The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.

Mercedes-Benz CLK430 Engine Performance Problems Due to Crankshaft Position Sensor Failure
Mercedes-Benz CLK430 Problem
Average Mileage: 107,146 mi (57,000 mi - 137,134 mi)
My vehicle would start and was able to drive about 1/2 mile before I lost engine power. The vehicle would not start until the engine cooled. I paid $338.00 to have a diagnosis on the vehicle and replacing the crankshaft position sensor.

still working to replace crank case position sensor, bolt holding sensor is under sensor, with heat shield making difficult to remove, car runs like new when it does start, hope I can get that sensor out.
