[W126 Coupe] High Idle with ASR light on

[gary peck]

Hi Rob

Install a new OVP Relay its located under the hood near the firewall has a clear plastic top with a ten amp fuse 2mins. to change. There are ways to take it apart and resoder the chipboard and yes it may only be the fuse I've gone both routes in Canada the relay is $139.00 still the best bet, just pull into a dealership I'm sure they can pull and plug for a test and/or pull and plug one from a friend that has the same one.

  Hi all

  I have the occasional "High Idle (1500RPM) with ASR light on" problem. 

  I remember reading about this many years ago on this list - so now it has happened to me. The tech notes on the website dont specifically deal with this combination, so I am wondering if I have another problem.

  Anyone remember the fix ?
