| Crankcase (pcv) problems |
The contact owns a 2000 Mercedes Benz Slk230. While driving 15 mph over a railroad track, the engine shut off. The dealer stated that the failure may have been due to the crank shaft position sensor, cam shaft sensor, mass air flow meter, or an electric ignition switch ring. The failure has not been properly diagnosed. The current and failure mileages were 65,000.
Cars engine shuts off suddenly without warning. Most instances occurred while car was in motion. The electronics stayed on but no engine operation at all. Sometimes the vehicle would restart with a slight turn to the left and then right or turning off all the way and restarting. About a third of the time the car would not restart for 5 to 45 minutes with one occasion lasting over 2 hours. Most recently the engine shut off 4 times on a 90 mile trip. The last of the four failures occurred as I was parking and would not restart until later. After taking the car to 2 different dealerships and neither finding a problem, the crankshaft sensor was replaced on speculation that it could be a result of a similar failure on other Mercedes Benz engines.
