Starting problem on my ML320 (1999). When I after use my ML (hot engine), engine off then re-start again – “the problem was the key switch turn to start position, the key & the starter can not release respectively.�

After 1 ~ 2 hours later (engine cool down), it start up normal & smoothly.

Anyone have same symptom???? And how to solve it.

Not sure about the "starter can not release" statement, but I had a problem with the engine not cranking when hot. It was intermittent at first, then suddenly the truck died one day on the highway. It was the crankshaft positioning sensor. I'm not the only one this has happened to. Is you engine cranking, but not starting? Is your starter staying engaged? Can anybody else help?!
Good luck,
Roger

Mercedes has an electronically controlled starter circuit they call “TouchStart�. In order to start the engine, you only need to briefly turn the key to the start position and the system will continue to engage and run the starter until the engine is running. IOW, you don’t have to hold the key in the start position to keep the starter engaged. If there is a problem with spark or fuel delivery that prevents the engine from running, this same system will continue to run the starter for some period of time until the ECM decides the engine is not going to run and then it will disengage it.
