This is a 1987 Audi 5000 CS, the turbo quattro model, with locking center and rear differentials. This car has a few small modifications done by a previous owner, including a mod that allows slightly higher boost pressure and an aftermarket intercooler. The car is in running and driving condition, and it is pretty fast, but it has some issues. The main problems are that the hydraulic system leaks, so it needs to be replenished from time to time. The power steering and brake assist still work. I don't know where the leak is, but I think it may be pooling up under the driver's footwell, and water may also be entering that area. I've carried out some repairs myself over the years, but I'd like to pass on the responsibility for keeping this cool car alive to somebody else. The AC compressor is disconnected, and the AC doesn't work, but the heater is fine. The car has power windows and power and heated seats. There is a working stereo and CD player with remote. It sounds pretty good. I've had the car since 2006. The odometer stopped working at 260,000 miles, and I have continued to drive it, but I don't have any idea how many more miles I've gone. I'd guess around 20,000 miles. I used to live in an area with a lot of snow, and the car is incredible in the snow. With the differentials locked it's virtually impossible to get stuck. The clear coat is cracked and looks pretty bad in some places, others still look perfect. The seats are ripped, especially the driver's seat, and the front seats came out of a '90 V8 quattro, done by a previous owner. Some of the exterior trim is worn or missing.On Feb-26-17 at 11:09:50 PST, seller added the following information: Question and Answer stuff: When you say you have to top off the hydraulic fluid, do you mean you are topping off the brake/clutch reservoir or the power steering reservoir? Does the car seem like it has ever been in a serious accident? Are any of the interior electrics broken like window switches, light switches, dash switches? Does the horn work? (I'm not expecting a perfect car, I just want to know more or less what i'm getting into) Is the modification to increase boost pressure a manual boost controller? The hydraulic fluid has its own reservoir, and it is used for the power steering, for the brake assist, and I believe for self-leveling suspension. For a long time, the brakes shuddered and were not very effective. I eventually determined that the problem was the the hydraulic pressure accumulator (often called the brake bomb). After replacing that, the problem with the brakes was fixed. But there continues to be a leak somewhere in the hydraulic circuit, perhaps at the steering rack, but I'm not sure. The steering assist is there, but it is not as much assist as one might expect. Also, it seems that the fluid might be pooling up at the driver foot well. Hard to tell what fluid that is. To be clear, this car uses hydraulic pressure rather than engine vacuum for the brake power assist. The boost modification was done by a previous owner. Thinking back ten years to conversations I had with the person that sold me the car, I think he said that a diode had been placed somewhere in the ECU. The result was to decrease the duty cycle on the waste gate solenoid, allowing it to stay closed at higher pressures. Here is a link that might help describe it: www dot sjmautotechnik dot com/trouble_shooting/boost dot html Quoting from the link above: "The ECU is designed to cycle the waste gate solenoid with a varying duty cycle, to allow the waste gate solenoid to add manifold boost pressure on top of the waste gate diaphragm, to assist and hold the waste gate closed and help the waste gate spring pressure." It is not a manual boost controller. The car does not appear to have ever been in a serious accident. The windows and all switches all work, I think. I'll go double check. Horn works. The CV boots are torn and have allowed some greasy mess to be spread around the area. I am running out of characters, so I'll check the switches and report back in a separate message.
