thanks, you been a great help.

I as well justed had the same problem. Where u able to find the cause for it??????

yes, it was the cps (crank position sensor)

Should you clean out the hole before replacing the sensor, how should you go about doing that if so?

My ML320 stalled after having lights come on dash. After about 30 minutes it started. Next morning it started and I drove it about 7 miles. I noticed that as I was parking the lights wer dimly on, but on. At one point the sound to the radio went out and there were no lights on the instrument panel. I parked and when I returned an hour or so later it started, but the check engine light came on and a few others intermittently. As I neared my exit I noticed that the entire panel lit up and I could feel it stalling. I coated down the exit and made the turn by pressing down on the gas, which did not make it go fast at all. It coasted until it got to a slight incline at the end of my block, and then stopped. I could not restart it, and it would not do anything. 2 days previous, after filling up I recall the battery light coming on and then going off (the battery is new), and shortly after a few small control panel light flickers. I checked all of the fuses, and changed one that was blown, but I know now that it was for the lighter. After changing the fuse the lights, radio, and a/c operated normally. All lights are off except Check engine, and the vehicle will not crank. It clicks and then nothing. I took the battery cable off to reset, but it did not change. I've spent the day reading and troubleshooting, and I hope this is the cps. I can't get the car to anyone to have codes read, and I am sure I deleted the previous ones.

Can anyone confirm that the CPS would do this as well?

I just think your battary is dead, I would charge the battary then check the voltage at the battary it should be in the 14volt range I think. with everything on A/C, radio, head lights.

Good luck

ML430 Stalling
 

This response is to Mr. Chassis:

I have the same problem with my ml430 truck stalling out. When I say stalling I mean I could be driving it will stall and give a beeping noise. Now I can still drive, but all the lights are on the dash board are light and the engine is still running. I get to a point where I can pull over and put the truck in park, turn it off, turn it on again and start driving again. This has been going on for some time and no one can seem to resolve the problem.

It's been to Mercedez and of course they say they don't know what it is but dont repair it, but right now, I can't afford a new truck. I've done all the other servicing they suggested but this problem continues.

The gear shift sensor has been replaced but I am not sure if it was done correctly. It doesn't give a code, but now the service engine light is on.

I read your post and you seem to know what you are talking about. Questions: Do you think its worth it to have the crank shift sensor replaced again? Is there a wire that comes with the cranks shift sensor that needs to be replaced also? What is the part number? ML430 2001.

Any thing you can tell me would be greatly appreciated.
I will check here tomorrow 8/29/11 and see if there was a response. If you email me, I will call.

Thanks
