I have an '86 Audi 5000S 2.2 turbo. 5 cyl 5 speed. It cut out & died, while I was driving. Wouldn't restart. I found a vacuum hose broke that went to the underside of the intake, I think it went to the fuel shutoff valve? anyway it now starts and runs but it won't idle properly, it seems to- the only way I can describe it is "carbon up" ( like on the old carb. models). I have changed plugs, wires, cap & rotor. did a compression test. It ran great before it up and died. I know Fords but this, especially with a CIS system is totally new to me. Where do I go from here? Is the next step checking the cold start valve and warm up regulator?
Oh also I heard that with a CIS fuel sys. you have to bleed the system after opening it, like on a diesel. Is this true? If so where are the bleed ports and what order do I bleed them?
I HAVE ALREADY bought the book but sometimes it seems kind of vague. I belong to Alldata also but you would have to already be a certfied Audi mechanic to use it very much. I sure would appreciate any suggestions. Thanks Cherry

 

I know this is unrelated, and I can't help you. I can't even get my air box out on my 1989 200. I figured since you have a 5000 you might be able to tell me. If not, that is ok.
