| If you have a friend with a vag-com scanning tool it would help a lot...But you can also visually inspect the height suspension sensors. One of them might be dead/beoken. Also try to lock/unlock the suspension a few times and try to hear if the compressor makes any noise. The compressor might be shot... One other thing you can do is measure all four wheel heights(from the very top of tire to the center of fender flare above tire) They should all be the same hight... | |

| How much did you end up paying for the control module manster? I don't know anyone that has a vag-com so I guess I will have to take it in to have it looked at. I can't adjust the suspension at all. It wont let me put it into jack mode or take it out of level 3. Compressor is only about 6 months old, the guys I bough it off of just had it replace around 10000 mi ago? | |

when left at level 3 no leaking or reduction in height driving over 80km/hr will drop continually to bottom/flashing light at 1 and will not come back up unless I stop turn off the car and restart. Even then it comes up with difficulty. An independent Audi repair shop has suggested replacing the airbags. Could the problem also be the control module and or the compressor or all of the above. Cost estimate is about 3000$. Do authorized Audi Dealers have any way of testing to determine exactly what the problem is? What about going to spring suspension as an alternative? Any help would be appreciated. I live in Northern Ontario David

Replying to: shebe (Jul 28, 2009 6:55 am) Could be control module or some level sensor (you have one in each wheel) or maybe just a bad wire connection. One way of testing is raise so you can be under the car (by the wheels on a platform) turn on the car, begin at level 3, and manually set to level two, the car should lower, listen for the compressed air leaving the suspension system, check if it stopped at level two or went all the way, if so check all sensors for lose or cut wires. If nothing evident go to an Audi to check the control module. DONT GO TO SPRINGS, if you plan to do that change cars, for an A4 or A6 Avant.

Replying to: shebe (Jul 28, 2009 6:55 am) I drove my car like that for 3 months and only got worse. To the point where in level 2 you could literally hear the air coming out. But in level 3 it would stay up for months. So I avoided highways and going over 50miles/h. In the winter the hole gets bigger also for some reason... Get an arrnot bag and do it yourself. It's fairly easy. I would help you for a beer

I have a 2001 2.5 TDi Automatic Allroad with an unusual suspension problem. Instead of the usual problem where the bags leak, I had the opposite problem whereby all four bags were stuck on full!. When starting the car the top green light would flash which would indicate that the sensors were still doing their job in telling the car to release pressure in the system, but nothing happened. I even tried driving at 70 MPH on the motorway to see if the speed sensor worked, it did i.e. the top two lights flashed but it was still stuck on the top setting. I suspected that the compressor was at fault, so I had a replacement one shipped from Arnott Industries. After fitting it there was no change to the problem (no power to the compressor and still stuck at full height) I decided to disconnect the air hoses manually at the valve block. Firstly I disconnected the yellow connection to the pressure reservoir which emptied the tank but had no effect on the suspension so with the aid of a colleague disconnected the air line to each of the four air springs to level them out manually. I am now in the position whereby when I switch the ignition on, the warning light on the dash is on constantly (I seem to remember that it used to flash for a while and then become solid) the lowest green light in the centre console is flashing as the system is calling for air. There is no power to the new compressor and after using a friend’s VAG.com it has a fault stating that there is a short on the solenoid which I thought was on the new compressor. After obtaining a wiring diagram for the suspension I understand that there is a main 40AMP fuse and relay supplying the compressor. Having looked through the forum I understand that it could be on the relay panel (driver’s side, behind the micro central electric panel). I have looked at my relay panel but it doesn’t look like the one on the diagram that I found. Does anybody out there know where the main fuse and relay located? Any help or advice would be greatly appreciated. |
