A friend of mine has a 1995 C280 and the check engine light comes on sometimes. She said it comes on and stays on then it goes out, sometimes it goes out for a week and then comes back on. My question is how do I check for codes on this car, or is there something else I should check? Thanks.

need to pull diagnostic codes from 94 c280

Thankyou.

My 95 C-280 check engine light is on constantly. The EGR valve has been replaced along with the engine wiring harness, plugs, wires and spark plug connectors. Car runs fine and displays no other symptons. Any suggestions?

Get the codes..........
