idle control unit location
 

Does anyone know where the idle control unit is located on an 86 560sl

Hey,

According to my sources, it should be behind the glove box, next to the fuel pump relay.

Good Luck, R.

Side kick panel, passengers foot well, above the fuse block.( IE: Right side looking forward.)

Thanks, after replacing it and the idle control valve it still idles at 1800rpm

What did you do to confirm the problem is from control unit?

There are so many things that could cause a high idle. I spent a whole 3 months working on my 1991 560 SEL, including a trip to dealer, but could not ID the root cause.

Finally, I just plug teh Idle control valve with a cork which has a 5 mm hole. This is well discussed on this forum. That took care of high idle proble for good. Plus, it costs me $0.

Over Voltage Relay fuse was the problem. 10 amp fuse and all is well
