Audi allroad Suspension Questions



  • dlaustindlaustin Posts: 23

    In case you have not read my previous filings:

    You have a leak in your front air spring(s). I doubt that there is any problem with your air pump. Use the soapy water test I outlined previously to confirm the problem. It is a very simple test and doesn't take much time.

    A very good source for the air springs is

    Even with the air spring changeout, I have decided to drive around town and overnight park in level 3 because I am convinced there is less stress on the air springs at this level. I'm confident the air springs will last a lot longer doing this.

    Hard to believe your allroad has 117,000 miles and this is the first front air spring change. If so, you are a very lucky man indeed.
  • What it means is don't drive over 48 MPH. Order two shocks, two install kits, get the star tool that fits the parts kit head bolts, and find a friend with an air wrench, jack and stands. It took us 5 hours to do one, and 90 minutes to do the second.. if you remove the air line on the bag once you have it on stands the suspension arms are under much less tension and easier to work with. Mine went at 105k and I think i was lucky to go that long.
  • I have an 01 Allroad with 82,000 miles on it. I have had both front air bags replaced in the last few months as well as three of the suspension control arms. The front passenger side of the car sits about an inch lower then the left when left in the second (normal driving) position, as well as the car will lower it self down to the (low) postion periodically when left for a while. Is either of these a concern?
  • I just totaled my 2002 Allroad 2.7 with 55,000 miles. No suspension problems (thank you Lord!). I am considering a 2004 Allroad 4.2. I had one dealer mention that the 4.2 has a reputation for suspention problems due to it's extra weight. Does anyone know of this reputation? I loved my 2.7 so I have no problem getting another one. I just thought the extra 50HP would kinda be cool.

    I have a 2002 Audi Allroad with 55,000 miles. The Air Bag Suspension will not raise the car any more. It started happening on and off, and now the car stays below level 1 all the time. What can I do short of taking the car in to the dealer?

    I saw this blog when I was searching for answers to my air suspension issues. Did anyone figure out the root cause of the problem with leveling? I have also replaced the driver's side air bladder for $1000, but I still have intermittent problems re leveling esp during colder temps. Any feedback would be helpful. Thank You.
  • Wow! Lots of air bag (my dealer calls them "air springs") problems. I read on another forum that you should clean the dirt and stuff off the outside of the air springs once or twice a year, as long-term rubbing of creases with sediment of any type can wear holes.

    I replaced my LF AS under warranty a year and a half ago and the RF just went out (I had to pay this time). Had I known about this AS cleaning, they may have lasted longer.

    I have a 2001, and it's coming up on 100K (I bought it used five years ago with 60K on it). I'm selling it because, after the 90K servicing and this latest AS (they also had to replace my tie rod ends which brought it up to approx. $1200), I can't afford the constant parts-replacing I've been doing, esp. now that I'm out of warranty. I LOVE the car... when it works. :sick:

    I believe I have the answer to most people problem with air suspension but will have to test my theory out on a bad air bag. I believe the problem lies in the air release valve. On my car it will work sometimes and at other times will leak past the valve. I need to take a bad one apart and troubleshoot further. If it were a blown bag it would leak all the time not once in a while. If anyone has replaced there air shocks and would like to donate them to me for experimenting email me at so I can arrange to have them shipped. Thanks John
  • I think you are wasting your time. Both of mine leaked in levels 1 or 2, but not 3 or 4. How do I know this? I used soapy water on the boots and set my car at each level and watched the resulting soap bubbles. Bubbles appear instantly at levels 1 and 2, but no bubbles on 3 and 4. The bubbles appear where the boots are folded over. When the boots are more or less straight, no bubbles. Also, the air leaded out overnight when parked at levels 1 and 2, but not 3 or 4. Obviously, as the leak gets worse, the leaking will worsen until leaking occurs at all levels. I addressed this much, much earlier in the thread.

    Well I broke down and ordered a front air spring cost $620 with install kit. I received it and found that there is no release valve at the top like I was told. After careful study of how this air spring works, I have come to the conclusion that my intermittent air leak is coming from a $2 seal at the top of this shock and not a valve problem since there is no valve on the shock. It makes sense now that I can see how the seal relates to the shock. It would leak more often when it was cold because the seal would shrink. What really bothers me is that no one has figured this out by now there must be thousands of these failures over the last 7 years and yet when I goggled the problem I found no mention of replacing the $2 seal before replacing a $600 air spring. So to everyone with a simular problem try the seal first before you spend $600 plus labor per corner. Also I would recommend raising the car to highest level once a month and spraying water to clean out any sand or dirt from around the base of the air spring. It seems if sand or grit gets between the rubber and the steal shaft it will wear a hole into the air bags. I think the life expectance of the air shock is around 10 years if kept clean in this manner but the seal will fail around 5-6years first. :D

    I am now ordering 3 more sets of seals to replace all four corners. I will let you guys know if it is sucessful in two weeks.
  • Glad I I'll still get alerts from this site. A $2 seal is a lot better than springing $600 bucks. I love my 05, and was painfully considering getting rid of it this month. After reading your message, I decided not too! Thanks for the tip on cleaning too. Maybe we need to make our dealer aware of these tips, so those of us who don't/can't do it ourselves, don't get gouged at repair time. I am.
  • I wish the problem were the $2.00 seals, but I am confident your Audi is no different from the other Audis and your bladders leak, as I mentioned in previous posts. If you use the soapy water method I outlined previously, you would see exactly where the leaks appear and at what level setting. I am very confident your seals do not leak and never will, if installed properly. Replace your bladders!

    Hi, can anyone give me some advice? the problems started when the battery went flat for no apparent reason. The AA were called jacked the car up (not in jack mode) and then decided to tow it to garage. New battery installed. Some days later i heard a squeaking noise drivers side wheel and then a few days later the suspension warning light came on and stayed on. The noise got worse and eventually was so loud it sounded as if my exhaust was dragging along the floor! Took it to garage and they replaced the drivers side rear lower arm and lubricated the suspension lift pump. Next morning warning light back on and suspension not working just staying on level 1, this got worse and eventually I felt as if the car was below level 1, but don't know if this is possible. Read manual and the info on this website and put the car into 'jack' mode and then back out and this seemed to improve height of car back to level 1 (suspension levels still not working), but warning light still on and the squeaking sound came back?! Pumped up all tyres which were all very low and driving back fromt he garage the indicators stopped working. Are these all individul problems or does anyone think it could all stem from the flat battery. The car is now back in the garage and they are trying to source re-conditioned suspension kits for me. Would really appreciate any feedback. Thankyou

    I have a 2001 Allroad that had the suspension pump that continued to run, become quite loud and then it failed to keep the car at level one. This all started while under warranty but it finally failed outside of warranty and we all know that Audi denied any coverage but they offered to do the work for $1500 for a new pump and installation. I am quite handy and looked into this pump and any type of replacement parts and I found a way to replace the pump for about $350 new if you have a bit of time and are a little handy. The pumps are not made by Audi, nor Continental as the label on the pump states. They are made by a company that makes the same pumps for Range Rover, BMW, Audi and Mercedes as well as others. The pumps are the same except for the exterior mounting plates and air hookups and wire plugs. These are minor. You can find the pump for a Mercedes for $300 on eBay or approx $425 in the internet. The mounting plates on either end of the pump are swapped out in about 30min (2 strange screws on one end, drilling out 4 small rivets on the other and replacing with 4 small screw/washer/nuts). The air hose inlet/overflow and output may be different depending on the model but metric nylon quick connect fittings are available at McMaster for about $3-$8 depending on how many you need. You also may need to swap out the Audi Wire plug connector, wire crimps and heat shrink tubing. I found out a good deal about these pumps and their specs. The pumps are all similar except for their brackets and connectors to your vechile. Oh, you also have to screw in your temp sensor to the new pump and plug it in. I spent a week learning about these pumps and taking it apart. I would be happy to answer any questions you may have.
  • Interesting. I felt like maybe these pumps could be replaced a little less costly than the dealer! Thanks for the post. So, I have an 02' allroad with a noisy compressor. Can you tell me a little more about the type of pump you bought? Size? And I am curious to know how it is working out for you too... Thanks
