When warm it will crank but won't turn over until it cools down. Just started having the problem today. Now check engine light is on and they say it is the Crankshaft Position Sensor.
Turned over for 3-5 minutes before starting. Trick was to turn it over for a couple minutes, let it sit for 10 mins and try again once it cooled off from the first try. Usually started on the 2nd or 3rd try. Brought it to the mechanic and the Crankshaft Position Sensor Failure code popped up on his machine. Changed the part and problem solved.
Started fine when cold, but after 5 miles, when stopping at a traffic light, engine dies and will not restart.
Very embarrassing in stop and go traffic......car will start when cooled off, but replace that crank sensor ASAP.
Independent German car repair facility charged $350 to replace a $40 part in half an hour.
Will fix it myself from now on......
Same problem. $600 to repair at local dealership.
This occurred randomly and cost roughly $500 to repair at Loeber Motors
This is a very common problem on the Mercedes.
The Crank sensors fail at around 100K miles.
The sensor itself costs around $40- to 120, but it is located in a very tight spot to get to...
LH side of the engine, down near where the transmission bolts up to it, and close to the exhaust system.
Many automotive shops charge outrageous prices to replace the crank sensor....
car didnt start after i put gas in the car.. engine check came on and it was the crank sensor.. i brought a new one and had my mechanic put it in..
same as others described.
