Hi,
Does the '97 A4 1.8T have an idle control valve? I've searched the forums, but only see info on the 2.8 engine.

My A4 won't idle unless I manually give it some throttle. Previous to this problem, and for as long as I can remember, the idle would drop to ~500 then return to ~900 when returning to idle...even if the throttle is pressed slightly, revving it to 1100.

Thanks!

yes it does, and book time is roughly .5 hrs.. so it should be relatively easy to locate and replace. hrm.. do you have any other codes with these issues?

 

Unfortunately, I don't have an OBD2 reader.

I just spent an hour trying to locate the idle control valve with no success - 'course, I don't have a picture of it....which makes it difficult. I'd imagine it would have at least one hose and an electrical connector, etc.

Does your repair book describe the process to remove and replace the valve?

If I can't find it by monday, I'll go to the dealer and have them print out the parts description of it.

Thanks,

Greg
