change search query for any other parts, remove +cylinder+head+ and add the part. Ideally, you should have the service manual.

Under the hood.

No just keep cranking, it will start eventually, just takes time.

YOU NEED TO ERASE TROUBLE CODE WITH A CODE SCANNER.IF CODE HAS BEEN ERASED AND WARNING LIGHT STILL APPEAR MAKE SURE ALTERNATOR BATTERY POWER FEED WIRE AND CHECK WIRE COMING FRONT SAM CONTROL MODULE WITH FUSE AND RELAY MAKE SURE WIRE IN PLACE TIGHT NOT DAMAGED. CHECK MAIN FUSE IN FUSE BOX THAT SEND POWER TO STARTER AND ALTERNATOR.

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

hi, unfortunately this is one of them how longs a piece of string things, you could purchase a code reader reset the error code but, what you have to think of is what caused it to do it in the first place, accelerating to hard should not cause an error ( i do it all the time in my car lol ) but it might be related to the 02 sensor getting to much unburnt fuel passing it which would cause the engine light to come on, though if the car is running as normal i doubt that will be the issue, i would myself on a car like that take it to the main dealer and get them to check it out, as buying an inexpensive code reader might not cut the mustard with this one, and parts being as dear as they are for merc's i would play on the safe side, spend a few bucks to save a load...sorry not much help
