I just changed engine oil but..
I tried everything to get rid of service D on the screen.. my reset button doesn't work or module is broke? I can access to most computer system in my e320, 2003 model, but i cannot reset the service.. service tech told me my service module is bad.. is it possible?
I follow Sticky's service call.. but my computer won't take to where service section.. If i presss the reset button for 5 sec, it goes back to out side temp. please help..
