ERROR Self-adaptation of mixture formation for enleanment at idle below the limit
I have an issue with my CLK 63 AMG (non BS) and we have trouble to manage it.
A coupe of month ago it appears (no error with Stardiag) that my seals intake had leaks.
My workshop changed them and cleaned my intake. After that an error appeared (stardiag)
- 0750 Self-adaptation of mixture formation for enleanment at idle for the left cylinder bank is below the permissible limit. (P2190)
The workshop did the job again thinking it was an error during previous job.
But after this, I found my benzine consumption higher and with Stardiag It appears 2 errors this time :
- 0746 Self-adaptation of mixture formation for enleanment at idle for the right cylinder bank is below the permissible limit. (P2188)
- 0750 Self-adaptation of mixture formation for enleanment at idle for the left cylinder bank is below the permissible limit. (P2190)
We tried to reinitialize Autoadatation of idle and of gas actuator, but without results
I have still error on both right and left (sorry my Star is in french)
I tried to adapt the calculator (ME 9.7) (fuel flow) and it was better but I still have an error for left side
I don't know where to search.
Can it be only a question of calculator adaptation/correction or a matter with the seals or something in the intake (gas actuator seals ?)
If you have any idea do not hesitate
Best Regards
