TVA "With the consequences of a suspension blow out being life threatening, I'd hope everyone starts checking thiers on a regular basis"

Still not clear if the connection failure that "Dude suffered (snapping off) and the bubbling air leakage that I experienced were the cause of "Geek's blowout.

Also, my MFI warned of a STOP FAULT RUNNING GEAR in red...plenty of time for me to schedule a service appointment...the vehicle was behaving fine...no one else has commented that they were given any advance notice of an issue. My MFI came on intermittently over the course of a week.

Another poster Mitchell78 had a thread under STOP FAULT RUNNING GEAR. He had three compressors replaced with no resolution and finally packed it in and bought a passat (!).

I dunno...would still like to see if a failed connector was the cause of 'Geeks blowout, just saying these might be symptoms of related, but different cause.

Your point is right on...check your fittings! (Went looking for the rears...they are behind the plastic liner...wonder what those look like?)

I wonder if they fair better being protected by the liner?,I don't have air,but I would look if I did.
Some good points you made here, and mentioned elsewhere by you, but I forgot to touch up on. Just to confirm, my MFI never gave an indication of things to come. It just decided to break/snap off on the VW dealers lift, while they were taking off the front bumper to do the headlight service up front. One thing was for sure, the drivers unbroken side, was oxidized and on its last legs, hence my deciding to PROACTIVELY replace it out of my own pocket. It's shame that I had to, as I feel right now, especially in retrospect, that VW pick up the tab on this safety related issue. One thing is for sure, I've saved my receipt and saving it in a safe place ;) , in case there ever is a recall. This was no $10 or $100 repair...

I too in the last few days have now been thinking about the rears. I have NO IDEA what is going on back there, as I have never had the chance to look in this damned cold outside. Curious myself if it's a different design back there or not.

Here is my thread on it http://www.clubtouareg.com/forums/f...s/f43/air-shock-air-suspension-might-need-replacing-need-your-advice-33373.html

and here is a far more serious incident, regarding the same repair. http://www.clubtouareg.com/forums/f62/my-front-air-suspension-blew-out-at-65mph-33585.html

Please report the problem on the link provided below. If we get enough of these in, way might be able to get a recall going. After reading the second thread from rochestergeek, this to me has life threatening implications.

I have some good news to report! Just to reiterate the importance of reporting these type of failures with your respective countries transport departments! Transport Canada called me up today, albeit during a very bad time during the day, which was very unfortunate for me and our cause. The inspector wanted to speak to me "in depth" about the nature of this defect, so we weren't talking about no 2 minute type of call here. He gave me his cell number so that I could call him back tomorrow, when I'd have free time to discuss this openly with him. He really sounded intent to see what was going on.

.....A green light of sorts today. Today, I called the Transport Canada guy up, and not 3 minutes into our conversation, he requested that he come and see my Touareg in person, and inspect the overall design of the air suspension, and particularly the parts that failed. I think that this is good news. He wants me to save any pictures that I may have, and emphasized the importance of those! So to any here who have had failures, PLEASE take "before" pictures of the afflicted parts. This will help our case down the line.

I made our "rendez vous" at my place for 10:00 AM this coming Monday, February 8th. If any of you can think of any additional information, wise words, phrasing that I can use when he arrives here, please feel free to tell me now! He mentioned that in the meantime, he will be checking the USA databases to see what has popped up in there, and see what similarities if any there are. Basically the investigation has officially begun! :)

Thanks



 
Even though rochestergeek is south of the border, his story about failure at highway speeds is one that should make anyone take notice...

I mentioned this to him, and also the other case in England. So if Rochestergeek has filed his complaint already, our Transport Canada agent should see his file in there, and obviously help kick start the cause nicely. The T.C investigator already understood my claim of "what if" this had happened to me "on the road at speed." This is what concerns him. So what he is literally doing now, and I'm trying to quote him is, to start researching the technical design of the VW Air Suspension, and by the time he arrives here and inspects the areas in question, he will know how to proceed as what needs to be done. He made it quite clear that they are concerned because we are dealing with a 2005(my case) and NOT a 1995!!



 
This is all fantastic news!

I filed one on friday for the us. I found the porsche air suspension blow out right before I posted mine. His took the bags out in addition to dropping and he rolled his. Oh and it wasnt covered under warranty by porsche......
Rochestergeek, have they called you back or anything?
Transport Canada has, they will be coming to my place early next week to inspect the Touareg, the repair, the "before" pictures that I had taken, etc. This is good news as it's an official start. The T.C inspector will review your case and any others south of the border, for the obvious reasons.

I REALLY WISH you had taken pictures of yours before any repairs.. #-o He mentioned the importance of those..

Not to jinx myself here, but I somewhat wish your actual case rochestergeek was mine. To re-summarize, mine happened while it was at standstill, so I'm using your case to sling shot mine. Thankfully, the inspector/agent is concerned enough about the "what if" hypothesis I presented to him. In the meantime, he is studying and researching the technicalities of the VW air suspension, and if there is anything truly missing in the overall equation when such a failure occurs. They are also concerned that this has happend to a 2004-2005, and not a 1995! Hopefully by next week, when he inspects my Touareg, and everything else like pictures, invoices, etc, we (actually THEY)will have a case to pursue.



 
Good to see the attention needed. After talking with Rochestergeek it became pretty clear how dangerous things could get. He had his hands full keeping it upright. If it means that owners of air suspension Touaregs are given the chance to bring there's in for an inspection by a dealer that'll be far less that the risk of the liability later on. That, at least, would be step one.
FWIW, in the work I do, if we have an air powered device we want to protect from completely dropping we'll install a valve right on the device that needs system air pressure to open. If a line blows, fitting breaks or a pump goes bam the valve slams shut and keeps air in. Called a pilot pressure actuated valve.

I have been thinking and pondering on exactly what you just wrote for the last 2 weeks now. I can't understand why our Eggs don't come such equipped? I have a funny feeling that once the transport inspectors officially realize that in their research, it will be the actual turning point to start a serious case against VW/Porsche. It just doesn't make sense...Is it just me, or something doesn't add up here?

TV, how difficult would it be to retrofit such a valve on a Treg's strut? I'm thinking, if you go off-road and lose an air pipe for whatever reason, you could en up with a slammed Treg in the bush which could cause major damage during recovery or on your way out. Wouldn't it be worth it to "take out the insurance" and retrofit such a system anyway, regardless of the condition of the fittings?
 
This issue happened to bravocharlie from New Hampshire who is on VW Vortex. He had a leak in the fitting rather than a full broken fitting. But he took it in to the dealer and they snapped it off trying to remove it.

The mechanic then used an EZ-OUT to remove it, plugged the hole and proceeded to clean around the area. Then replaced the fitting and sprayed the entire area with a wax protection coating.

Below are the photos of the job as bravocharlie sent me. You can see there is a lot of thread surface for the fitting to connect. So there should be NO REASON for the dealer to have to replace the entire strut. In my opinion a dealer doing that is only building his profit margin.


EDIT: I would suggest for those of you who are in areas where salt is used on the roads you clean around these fittings and use some protective spray such as this: http://www.international-auto.com/wurth-protective-wax-spray2.cfm

While I'm interested in the issue and the investigation, I'm a little less enthusiastic about yet more government intervention in private industry. If the DOT wants to analyze every spec on GM or Chrysler cars, that's fine -- the U.S. government owns those manufacturers now. I'm just surprised some of you are so happy about Transport Canada thinking they even have the ability to "analyze" the engineering behind some of these systems.

To quote a good friend of mine, "If the answer is government, it was a stupid question."

Cheers, John
 
Stainless steel check valve|Pilot operated check valve|Miniature check valve - Single lock valves

Here's and example of a valve that checks (holds) pressure when the supply pressure is lost. The are no doubt other manufacturers out there but they all work under the same method. In the cutaway, the port at 3 o'clock would couple directly with the shock head. The port at 6 o'clock would be the air supply from the system. The port at 9 o'clock is the pilot pressure. That would tee into the supply line so if all pressure is lost the plunger valve shut and seals air in the shock. It would take some investigation for the right size and there'll be some packaging that'll have to be worked out to be sure it doesn't get in the way somewhere.
