My mercedes ML 270 automatic diesel

You might need to replace egr valve

tork converter

Only a compatible scanner is going to turn this off.Don't try to do it yourself, as with any air bag/srs (supplemental restraint system), these units contain what amounts to an explosive charge, and if not handled properly, by trained folks, they can very easily cause death, ansd a nasty one at that.As long as the system detects a snag, it will continue to turn that light back on, even if you do get it turned off. The system does a circuit check soon after the car is started, on this system, and the only way to turn off that light is to fix it. Could be as simple as a clockspring, so have it checked. This is one of the only things that I'm not really willing to give much info on, due to the potential for disaster. Sorry, it's just the old grease monkey looking out for your safety. If you get it diagnosed, and have any questions about what you have been told, or anything like that, please feel free to contact me. Good luck!

had the same problem.was a very dirty fuel filter after getting a dirty fill of diesel.i think the epc light came on the dash and the engine just cut out.
hope this helps
barry....

That would be the turbine speed sensor.............not a cheap fix at around £450 with main dealer

check the gearbox oil level ,but their is no dipstick ,so its a dealer only job unless you can find a snap on man who sells a special tool that can measure the oil level ,

• you need a Brake safety switch replaced.This is located behind you brake pedal.it's a common problem. The warning lights will reset after a few engine starts.

oil is MERCEDES A000 989 21 03 and GO the DEALER BECAUSE YOU NEED THE TOOL FOR CHECK THE OIL IN THIS TRANSMISION

although mercedes recomend using synthetic motor oil im 90% sure that your mechanics mistake (putting to much oil in it) ruined your piston rings thats what the white smoke is all about!! oil is getting into the cylinders!! make him replace them for free since he caused that prblem im sure he has insurance!!
