My 2001 ml320 has an intermittent starting problem. The symptoms are the same every time. The remote will not open the lock, once you manually open the door, the car will not crank. You can turn on the radio and the dome light. This problem seems to happen after a short drive. The Mercedes dealership has been working on this problem for 10,000 miles and cannot figure out how to fix it. The car will crank if you wait an hour or so to try and start it after it doesn't crank. I'm going crazy over this. Any help would be greatly appreciated.

I could take some wild guesses, but it would be quite simply that, and I doubt it would be all that helpful. I would be interested in taking a look at what they've attempted so far. I'd like to see all the paperwork they've given you, parts replaced, and if they give their customers a copy, the DTC readouts. Armed with this information, I could make an educated assumption that may be of some use to your repair facility.

This last repair seemed to fix my car for about 5 months, then it started all over again. Thanks for any info. Also, the entire fuse tray in the engine compartment was replaced due to this problem about 2 months prior to the repair listed above. Thanks again.

Althought the EAM can cause these conditions, it's more likely that either the transponder ring around the ignition switch or the AAM (all activity module) is bad. I'm surprised that TAC (technical assistance center) would not opt to do the AAM as well. I would take it back and have them go from there.

Thanks a lot. I'll let you know how this works out at the garage. They have the car right now.
