Hello, W210 E300 Turbo Diesel, When started this morning, the check engine light & glow plug indicator lights came back on when the enging started and was running.
Any help would be welcomed.
Regards, Lgriffi

 

plug in an ODBII reader to get a better idea what triggered the light.

 

my '00 e430 CEL just came on this morning as well.. it just hit 130k miles, what could be the possible problems? I just bought it, previous owner said that the O2 sensor should be going bad soon when i got it.. how much would that cost to replace? Im new to ME/BE after driving BMW/Audi. Do i need a special OBDII reader like Das Xentry or aynthing like that?
