Re: A potential nightmare averted… thank you Crossfire Forum! Crankshaft Position Sen
Dollface,
Changing the Crank Sensor was a good move, with 74k miles
it was time for it to be replaced. But your symptoms sound
more like a RCM ( Relay Control Module) problem. Or
have you already replaced it? Car turns off.. either at a stop
or while moving, lights on dash stay on.. will start right back up when you turn it on again. In my opinion that sounds more like a RCM starting to die on
you .. If you already replaced it then the crank sensor should probably fix your problem .. if it continues to do it .. then the RCM will be to blame! There is a post here on the forum about that problem give it a search .. From experience I can say that a bad Crank Sensor will not allow the engine to start right back up again it will just turn over a few times and eventually might turn back on and in most cases it will also turn your check engine light on
I think your RCM is about to go out .. If you're here in Houston I can send you a # of the Mercedes Dealer Parts representative in Austin where I got mine at least 80$ cheaper than any Mercedes dealer here in Houston. If I recall the Local Mercedes dealers were asking about 210$ for the part and I called Austin and got it for 140$ .. The part is really simple to replace, probably as simple as replacing a light bulb in your home.
PS. The seat belt question was already answered by RL67037 .. follow the link he posted to deactivate the chime, but remember that if you ever pull fuse 35 from the fuse box in the engine .. It will reset the chime deactivation and you will have to do it again, no biggie just an FYI
Take care!
