Re: UPDATE: CEL and Hesitation on C230
Got the Mass Air Flow Sensor from Fastlane (mercedesshop - THANKS PHIL!!- The dealer wanted $500 and I got it from him for $300) and in 5 minutes swapped out the old one.
The car is PERFECT.
The whole problem was due to the MAF sensor.
The fault code indicated 02 sensor, but as it turns out a bad enough MAF sensor will set an error code indicating 02 sensor problem as well.
