold also..I tried recharge and nope..I read somewhere my coolant fan relies on a couple sensors..I read maybe the ac pressure is related to my new fan slow off and on speed?? Any definitive suggestions would be appreciated
so i need some help on my f30 im getting this error “1A2004 electric fan control cable disruption” and or electric fan self-diagnosis stage 4: severe fan error can some one tell me if they had that problem before what would it be

What exactly was your code? Auxiliary fan activation: line disconnected?
The code is "2efe electric fan, activation"
That's mean either far or relay not working.
my car is 2011 x5 e70 fan is working but its come high speed...anybody know about that ???.. thanks..
Coolant or Oil temperature sensor could show faulty data, and they pretty cheap, and easy to replace, I would start with them if I didn’t do it by now.
Dos it do it all the time? Do you have any codes?
My dad 2008 BMW x3 3.0 just had a new thermostat put in and it didn’t help and it overheated the second time after my dad got it back what do you guys think it would be?
What code you get? also, do the front fan spin when the car is staring or running?
No the radiator fan does not spin when we start it up and let it run
I have code p0480 on my 2009 bmw 335i pop up on my scanner its causing my car to overheat like 3-4 times but i know its not a blown head gasket even tho i had 2 shops tell me it was so im trying to hunt down the issue on my own is it in the same place and is mine a switch or module?
You have a switch. There tester for head gasket like this one, amzn.to/3Ee0J9y
Get one it’s 99% accurate, in that case, you will know for sure. Before getting into any repair or replacement. N54 very rarely has head gasket problems.
But the code is for a cooling fan, make sure the water pump and thermostat working correctly, the main symptom is the fan kicking on full speed, or it might was doing it before, in that case, you toast the fan. check the water pump speed, also try to actuate the cooling fan, there 4speeds for the fan, you can trigger it true INPA or OBD that supports the components trigger. See the readings off the temperature sensor and the consistency of the temperature rising. There are 3 things you need to check, cooling fan waterpump&thermostat and temperature sensor or switch. Good luck!

It’s not the worst engineering decision, but it’s not the best either 🤣
German engineering lol😂
Expensive car but parts break premature. Over rated car.
That could be long conversation, I’ll try to keep my thoughts short, what i want to say that the car is not overrated whatsoever, from my perspective it’s underrated, for the reason of maintaining, if you check the BMW maintenance shit, it’s say when and what you will need to replace at curtain mileage, and if you not ready to do that don’t buy the car on the first place, buy toyota which is cheap inside and outside, and doesn’t have advanced technologies inside, same as riding experience, quality of ride, and more, I know it’s not perfect, rither tessla or Ferrari, there also have they good and bad aspects. Non of the toyota will cach the eye same as BMW or Mercedese!
The N52 and N54 engine’s are very reliable, in terms if you do proper maintenance!
I own bmw, Mercedes, Toyota and Tesla. Bmw break down prematurely. That’s all I’m saying, breaking down before recommending to change parts.
Bro I fucking took my wheel off and the wheel liner and my shit was not there. This is not true for e60 I'm pissed I wasted my time and still can't find the damn location
Why would you just assume that an E60 would be the same as an X5? They're completely different models so the locations of things like relays could also be completely different.
The “realoem” have diagrams, in Electronics section you should be able to find what you need.
E70 and E60 has completely different components structure plus the year is a big factor.
@@Makhnovets no doubt they are different. But in the video he says e60 is in the same spot ...
@jessepullen6109 I’ll double check with that, the chassis in X5 is very similar-same as 5series, but electrically would be different.
My apologies if that was my mistake.
Will make sure to update the information on that if so!
I don’t have any codes but the fan is stuck on high and overheating, do you think this part would do the trick? It used to get stuck on high for a few min then disappeared but this week it hasn’t gone away ever since.
The Temperature sensor and Relay, Replace both of them. I would say the temp sensor multi-functioning, the one that seats on the oil Filter housing, it's cheap and easy to replace, you only need a 22-mm or 24-mm socket(ruclips.net/video/1ARsOcdPNGM/видео.html). The relay is cheap, so I would replace it as well.
So I have a quick question I have a 2010/05 BMW X5 30DX. Is the relay in the same place as your BMW because my fan isn’t working
Send me last 7 of the vin.

It does not necessarily need to disconnect the battery to replace the Relay, but it's up to you. I never had an issue with replacing the fuse or relay on hot. just make sure the car is asleep (you basically have the key off the ignition and the car door is closed for at least 30sec).(or when the welcome light or any LED in the car is not lightning.)
