I'm currently getting a Check Engine Light (CEL). After checking the codes, the code scanner gave the following values.

P2016 Self adaptation of mixture formation from bank1/2 of cylinder is at
P2085 max/min limit at part throttle

I cleared the codes and drove another 5 - 10 miles and the CEL came on again with the same values.

I'm new to the M112 (V6) CLK 2001. I understand the Mass Air Senors don't last long on the w112 engines.

Are these error codes normally the result of bad MAS or should I be looking somewhere else?

Thanks,
Russell
