My wife's 2009 ML350 is having some weird problem. I've taken this to the local Merc dealership, where they said they couldn't repeat the problem and charged me $280 for the privilege.

So I'm going to try and diagnose this myself before getting a more experienced Merc shop involved. If anyone has had a similar experience and solved it, or has suggestions on anything I could do myself on this, I'm all ears.

Here's what is happening:

1. Car runs fine, starts fine, can't complain
2. When getting to destination and turning off the car, it shuts down the engine just fine.
3. Electronics (in dash, lighting Int/Ext, etc.) all won't turn off. Normally these will "time out" after about 10 seconds, but in my case they never time out.
4. In order to force it to turn them off, you have to start/stop the car about 8 times and eventually it will turn off
5. One interesting thing that I noticed is that if I take the keyfob away from the car so that it is out of range (about 20 yards), then I can press the Start button once (without actually starting the car) and it turns off correctly.

Thinking that maybe the keyfob is faulty, I've ordered new batteries and we have a spare one, so when they arrive, I'll test this with a different keyfob. But as of writing this, I can't do that as the batteries are not here yet.

Anyway has anyone had similar experiences with theirs before? I'm super curious.

Thanks

You are in the wrong forum. This is W163. You need W164.
