unable to find my Idle control module, I got a 1993 500e and my engine warning light stays on, does any one know the location of this module...and also who sells it besides the dealership...


thanks
roger

The system uses an electronic accelerator...computer is located in the computer box at the RR of engine compartment...doubt if the computer is the problem!

Just what is the problem? Has anyone with MB scanner read codes from EA/CC/ISC computer? What codes are they getting?

IS the check engine OR the ASR lamp on?

...is in the black box located where the battery would be in the engine compartment. Upper left corner as you look at the engine from the front of the car. It may well be the problem as I just had to replace mine. Same symptom, the check engine light stayed on. Dealership pulled the code for a faulty MAF sensor, which I replaced. As soon as I left the dealer the light came back on. Dealership pulled the code for faulty TBA. Replaced that twice and the same problem came back. Dealership said they didn't know what else to do. Took the car to an independent shop where they checked each of the other components that could cause a fault. Narrowed it down to a faulty module but couldn't say 100% that was the problem. Found a used module and problem solved.

Point of this story is that some problems on this model (mine was an E420 M119 motor) are difficult to diagnose and you may spend many $$$ before you get to the root of the problem which wasn't diagnosed by a trouble code.

Try Potomac Auto in Frederick, MD and ask for Pat. I believe their website is pgauto.com.

Good Luck!

I'm with Doc - there is no idle control module per se on your car. We need a little more specificity here - what engine warning light?

thanks for the great response from everyone.....

before i start ordering parts, my mechanic and i were trying look for the overload relay for my 93 500e was unable to locate it.. does anyone know the location of it.


thanks in advance

You're not going to find it - doesn't have one.

according to the repair manual its supposed to be located near the black box modules in the engine compartment...if you say it doesnt have one ... i'll stop searching for it....

thanks
