Answer 1
I do not have a lot of Mercedes experience if you are having this problem before replacing a computer I would send both computers out to be tested. Tehre is a company I deal with here in California, very helpful and quick turn around, Fuel Injection Corporation ,2407 Research Drive, Livermore, CA 94550, Phone: 925-371-6551. Give them a call. I called them before with a Jaguar, BMW and Alfa Romeo the fellow I spoke to knew exactly what was wrong and fixed each problem. -
