300e Check Engine Light w/Transmission in gear
Today my car starting doing something new. When I put the car into any gear from park, the check engine light goes on. If I move it back to park it still stays on. The transmission seems to be operating as normal, but, I'm paranoid now to travel any long distances. I don't think it's a bad bulb since I didn't have the lights on. If it is not something simple I will have to bring it in to an expert MB mechanic. Where do I begin to diagnose this?
Purchased the car two years ago.
No major repairs.
