Thank you for the guide, very helpful.
I recently bought a 325i 3.0L with a N53 engine, 180.000km on the clock. 1 hour after I bought it, I got the yellow engine light on..
I took it to BMW, and they first said it was the 0029F3 DME: Fuel low-pressure sensor, electric. I got that replaced, but unfortunately it had these following issues as well:
002B05 DME: Nitrogen-oxide sensor, heating
002B07 DME: Nitrogen-oxide sensor, electric
002B06 DME: Nitrogen-oxide sensor, lamda linear
002AFB DME: Nitrogen-oxide sensor, lamda binary
0029F2 DME: Fuel high-pressure system, fuel pressure
I also experience uneven idle in cold start, bad fuel economy, non-smooth ride, heating fan constantly on.
I have waited almost two weeks for a friend to replace it, hence BMW would charge me around 6.000 DKK (720 GBP) to replace one single nox sensor at the rear end of the car. However, it seems he doesn't have time, so I want to replace it myself at a DIY shop.
My first question is, can you recommend I follow this tutorial I found at youtube:
I found the following part no. 11787587129 (as is stated in the service offer received by BMW) in Ireland for 270 GBP with shipping to Denmark, and it is original BMW NOx sensor. Second question, do you recommend I buy original part or is is just as good with a non-original. As I have found a brand named METZGER NOx-sensor, at autodoc.co.uk for around 360 GBP.
Looking forward to hear any of you guys replying.
All the best and hope you guys are safe
