AUDI RS4 B7 HIGH negative LONG TERM FUEL TRIMS
Posted: Tue Mar 31, 2020 3:58 pm
Hey i'm getting high negative long term fuel trims for a while.
The car runs fine but not performs as it should and sometimes i get this fault code fuel trim too rich.(Sometimes on both banks)
My Lambdas has been replaced 15.000km ago and carbon cleaned almost 8.000 kms too.
Anyone who can guide me where to start and what to check ?
