When it does start it wont stay idling and will stall if you let off the gas pedal. I took it to John Holtz Mercedes of Rochester, NY and they claimed that there were numerous codes from different modules but one for throttle valve actuator as well. How much does this cost for my car?
What is the part number?
What does it look like?
Lastly how easy is it to replace?

I plan to do it myself if I can. The dealer wants $2400 for it.

Thank you in advance for all your help. I did search the forum but did not find the picture and how to remove info for my car.
I've not seen rough idle due to a failing ETA (Electronic Throttle Actuator) but there's a first time for everything. The history of my ETA and others is contained in MENU#24 on my pages.

Also get the codes that were read to help you diagnose the 'complete' picture for your car. We can better help you.
