BMW - 4B06 - Set Zero Adjustment Cylinder 4 Injector - 2009 335d
I started getting this CEL error recently, seems to reoccur every 150-200kms.
4B06 - Set Zero Adjustment Cylinder 4 injector.
I have a 2009 335d with 200,000 kms on it.
Had a lot of work done under warranty.
Last year I had the following done:
- Replace all 6 diesel fuel injectors
- Carbon cleaning
- Replace intake manifold
- Replace Engine Head
No issues since last year and 20,000km+ until couple of days ago.
It seems this error is probably related to having the DDE replaced now.
My question is that I don't notice any issues when the CEL comes on, do I really need to fork out 2-3K to get the dde replaced, or should I juts run it as is.
Any thoughts would be appreciated.
