I hope someone can help me with some info. My wifes C220 has the Engine Fault light on. The owners manuel says it is caused by either constricted injector or by an emmisions control device.
The engine idles to smooth and pulls to well for a constricted injector. Can anyone advise me the most likely part in the emissions control system to replace. I sure don't want to pay the local Mercedes dealer $104 per hour.
E Mail me at if you can because I will be at home vacationing for the next two weeks.
Thanks to all!!!
