Hey guys
Im sincerely frustrated with this car.:censor: I have been dealing with issues since purchasing it last year and have not yet been able to identify the real culprit.:ben:
INPA is spitting out codes:
202 Lambda control block Bank 1
227 Lambda cotrol tolerance Bank 1
240 Cyl. 3 Misfire
241 Cyl. 4 Misfire
Adaptation values are below 0.20. Currently 0.11
Multiplicative is at 0.00
Sometimes the misfire spreads to cyl. 5 after a while of driving after clearing codes.
I have replaced the CCV system, Fuel Pump, Fuel Filter, Smoke tested for vacuum leaks and sealed everything, Replaced DISA Gasket, and Replaced ICV gasket.
Coils and plugs were rotated to subtract from list of possibilities.
There are only a couple more things I can think of that it could be:
1. Fuel Pressure Regulator- Which I think if it was at fault would be causing a random misfire not just in the center cylinders.
2. Clogged Fuel injectors- also dont believe this is the problem, due to the only 120k on the car and maintenance records show maintenance replacement of fuel filter. Also fuel injector cleaner has been run through the tank several times to no avail.
In need of some informed advice of where/what I might be missing.
I was a tech for years and haven't been frustrated by a car as bad as this since my last experience with an 850i.:evil:
Thank you in advance for your replies.
