I jus bought a 1996 E300D,About a 3 weeks ago we had the check engine light came on but had no noticable difference in the operation of the car but immediately called our local MB dealer and took it in . The diaganosis was the #2 glow lpug was bad.I work in construction and occasionally work on the equipment in the winter and whenever we replace one glowplug we replace them all. when I asked the dealer to do this he laughed and said that they Ohm test the plugs and that they were fine. Last week we had the same signal come on returned to the same dealer and he told me that # 6 was bad,Needless to say this upset me for now I had to get the car back to him and pay the tech to do the same thing he had done just 2 weeks previous plus it kind of shook my fauth in the dealers Service manager. Well I bought the parts from FASTLANE and had a very reputable independent garage put them in. Here in lies the problem the check engine light it is still on. Anyway to reset it?Thanks

Nope, you can unplug the battery and it will reset. I do know this will work on early OBDII cars and it works on my 1995 C280 (with OBDII).

Just unhook the battery for a minute or two. I know there is a way to just unplug some fuses for a minute or two, but don't know which ones for your car.

Disconnecting the battery reset the check engine light on my 1996 E320. However, you will need your radio security code to unlock the radio.

Thanks David, That was the first thing my wife thought of becuase when we recieved the car from Houston (we live in the Chicago area) The battery was dead and we had to get the code. This sure is a great sight and thanks again to all of you for helping out.
