Help!!! Lean Code P2179
Help! Dealer has had my 2002 745 for 6 months and can not fix.
Codes P2179 and P2177 Lean both banks.
Dealer has replaced the following:
2 O2 sensors (pre converter)
various seals and o-rings (after smoke test)
They dont know what to try next. Changing oil and air filter today.
Any ideas would be greatly appriciated by me and Dealer!!!
I want my car back!!!
