love the perfect lighting, short and relevant comments and real life experiences (not everything goes smoothly ;-). Very tidy and professional compared to most other videos, Randy deserves more subs / credit for this!
Great video, it was very informative. If you look at the video at 3:11, the reason that the crows foot and O2 sensor tools "didn't work" is that you are actually trying to tighten the sensor instead of loosening it. When you place the adjustable wrench, you are actually turning the sensor in the correct direction. Happens to the best of us - cheers!
This is an extremely well done video! I agree with all the other comments - great lighting, camera angles, and nice wide angle. You may just save me a couple hundred bucks!
Thank you so much for this video! I think your video is the first I’ve seen in replacing the rear o2s! Thanks again!
you’re welcome 😊
@@randysdiy will this be the same for the n54?
I wonder the same for the n54... Would it be the same? I need to replace both post and pre cat sensors
@@IvanIvanov-zm1ot hey bro nah it’s easier for the n52 motor like shown in this video. For the n54 it’s way harder cause of the location of the o2s :/ I managed to replace them without removing the downpipes but it was a pain to do it.
Very detailed and through diy! Me and my e90 thank you 🙏🙏
you're welcome and thanks for watching
Im sure these bmw designers sit down and try and come up with the most difficult and maximum variation of connector they can think of just to make our lives hard. Thanks for the vid - ive now seen how to separate them! :)
That lift is awesome
Thanks a lot man, although it was a little different in my car your tips helped a lot.
Well done.
Got mine to do. Looks quite fiddly. I might just pay a shop to do it. Must be satisfying when it's all done and you are lowering the car back down 😊
Wish I would have watched this yesterday. I tried every fricken tool I had except for a small adujustable wrench! I've about destroyed that sensor trying to get it out! Hopefully I can just turn them off in the computer!
I don't know how you have that space on the O2 connection to downpipe on bank 2. I have less than have an inch
Best explanation thus far!!
Excellent DIY Video!
Hi nice video. Is this the same process for my 2006 BMW x5 E53 ?
So if I don't know when sensor goes to which connector, what should I do? Mine were broken off, caught on something. Thanks for help Randy.

at 3:10 for the bank 1 sensor second tool it didn't "work" cause you were tightening the sensor instead of loosening it
OMG! i just realize that…my bad 🤦♂️ first time i was using that tool, i got confused the way i was turning. thanks for the correction 👍
I notice that myself thanks. I thought I was going crazy .I watched the video over and over saying to myself he's tightening that bolt .But still a great video .My sensor looks easy bank 2 sensor 2
How long did this take you to change? I just got both of mine replaced and the shop is trying to tell me it took them 10 hours.
Where you buy the gloves ?
Hey wha is the name of the music jajajaja . Good video .
If I don't have a Scissor lift that lifts the whole car up at once can I just use jack stands on the front of the vehicle to get to the downstream oxygen sensors ?
Yes I just did it. I suggest going and getting a 22mm and a adjustable all I needed for mine it is very tight though on just jacks.
Would this work for Awd as well ?
Wow very good job thanks
Very good video This is something i 'am doing this weekend.One question? It looked to me that you were tightening the one that we're trying to unscrew bank one. I could be wrong
i know, my bad 🤦♂️ i was a little confused. i was turning my tool the other way around instead of loosening it
is it just me or you were turning the second sensor the wrong way? thats why it didnt work?
Nope, he did turn the wrong way.
Are they the same sensors? Or they both different
Awesome video.
I’m getting 2c9c and 2c7c oxygen sensor codes on my 08 e90 328i, is this it?
(Catalytic converter upstream oxygen sensor heater: activation) (catalytic converter downstream oxygen sensor 2 signal)
For all E90, the O2 sensors are installed like this and should be replaced at the bottom only? Isn't there any model that the O2 sensor can be replaced from the top side? I saw the connector clip is located near the valve cover for such model.
There are four O2 sensors total...he replaced the two sensors after the CATs(Sensors 2 of Bank 1&2)...the two accessed from the engine bay are(Sensors 1 Bank 1&2).
@@tysoncross1120 what is responsible for lean error codes. If I bring to a shop what should I have them replace?
Nice tutorial bro..
Where did you purchase that home garage lift please ???

@@randysdiy which model did you choose ?

What the bottom shield piece you remove? I can’t tell from the video
Hello Randy,
For bank 1 were you getting the p0420 code before changing?
Hello! What symptoms it had? Any codes?
Thanks for the video but I am a little confused are these two sensors located in the front of the car or the back of the car
front under the car
Can an oxygen sensor be faulty without reporting an DTC? What is the best way to test it, can it be cleaned maybe?
I have problems on cold start for a few seconds the idle is rough, and afterward everything is good i would say. All glow plugs are changed and the relay too.
The car is BMW E91 LCI 318D 105kw 11/09, it has only 1 oxygen sensor I would say only on the DPF, next to the temperature exhaust sensor and the pipe for pressure sensor.
Thank you for the answer in advance.
Vamos solenoid
Do you know if the post cat O2 sensors for a 2009 750i are in the same location?
What code did it give you? My e99 fails the inspection with code p2098. My scanner only tells me bank 2 but doesn’t say sensor 1 or 2. Are they all the same just different lengths?
I have the N47 318d e91 , I'm getting the code 447b oxygen sensor but doesn't tell me bank 1 or 3 and so on so how do I know which , I'd appreciate any help if anyone can answer
Is this for the n55 ?
At 3:28 that would have worked but you tightened instead of loosening it lol
i know 😂
QIK question so are they tha same sensor tho
how many oxygen sensors am i replacing again
Thought the o2 sensor was on top of the engine
so the tool isn't really needed to remove the sensors?
Do these parts fit 320i E90?
Is this open bank 2 sensor 1 ?
What is the hydraulic Jack your using
www.quickjack.com
Is the 2 O2 sensors the same for bank 1 and bank 2
I'm trying to find that out, did you ever find out if they are?
Is this a BMW 335?
11:06 song name?
Beat at 10:30?????
Be careful not to break the tab.
Goes right ahead to yank it off forcefully. Lol.
You were tightening it with the crows foot, it would’ve worked
Is this bank 1 sensor 2?
I believe they’re bank 1 sensor 2 and bank 2 sensor 2, both downstream
Where yuo Buy te hydraulic
Nah this nigga to comfortable hitting it wit tha hammer 😂 I’m over here struggling
you was going the wrong way woth the ceows foot
It’s better change the 4 sensors in one time .
Second sensor...you are trying to open in into the wrong direction lol
Can a bad O2 sensor cause the engine to misfire on two cylinders?
What car you have ? If it’s a 335i a faulty o2 sensor can make it misfire on 3 cylinders
@@TsGSnipee i have a 318i n46 engine.. umm I see, I didn’t know an o2 sensor could do that 😨
Então problema na minha 120 n46 , deve ser sonda pré , falha dois cilindros
Those ingenieers are so dam to make an engine like this . They find not solutions instead they look for dificulties and make a killing in service and repair etc .
You were turning the wrong way
