Absolutely the best vids I have found. e70 n55 with valve cover knock, trying all your suggestions, in order. Thank goodness I found you, you just saved my car. Thank you sir
Hello, Sorry to hear your N55 has a knock. Often this can be a bottom end noise due to worn out rod bearings. In some cases the rod bearings can be replaced and the engine is still ok in some cases if there is damage to the crank the engine may need replacement.
Good to see you're still putting out new videos. You're a great mechanic, informative and very clear and easy to understand. I appreciate your time and help you've given me on my E46.
Thanks bud!
@@AskTheCarExperts You're welcome. I have a question: I'm using a Foxwell NT510 Elite. One of the codes it reads as an error is: IHKA: AUC sensor. What is that and WHERE is it? I have other codes but, I'll not bombard you. Thank you.
@@standtall7646 The AUC sensor is the "smell" sensor to close the fresh air flaps when it detects excess fumes from other vehicles. It is located in the engine compartment bulk head near the fresh air inlet area. Usually on the passenger side.
@@AskTheCarExperts Thank you. I'll look at that today. The other "error" code is of big concern: I have an airbag light on instrument cluster. That code is: Airbag ZAE. My connections under seat look connected and tight and my car is very clean. No rust or corrosion under my seat or on my car anywhere. Another error is: MRS: Seat occupancy recognition (SBE1). I don't know if they are the same issue, combined or not. A little puzzled.There was a recall several years back on steering wheel airbag but, dealer said it had the correct airbag installed and required no Recall Upgrade. Thank you, for your time and help, again.
@@standtall7646 No problem. Did the airbag light come on before the airbag was checked? If you clear the code does the warning come right back?
Thank you very much for this brilliant information！My N55 has been showing this code for almost a year, and I have been experiencing rough idles from cold starts, but everything goes to normal once the engine warms up. I have to clear adaptations and let the car idle for more than 20 minutes for multiple times before actually driving it, then I can somehow work around with any rough idles issues. I never figured out why the procedure I tried somehow works, but your video provides a more reasonable explanation. I will definitely give it a try to unplug the purge valve, and hope it can solve this issue much faster. Thanks again!
Glad to hear the info is helpful!
Did your problem fixed?
I see visible oil leak at rear mail seal :( , Also at idle I can hear alot of noise coming from the rear main area
@@tronix19 My car has been stable for the past year or 20k miles and I did not have to clear code or reset adaptation, so I have been driving without any rough idle issue. But I know the problem will return as soon as I clear code or reset adaptation....
@@DoradoDevOps You might want to try change your valve cover first? I have seen many N55 users report the crankcase ventilation system is leaking and changing valve cover can address it
Brilliant info, Roger, thanks for sharing your skill and experience.
Ice balls?!? Amazing. Never heard of that.
It was super cool to see! And feel! But not cool for the owner 😕
Very useful info, thanks.. Having a challenge identifying the exact location of the tank vent value on a x5 2013.
It should be right on the driver side toward the from under the intake. I also show it on my video for the launch because I activate it as a test. Hope this helps.
Hey, I have a 2013 BMW 335i and have the issue - 101F01 - Air Mass System, Plausibility: Calculated Air Masses In The Air Intake System Not Plausible.
Do you have any recommendations on what to try for this? The idle is extremely rough and most of the time cuts out. Did a smoke test and since upgraded the turbo inlet and charge pipes, no more leaks but the car is still having the rough idle
Any suggestions is much appreciated

Dude, you saved the day! Unplugged my gas tank vent hose and let my N55 idle for 15 minutes, cleared codes, plugged hose back in and it fixed the check engine light and idle stumble. My battery also needs replaced, wondering if this triggered this?
Awesome bud! Battery voltage issues can do some odd things.
Found my leak around the seam of the map sensor next to the throttle and second leak at the crank case vent hose on
the valve cover. 2012 bmw x3 35i n55.
@@yoube449 Sweet! Those small leaks can cause big issues.
@@AskTheCarExperts yes I got dtc 101f01 now I'm waiting on parts after finding where the leak were.
I will give you an update after the repairs.
@@yoube449 Sounds good!
Update on the 101F01 code .Amazon delivered my parts on time Crankcase vent hose and Pvc valve was replaced i didn't replace the intercooler hose cause i was able to seal the base of the intercooler hose that mounts the map sensor. Cleared the code and took it on a test drive. The check engine light would normally come back right away but it never came back on.The on board computer still reads it as a permanent code but that should clear after driving for a bit. NO MORE CHECK ENGINE LIGHT 🤣🤣. Thank for sharing your knowledge with me.👍
@@yoube449 That is great news! Great job doing your diagnosis and finding those leaks!
Your videos have been the most helpful. I just subscribed. I got this fault code 28A0 after I placed the cap on the A/C line (small). Any suggestions?

Great video @askthecarexperts ! Liked and subscribed!
Code 28A0 appeared after replacing the rear duct (aka Intercooler Pipe). Could the rear duct replacement have triggered that code?
Thanks!
Thanks!
It could be an air leak. Do you have a smoke tester?
@@AskTheCarExperts don’t have one, but did the trick you showed in the video and so far the code hasn’t showed up again.
PS: I lost the cable clip while removing it 😵💫… it was swollen by the engine bay… another one is on its way.
Thanks!
Great video. I developed this code after my belt came off last night. So I’m guessing the front main seal most likely is damaged.
Hello, Sorry to hear you had this issue. Most likely it is damaged from the belt. Happens quite often.
Dealing with p122f now after changing bank 1 02 spark plugs not sure what vacuum leak to check
Smoke test the engine just past the filter housing. Even a small leak cam cause this. Often the charge air tube leaks.
Did you figure out what it was? Having this code on a n55 i just bought
this can also be caused by a slow to reveal itself intake camshaft wearing out the bearing ledges.
You are absolutely right Joe
I had the same issue. My valve cover had a micro-crack, and since i replaced it, the code newer came back!!!!
Glad you found it! That can be a tough thing to trace. Thanks for posting!
@@AskTheCarExperts
One thing though were I almost gave up was fixing a P0172 rich mixture problem.
I ended up replacing all injectors, spark plugs, vanos positioning sensors, crankcase positioning sensor, mass airflow sensor, manifold pressure sensors, charge pipe, throttle body, ignition coils, etc. and none of it did anything….. i lived with this issue for almost 3 years and nobody could really help me.
Just last month I notices that the boost pipe (which goes out from the intercooler to the charge pipe, and then to the throttle body)
Wasn’t attached properly to the IC. Also the inner seal was so loose inside that air escaped out of the pipe: hence rich condition, since measured air escaped out of the pipe and thus less air entered in the intake manifold.
Changing the inner rubber seal and attaching the pipe properly solved that issue. It felt like winning an argument agains my girlfriend.
It was amazing 🤩

Hi Roger, GREAT INFO!! great video!! i HAVE A 2013 N55 well maintained and oil changes/ new top pan(with new oil cap)/ new oem spark plugs/ new OFHG/ and as to be sure, preventative maintenance new belt and pulleys/tensioner, this engine is dry and no leaks for about 30 thousand miles ago.But i have this same code 28AO, that will pop up and go away occasionally... Otherwise the vehicle is fine and this code has be on/off for 10 months and i feel and notice that, if i always warm up the cold engine for 15 minutes before i drive, the code wont appear, it is a nuisance and annoying I use a ANCEL BM700 obd code reader. the vehicle it has 177 kilometres on it now. ty for your Thoughts, comments and response
Hello :) Such a crazy fault code. If there are no unmetered air leaks I would suspect the high pressure fuel pump.
@@AskTheCarExperts ,ty Sir, i appreciate you input. i well get a check a the fuel pump pressure and see how it goes, ty keep posting Great Videos!! ty
@@battlehrfred same boat here. I am wondering if there is any update on your side? really appreciate it!
@@yizhonghu1522 ,Hi, my vehicle has now 200 thousand on it since last year.. so this means,at least my opinion,says, its not the fuel pump that is giving me a issue, if it was my fuel pump it would have been shut down since last year, but nope, runs fine, but again 28A0 CODE is still showing up. i am going to do a "smoke" test on the Engine itself and also im going to do the intake duct system upcoming soon.but again, i do delete the 28A0 code and it comes return immediately after i start it up . otherwise the vehicles engine is just fine ty
@@battlehrfred My 2013 N55 e70 is also well-maintained and I have had it for the past 7 years. Started to leak though and I dealt with most of the leaks. The 28A0 comes and goes occasionally. My shop said it was due to a leak on the valve cover so I got a new OEM valve cover. The code was clear for 1.5 months after the new valve cover but it comes back again now. The vehicle runs fine, no noticeable issue.
Is the tank vent valve electrical connector the one with the sliding metal clip? O have a 2013 N55 F10. It is not clear in the cutout picture in the video. Of course my old eyes don't work as well as they used to.
Hi Ron, Glad to help. Yes that push sliding clip is the task vent valve. You can send me a picture of it if you want me to verify for you. Askthecarexperts@gmail.com
Great video, thank you.
I have a 2011 BMW X25 N55 ... and this damned fault code is a real pain in the a...ss.
Have been chasing it since 6 months. I have replaced so many parts and I am very frustrated.
When I start the car, cold or hot, it will rev up itself to 1500 rpm, then go back to 1000 rpm and then gradually down to 650.
The idle needle is stable but I feel rough idle on my seat, intermittent vibration. When chcking N55 start up on youtube, it seems that mine is not so normal (rev to 1500 and go down)
CEL is ON. Fault code is 101F01. I have done the idle procedure countless times, but the fault code will come back everytime.
I have replaced so many parts...Spark plugs, ignition coils, turbo inlet pipe, turbo outler pipe, intercooler, charge pipe, TMAP sensor, Hotfilm MAF sensor, intake manifold gasket, throttle body, puge valve)...
The only light in the dark tunnel I have seen is that one day, after disconnecting purge valve, I cleared the code and I did not reconnect the purge valve electrical connector, I drove the car like that for 3 days.
I put my ISTA-D the 3rd day and checked but the 101F01 code did not show up for those 3 days.
I had CEL ON but it was because the purge valve was disconnected (tank vent disconnected).
So I think my problem may be on the Evap side, because when I isolate it, the code wanish.
When I check on ISTA, with tank vent connected, I can see several occurences at different speed, rpm and times of this 101F01 code. I believe it follows normal purge valve operation openings and closing during driving;
I don't have smoke machine unfortunately to check tank vent system for leaks. But I suspect that my problem maybe on the tank side. There is no fuel smell in vehicle, I can fill my tank full with problem.
Any suggestion welcomed
That would be an interesting failure for this code. You can remove the TVV and see if it is closed correctly by blowing through it. At this point I would replace it and recheck since that seemed to make a difference.
@@AskTheCarExperts Hi AskTheCarExperts! I think I have a very similar issue as Smile Iso9001 here and have been working on for more than 1 year. Can you help explain why these N55 with 101F01 code tends to have very rough idle at cold but gradually smooth out when it warms up? Is it because those hydrocarbons are being burnt during the warm up process? Thank you so much!
Smile Iso 9001 I have the same issue as you are experiencing and also do not have the p112f code reappear if I leave the purge valve disconnected. Did you have any luck tracing your Evap side ? Did you replace the purge valve with success?
@@markzuege8641 Hi, purge valve was replaced but no luck.
I have ordered new valve cover from FCP. I am waiting for other parts like coils and spark plugs, then I will replace valve cover and spark and coils.
Wish me luck.
I intend to do the job in 2 weeks (waiting for the parts ordered). I have already the new valve cover available but I don't want to do double work so better for me to wait for plugs and coils and replace all at the same time I do the valve cover.
@@SmileIso Ok, interesting I ended up doing the valve cover, I also changed out my intake cam and bearing caps for new. I had the p112f reappear but after leaving purge valve unplugged no error.. ended up driving around with it unplugged, blowing out evap lines and checking for leaks. 3 days later I reconnected the evap system now light is out, seem it has resolved my issues finally. Goodluck with yours!. Mark
Just had the 28A0 after I deleted adaptations when replacing the tank purge valve. Im going to try and do the adaptations with the valve unplugged
I have fixed a lot of cars with that trick. I hope that works for you as well!
Make sure to subscribe as I will be giving away a smoke machine in the near future.
@@AskTheCarExperts sure will, one thing to add is that now I get pops and bangs because of the unmetered fuel fumes 🤣 im sure going to miss that but prefer a CEL free X5.
Did that work for you? I’ve been trying to solve 28A0 for 2 months my car has been sitting! pls help
@@HamptonEdwards I had to put my old tank recirculating valve back, the new one was either defective or was the incorrect for the fabrication year.

Hi Sir, I have been having this 28A0 CODE for 2 years now,(2013 bmw x5 35i x 3.0 litre gas engine 193,000 now )which sets off these codes,2EFE 2EFF,2F00,2EE2,2EE6,2EE9. which is caused to appear because of the 28A0 CODE... i have had this code, 3164 (fuel tank system ,2nd inlet port malfunction.)So I purchased a new valve from Rock auto, and the part numbers was for my x5 as i checked cross reference with oem bmw part number to reassure it was the right one for my x5. that is fixed fine now, but the 28A0 is still givin me issues and continually appear and continues to give my vehicle surging and surging for a about 3 times in the COLD temperature only, before it sputters and finally levels off ok after 10 seconds or so , if its really cold (1 degree) it can and do chug chug and has shut off on some occasions and had to restart it. i live on the East Coast of Canada and the weather is getting colder here now and thats when this ongoing ordeal,Chug,chug continues to be a nuisance. also it will continue to store a 28a0 code. i have replace plugs,new top pan and gasket and oil cover housing gasket was leaking 2 years ago/new belt and pulleys. BTW,what is the high pressure fuel pump pressure suppose to be at idle i m wondering..?? the thing is, the vehicle is working fine and no misfiring or feel of anything wrong when i drive it for hours on the highway, just that cold start and the 28a0 code nuisance.

Sir, what Are your thoughts and or your suggestions on this nightmare light?? ty in advance Sir. .@@victormanuelparraexposito2819
I am going through this on my 13 x5. The tentioner pulley went and the belt shredded, took out the oil control valve next to the crank pulley, then wrapped around the crank pulley and ate the crank seal. Where I'm at now is i just got the old seal out. (What a pain) but the small tip of a seal puller broke off and went inside and I'm not seeing it. I'm also hoping there's no belt shreds in the motor either. Any advice?
Sorry to hear you had this failure. I have some videos that may help.
To try and get the broken piece you should remove the oil level sensor and fish around with a magnet. Hopefully you can get it and not have to drop the oil pan.

My car is having a long crank before starting with the code p112f being the only fault code. I assumed this was the hpfp, but could it be a valve cover leak that causes this code and the long start?
This code could be an air leak but normally mixed with a long crank it makes it more likely the high pressure fuel pump.
I am having this same code..
(28A0 ; 101F01) original problem was dead battery. After i replaced battery and did battery registration car drove nice. Then next day my wife bright out youngest to school and when waiting in car rider line idle started surging. And above code set. I just tried the 15 (20) minutes of idling in park with purge valve electrical connector unplugged. Going to reset code and drive it… was wondering.. once i reset the code, isn’t that going to clear adaptions when i clear code?
I hope this issue is fixed for you. Normally you need a scan tool that can reset the adaptations. This is stored in the DME engine control unit. It resets them to zero so it can then relearn the mixture adaptation.
I have a N18 mini cooper, initially had 3 misfires with 2 low compression next to each other. With this in mind plus a 28A0 it’s almost certainly an internal issue with the engine being ticking bomb huh? Practically pointless in trying to diagnose other issues right? The cars runs pretty decently with some rough startups when cold and random jerking when going ~60 miles uphill.
Hello, Anything like this you want to do a cylinder leakage test. It could be a head gasket issue or valves not sealing. Some items are repairable while others would require a head replacement or engine.
I have this code but have a knock between 2 to 3 rpms. Smooth as silk at start and over 3k rpm. I dont know what this is. I have code p112f no other codes.
Sorry to hear that you have a knock sound. That is a common failure from the rod bearings. I would have the vehicle checked and you may be able to save the engine with replacement rod bearings as long as there is no internal damage.
@@AskTheCarExperts they confirmed its rod bearings and engine is on borrowed time. I dont have the money to fix it. This will ruin me for a while.
@@AskTheCarExperts i cant find a place that will replace bearing with a knock. They want to be 100% sure it will fix it. I might try to do myself.

Hello, The exhaust back pressure sensor is a common failure. I have not seen that many turbo's fail. A knock from the turbo seem like an odd symptom. I would get a second opinion on that.
Where is the part located for adaptation procedures on the N55
@@camerionjackson671 I would want to kno too
Hello, I just changed my hpfp back to oem. Could that be the reason I have the code? So should I just unplug the purge valve and idle for 15 mins?
Changing to an OEM HPFP should not cause this code. An air leak or if there is any drag on the engine this code can set. In some cases the HPFP can cause some drag or a problem with the cylinder head. But to do the purge valve adaptation reset. Clear the engine adaptations with a scan tool. Then disconnect the purge valve so it cannot activate at idle which would richen the air mixture. Then idle for 15 minutes. Clear the codes and recheck.

Hello, Did you replace the eccentric shaft and the valvetronic motor? Usually you have to replace both items.
@@AskTheCarExperts no. i replace only valvetronic motor, eccentric shaft was in good condition, now valvetronic works, no errors, but i think it needs normal calibration, not that fast thing that this guy did. cause this error (28A0) came imidietely after valvetronic start working.
if car have vacuum leaks, this error would be before valvetronic.
thanks for response
I have the same code but mine is pressure too low. Any idea, smoke tested and have no boost leaks
Boost pressure too low can be a consequential fault or a direct fault. It could be the turbo itself or a control feature of the turbo such as the EPDW or vacuum supply if applicable.

Hello Nicolas, I hope my video helps you solve it!
Hi mate. hope you are doing well. I have this error code ''21A02D Combustion Control Idle Irregular- Permanent'' it runs rough or hesitate when accelerating. Any suggestion what should i do?

Hey car Expert I’m Terrance I have a 2011 F10 with the N55. I have to codes I can’t seem to get ride of. 101F02 throttle angle - intake manifold pressure, correlation: limit exceeded
104302 absolute pressure sensor, intake manifold, plausibility, caster: pressure too low. Any help of guidance would be greatly appreciated.
I would start with the two pressure sensors. But one I had ended up being the mass air flow sensor. Smoke test the intake and valve cover first and fix any air leaks.
Hi I got the same code in my 550i F10 N63. 101F01 and also 118401. Can you make a video about these if they have something in common or is the same problem maybe?
Sorry to hear that. One of the most common causes of this fault code are unmetered air leaks. One of the most common spots for an air leak is right where the fresh air pipe goes into the turbo. The seals break down or the whole tube can be loose. I would recommend a smoke test of the system to see if there are any leaks.
@AskTheCarExperts i have an ActiveHybrid3 N55, had an ongoing fault of 2202E3 and a leaking VGC (no CEL/car running strong), replaced the VGC (not the valve cover), after the car was put back together the CEL came on saying lean and implausible reading from MAF.
Found an inlet pipe to be broke (believe the one you mention here), replaced.
Drove the car for 15 mins and the CEL came back - 101F01 - throttle valve opening angle, absolute pressure, intake pipe, comparison pressure too high
118001 - Mixture control, Mixture too lean
118401 - Mixture control, Mixture too lean; large deviation
Please help / any ideas? 😂😂

I could be very grateful for the information please thank you
Hello Sebatsian, I would be happy to give my thoughts on these codes. Air mass issue - smoke test the intake. Air leaks are common at the crankcase hoses and the fresh air intake pipes to the turbos. Rail pressure sensor stuck -- replace the sensor. High pressure plausibility - do the sensor first and recheck. High pressure pumps are also common to fail. Cat efficiency fault - failed CAT often due to leaking injectors. If you find a broken down CAT via inspection via borescope replace the injectors as well as the cat on that bank.
Heyy so I definitely have the code 28A0 , my x5 smokes sometimes out the muffler pipes when driving sometimes and the power isnt always there , would that be because of the value cover gasket ? Or do i just need to change the fuel pressure sensor ?
Hello, Smoking out of the tail pipe could be quite a few things. If you have air leaks it could also be running rich. I would recommend a smoke test of the intake to start.
@@AskTheCarExperts thanks i will do that this week . If i have more questions ill be back 😆
Have you seen a 2b55 and 2b54 (intake and Exhaust Vanos uncontrollable)?
* 2d55 2d54
Justin, It was great helping you solve this problem. Thank you for reaching out to me and I really appreciate the tip!
Ещё версия есть . Нужна хорошая притирка посадочных мест клапанов
Interesting. I have not heard of the valve seats causing this issue.
What type of labor would you
@@DoradoDevOps Hello Eduardo, What labor info are you looking for?
Hy my name is mduduzi from south Africa please help im have a BMW n55 e90 335i 2010 my car stall like cut power while driving
Hello in South Africa! Sorry to hear you have this issue. Have you had the fault codes checked?
Thanks for the response but not codes but code which There are codes when it cut out and you clear them and Neva came back but now I'm getting the DME relay code because when you put your foot down it drop the throttle and that is wer you can have the DME relay code
🙏
Does charging the battery also triggers the fault code ?
Charging the vehicle battery should not create any fault codes.
