Check Engine Light on my 2012 E350 Coupe with only 76K miles
I had taken my car to dealer for engine light that recently started appearing on my car (2012 E350 Coupe with 76K miles) dashboard. I am shocked with sticker price cost of fixing it - 11000$ and after negotiating with the dealer he is asking anywhere from 5500 - 7000$ based on whether fuel injector needs to be replaced or not. My car is running great and haven't noticed any noise or loss of power. Dealer Diagnosis suggests that I need to replace Engine Control Module, Engine Wiring Harness, Position Sensor, Lambda Probe Sensor and likely Fuel Injectors and Knock Sensors. Dealer is saying that ECU is filled with Oil. Is this manufacturing defect that Mercedes should fix it as it doesn't feel like 76K car should end up with this mess

I don't know if this issue applies to the 350, but check this thread https://mbworld.org/forums/e-class-w...g-harness.html
