Hva betyr feilkoden?
A collective code for fuel adaptation faults on bank 2, set when one of the underlying adaptation codes for bank 2 is stored in two consecutive driving cycles. The code is always linked to one of them, so it is the underlying fault code that should be troubleshot.
Mulige årsaker

Hva du kan gjøre
- 1Troubleshoot the underlying fault codes for adaptive lambda regulation on bank 2 first and fix them
