P2185 p2189 help
I have a 2011 E550, and have two codes being thrown P2185 "idle speed is to high when engine is warm", and p2189 idle speed control short to ground. I can't find any information on these. Any insight would be appreciated. Thanks!

Faults for idle too high ....
This is a MAF engine right...
Idle too high means vacuum leak from... crankcase breather or a popped rear camshaft plug?
Any recent work done... intake seals?
See that throttle body is nearly clean to seal idle air.

I havent had a check engine light on, just a code stored in the ECM.

Thank you for your response. I'll look into it this weekend. I recently (2k miles ago) replaced the crankcase breather along with the rear camshaft plugs (a kit from FCP Euro). I'll inspect my work this weekend get my eyes on the throttle body.

Super late response. Yes, I did find the fix, it was related to the crank case ventilation. I replaced the vent plugs and the vent valve. Coupled with a new engine air filter, the car stopped throwing these codes.
