Have a 2003 bmw 325I .. My car idols but it will shut off and then he won’t want to start.. I get the codes p1633/p1634/p16A0 .. I replace the mass flow sensor , crank sensor , both can sensors ,
Note that you may need to pry up the small tabs on the end of the plug connector to get it off. requires a small flat head, but be careful not to break them.
Nice vid. Gives a good idea of what to do. I tried to get a way with a ratchet but need to buy a breaker bar as it was just too much torque and really awkward to get to with the 3.0 litre. 3.0 - get the first sensor and leave it, then use the space to get the second out before installing a new 1st. Might have to move the engine cover and cabin filter box too. Maybe I should let it warm up a little.
Yes there are 2 pre-cat sensors in the exhaust manifolds and both use the same part number. So yes, the cables are both the same length. Hope it helps.
Thank you so much your tip. I love your channel. Well O2 sensor is troubled, Fault code sign is on light ? And could you show us how to replace rear exhaust O2 sensor ???
+Stevie Ha thanks Stevie. A failing O2 sensor will eventually throw a fault code and 'service engine light'. However, an original sensor with high miles can cause degraded performance over time such as poor fuel economy- but not throw a fault code. I will get to the rear O2's when needed!
I have a 2003 E39 530i. The positions of the oxygen sensors on my car is roughly the same but I think because of the different sized engine they are positioned very awkwardly. The front one would not allow easy positioning of the socket and ratchet and the rear sensor while you can see it, it's almost impossible to get your hand or any tools in there.
Thanks for the vid! Breaker bar is good for removal, but you should recommend a torque wrench (or at least a normal short handled ratchet) for tightening. Especially using a breaker bar, it would be very easy to overtorque and strip that aluminum block! Could be an expensive mistake... Correct torque is "O2 sensors: 37 ft-lb (50 Nm)" per several forum websites.
Thank you so much as I'm going to replace all 4 and the mass air sensor to as new cat fitted but light won't go off That so much buddy appreciate your message and time
Hi Dough, my 530i Bmw 2003 failed the smog test with the following codes, PO313, PO505, PO102, PO185, PO174 & PO171. Do you have videos to repair these?
Hello have an bmw e39 1998 m52 520i when on cold start the rpm goes up and down like it gon turn off if you dont hit the gas pedal and the accleration si not constant its good when the car is cold but when it is hot or driven more the accleration is sluggish not enough power but sometimes the power comes back and goes away again no engine light no nothing just not enough power it feels like the car is heavy like a army tank haha i dont know how to explain it better please help please
Fernando Flores Jr yes they definitely will affect mpg performance. But so will tire pressures and overall vehicle health, worn spark plugs. Proper weight 0w40 fresh oil.
Hey Eric! Great question. You'll notice at 1:51 the new O2 sensor has anti-seize on the threads. The new Bosch sensors come with a dab of anti-seize on the threads, ready for you to install. You do not need to buy any additional product if you use the Bosch units. I am not sure if other brands also arrive like that.
Hello i am still confused i have a BMW316TI COMPACT 2003 my OBD11 fault codes are P0140 HEATED OXYGEN SENSOR (HO2S) 2, BANK 1 - NO ACTIVITY DETECTED AND P039 HEATED OXYGEN SENSOR (HO2S) 2, BANK 1 - SLOW RESPONSE so does anyone know whare on the car this ?
I found out myself. For other ppl: There are 2 types of sensors, which differs. The two sensors BEFORE the cat are the same and the two sensor AFTER the cat are the same. Before and after cat are different sensors, they are not changeable. The pré-cat sensors are mostly defining the fuel mixture, they are the first sensor you would replace by problems or ascending consumption. The post-cat sensors are less important, and normally only replaced when an error light pops up. For European BMW-owners: Don't point too much on the ECS website for this subject, the part numbers from USA M54's are not the same as the European M54's in this case
I recommend a straight adapter for these, rather than the offset one shown here, because the straight one doesn't mess with the torque settings (50 Nm/37 lb-ft for these).
+Ukboy Uk Your E46 325i also shares the M54 engine and will have 2 pre-catalytic converter oxygen sensors and 2 post-cat sensors for a total of 4 sensors!
It is possible, but the lean codes you're seeing are more likely the result of an intake leak. Check the upper and lower intake boots for cracks. The CCV system can also cause those codes, so can a cracked valve cover or leaking valve cover gasket. The best way to diagnose this correctly is to pay a local independent BMW specialist shop about 1 hour labor to smoke test the intake system and find the true source of the leak. Otherwise it is near impossible to find... unless you get lucky and see visible cracks or tears in your rubber intake boots. Good luck!
Hey i need your help, i have a 325i 2001 bmw e46. I took it to autozone and hooked up it to the code scanner , and my car misfires cylinder 1, 2 ,3,4, &6 , i also got the code "O2 heater circuit bank 1 sensor 1, bank 2 sensor 1.I bought new coils and swapped em, my car still shakes and misfires. What do i do?
Ryan de la cruz You definitely have a vacuum leak , most likely oil leaks are causing the misfires , had 10 people who told me I was wrong ! just recently had similar issues : problem solved , I also had a bad disa valve , ccv hoses cracked which is where the vac leak was coming from . Vanos was leaking as well , o ring needed replacement , you need to do a leak down smoke test , that will help a lot to source that vac leak
Hey Daniel, thanks for the question. Yes the two sensors are the same. If you have a code for one, you can just change one. But I'd recommend just changing out both at the same time, they are relatively inexpensive especially if you are DIY'ing this one. Should bump the fuel economy a little bit as well. Thanks!
+D Boi Hi D Boi, it's not likely that smoke is actually coming from the O2 sensors. The valve cover gasket leak is very common on the M50/M52/M54 engines, and an oil leak is probably the source of your 'smoke'. The gasket leaks oil right onto the exhaust manifolds that house the O2 sensors, so it probably *looks* like smoke is coming from the sensors, but it is in fact oil residue burning off the sensors/manifold. Hope this helps!
+BIMMER ZEIT thanks for the quick reply ...I replaced the vcg and grommets thinking that was it and turned on the motor and examined closely and white smoke comes around the o2 sensor its also got gunk compared to the second o2 sensor between cylinder 5&6 any advice would be appreciated
Yes on the M54 that would be the rear sensor. I would suggest just replacing both at the same time, they are only $45 each, link in description above. Should also notice modest improvement in gas mileage after replacing both sensors.
+Fix The Bimmer I also have another question. I have a BMW 5.30d 2002 model E39. My steering wheel is very hard to move around. The hydoalic oil is checked and there seems to be enouugh inside it. Anyway to know exactly what's causing this? Also, when driving between 50-60 kms/ per hour I have some vibration and some instability along bad roads. Could you tell me what to check for maintenance?
+Turhan Uludağ I haven't heard of that 'hard to move' steering wheel problem, I would suggest having a shop take a closer look. The vibration first check wheel balance or for a bent wheel. Upper control arm bushings when worn also are notorious for causing vibrations at that speed, and stability issues over rough roads.
+CoolinKofi This applies to the M54 and M52TU engines with dual vanos. Your 1998 has an M52 single vanos engine, and does not have 02 sensors located in the manifolds like this. The sensors are further down the exhaust pipe, and are quite a bit more difficult to change. Hope that helps.
yes your M52TU is a dual vanos engine, so this video should apply. To check, pop the hood and take a look at the exhaust manifolds as shown in this video. There will be one sensor in each bank (one front, one rear).
I never had a problem with the aftermarket Bosch parts. Just make sure it says sold by and shipped from Amazon.com otherwise maybe there are fake Bosch parts from 3rd party vendors in China
who is the manufacturer of this sensor? Bosch original is never this cheap. If it is aftermarket market it should specify the manufacturer instead of using misleading misinforming consumers Bosch brand.
Bosch is the manufacturer. BMW often takes 3rd party (ie Bosch) parts and put's their BMW roundel stamp on it and charges 2X or 3X. The sensor I linked to has hundreds of 5 star reviews, it is fine. Amazon will replace for free if there's any issue with it. It's legit!
BIMMER ZEIT I’m just asking you what the actual brand is. Can you tell me? If it is really Bosch it will not be this cheap! Go and find from Bosch itself or ebay. Would you just tell me what the actual brand is?

Yes there are 2 pre-cat sensors in the exhaust manifolds and both use the same part number. So yes, the cables are both the same length. Hope it helps.
@@BIMMERZEITT Yeah thanks a lot !

I already changed the 2 top ones but can’t find the other 2 you have any idea we’re there located bro ? 2003 bmw 530i
Great vid. Correct me if I m wrong... but isnt this the M52TU engine rather than the M54?
Kon Wai Luen this is a facelift 2001 530i, it’s an M54. The 528i had an M52TU from 1998-2000.
please make a video on where to locate an 02 sensor on bmw e39 528i
Best tutorial video I've seen so far. Kept it simple for DIYers. Now, can you please teach us how to install a downstream o2 sensors? Thanks a lot!
Thanks Mark! I appreciate that. I will post that up as soon as my car needs them!
ty!

Would it be a proper tq spec even be right with that sock not being directly on top of the 02 sensor
The o2 sensor doesn't screw into the block
Correct, it goes into the exhaust steel threads. Torquing is an overrated activity and feel is more intuitive.
so,was that bank 1 sensor 1 and bank1 sensor 2 ????..i saw other video and guy says bank 2 sensor 1 is under the vehicle ??
Thank you so much as I'm going to replace all 4 and the mass air sensor to as new cat fitted but light won't go off

4? 2 on exhaust side and 2 on intake side?
Gret job! On e46 M3 is the same process??
Hi Dough, my 530i Bmw 2003 failed the smog test with the following codes,

i got a 330i 2001, so dose it only have 2 senors or more?
+VINCENT RODRIGUEZ your 2001 330i has the M54 engine just like this 530i. So it has two pre-cat oxygen sensors and two post-cat oxygen sensors.
Thank you o Damn much! I finally understood from you that there are 2- precat sensors in the front.
i have a 2009 328i bmw how i can change the ho2 sensor
Hello
have an bmw e39 1998 m52 520i when on cold start the rpm goes up and down like it gon turn off if you dont hit the gas pedal and the accleration si not constant its good when the car is cold but when it is hot or driven more the accleration is sluggish not enough power but sometimes the power comes back and goes away again no engine light no nothing just not enough power it feels like the car is heavy like a army tank haha i dont know how to explain it better please help please
Are these sensors responsible for my E39 burning gas so fast?
Fernando Flores Jr yes they definitely will affect mpg performance. But so will tire pressures and overall vehicle health, worn spark plugs. Proper weight 0w40 fresh oil.
exactly the video I was looking for. thanks
Same 2"sensor?
Would the pre cat be my bank 1&2 error on my e61? And is this tool universal for all O2 sensors for bmw?
No torque necessary?
Do you use any anti-siezing or anything else on the threads of the O2 sensors?
Hey Eric! Great question. You'll notice at 1:51 the new O2 sensor has anti-seize on the threads. The new Bosch sensors come with a dab of anti-seize on the threads, ready for you to install.

Does the Bosch replacement sensors fit in both banks or is each bank different?
Michael Yunn they are the same for each bank!

can you please give the bosch part number on both these sensors?
Ive got a 325i e46 2004 dose it have 2 sensors or 3
And like the video thanks
+Ukboy Uk Your E46 325i also shares the M54 engine and will have 2 pre-catalytic converter oxygen sensors and 2 post-cat sensors for a total of 4 sensors!
Hi, is the first sensor same as the second?
The 2 pre-cat sensors in the manifolds are both the same and are interchangeable. One part number for both.
Will bad oxygen sensor throw p0171 and p0174 ? For a bmw 330i 2001 ?
It is possible, but the lean codes you're seeing are more likely the result of an intake leak. Check the upper and lower intake boots for cracks.

I think I can do this because I tried on my Chevy but it was rusted but every BMW I’ve owned never had an exhaust rust issue
anthonyk should be ok, spray with some PB blast and let sit for an hour before you attempt. Wear gloves.
BIMMER ZEIT ok
Thanks for the video, my CEL came on and error came back with faulty O2 sensor. How many sensors are there for e39 540i M62Tu?
there should be 4 all together, 2 up stream (before cat converters) and 2 downstream (after cat converters)
Where the link for the tools guys

cwb253 if it was one bank - then try a new sensor but if sensors going at the same time could mean a dodgy MAF sensor or air leak/CCV.
The sensors are both the same? Do I have to buy 2 sensors the same?
Hey Daniel, thanks for the question. Yes the two sensors are the same. If you have a code for one, you can just change one. But I'd recommend just changing out both at the same time, they are relatively inexpensive especially if you are DIY'ing this one. Should bump the fuel economy a little bit as well. Thanks!

Remove front sensor first then rear sensor. Replace rear sensor first as well. Much easier.
Getting code p0155 in my e39, which pre cat sensor would I need to replace, the rear ?
Yes on the M54 that would be the rear sensor. I would suggest just replacing both at the same time, they are only $45 each, link in description above. Should also notice modest improvement in gas mileage after replacing both sensors.
+BIMMER ZEIT thank you for the quick response
+BIMMER ZEIT just to confirm, both sensors are known as the pre catalytic converter sensors correct ?
can I try cleaning them before buying a new one
Does this apply to 2000 bmw 528i also?
Yes it should be the same if it's an M52TU or M54
Yes, it's the same.
Very well made video
Same for 98 M3 ?
How often should they be replaced?
+Turhan Uludağ Most people replace Oxygen sensors when they fail. The service engine soon light will come on with an O2 sensor code.

Try a stub wrench
Great video I have 330i about to do it myself and I’m a girl 😻
Pretty straight forward
You need to mention why did you have to remove them did you know that your O2 sensor is running rich is that why it's white
