I cannot get the trunk of my 1987 5000CS Quattro open. Neither key will turn the lock cylinder. I have gotten it open in the past without much trouble, but it appears to just not want to turn now. I am relatively new to this car, so-- how does the central locking interact with the trunk release?...

In 20 years I never replaced the Original Oxygen Sensor and the car recently flunked the California Emission test by a small margin. I am debating whether I should get the higher priced OEM sensor or one of the cheaper Universal Sensors, Any input would be appreciated. martino-

It is hot here in California and I am tryng to fix my 1987 Audi 5000 Radiator Fan Problem: A. It only works with either the airconditioner or heater turned on. I am looking to find the various relays and thermoswitches, but my Factory Benley Manual is of not of much help. Does any know what...

I think it finally happened: While driving, the engine suddenly stopped without any warning whatsoever! And the engine did not restart, slow turnover, sounded like a battery getting weak. The camshaft does not turn anymore.

Question: The Audi 1987 5000 takes a special Audi recommended Pentosin CHF 7.1 Mineral Oil for the steering rack, etc. When the seals are leaking, has anybody ever found an additive to improve the situation, instead of replacing the entire unit?

1987 Audi 5000s Coolant Leak.. Recently, my 1987 Audi 5000 needed the upper radiator hose replaced. (exploded). After changing/flushing the coolant, there was still a loss somewhere. I finally discovered the problem and it seems to be located under the dashboard.

I have an 88 audi 90 and the damn idle is bouncing up and down about 20 rpm and sometimes 200 rpm. I have cleaned out the ISV and put some new clamps on hoses to seal up any vacuum leaks. If I rev it up it will then stall after i let off the throttle...... I am getting a little bit frustrated......

Hello all: I tried replacing the starter on my 1988 Audi 90, understanding that it is one task that you can easily perform. My buddy and I looked under the car and could not see or feel the other bolt of the starter. (2 bolts of the starter). My Haynes book shows a photo that both bolts should be...

I have a 1988 audi quattro and i have changed the fuel pump and filter, but i have a problem with it when i try to accelerate. It seems that it starts to happen about twenty minutes into theride. Also the pump sounds really loud. Does anybody have any suggestions?

I'm getting one! And am tremendously psyched and needed to tell someone who cared. It's a manual--rare find! Only 70k miles on it. I'm giddy as a schoolgirl! All it needs are new tires (so far as I know), it's everything I want in a vehicle and the first thing I'm going to do is upgrade to 16"...

I have a 1988 audi quattro and the passenger side window stoped woprking, so I took out the hole driver side control block from the driver door, and was messing around trying to see if i could hot wire it. well, something sparked, and then none of the windows or sunroof will work. I called an...

I've been trying to fix this problem for over a year now... When I try and accellerate it feels like something is holding my car back and will stutter/surge (the brakes have been checked/replaced). The problem seems to get better after warmed up a bit. Here is all I've done to try and fix...

I am going to try to fix the blower motor in my 1989 Audi 90 Quattro, along with a few other bothersome details that come when you have 237,000 miles on it. I will try to replace the blower motor, dash lights, starter and headlight units. I have found some parts on ebay, there are none...

I've looked through as many old messages as I could but my problem hasn't quite been addressed. I have a 1989 Audi 200 turbo, non quattro. It has 160,000 kms and was stored for 6 years. I bought it this past February and it was great as long as the weather was cold. Now that it's hot out the front...

It has a lot of miles, but runs well--until recently. When I take a corner, it dies. The lights on the dash come on so it seems the whole system isn't shutting down and staying down. If it were a carbed engine, I would be looking to turn up the idle. In all other aspects, it runs well, but this...

I have a 1990 audi 100 that starts and idles fine while sitting. Once I take it out and drive it and it warms up and get it to 3500 rpm's it then backloads and runs poor. It will only go about 15 - 20 mph. It continually fouls out the spark plugs. Have replaced the timing belt and reset cam...

Going crazy here. My Audi 100 will not start after sitting a day or so in damp weather. Cold weather is okay - it seems to be the moisture that's killing me. Weird thing is, the ignition spark is fine, but fuel is not reaching the cylinders. If I put a heat lamp under the hood for an hour or so, it...
