#405 of 413 Solenoid release Valve Vag Code 01397 by amb_123 Sep 29, 2009 (5:45 am)
This is what I know there is a compressor on the underside of the car at the rear this charges a receiver with compressed air, this is situated in the boot below the CD changer. Next to the compressor is a block of solenoids each has a different colour nylon pipe connected to it and these are connected to the airbags. The height of the car can be adjusted manually by pressing and holding either the up or down arrow key. The orange light indicates you are in manual if you now press either the up or down arrow again the level will change accordingly. At this point The (ECU) Electronic control unit (found in the boot just forward of the CD) will electrically energise the solenoids to either allow more air into the air bags or bleed air from the air bags. Once the level is reached all the solenoids will close locking the air into the air bags. To test if the pump is Ok you could raise the car up and down at at some point the compressor will kick in as the air pressure drops you can hear it if you listen underneath the car. It takes only minutes to re-charge the system. If the car is only down on one side and the airbag is okay it could be the solenoid or possibly the level sender on the suspension strut. Hope this Helps Regards Andrew Replies to this message: allroadgal (Sep 29, 2009 9:39 pm)

Replying to: allroadgal (Sep 28, 2009 3:48 pm) oh yes, I got the same thing... Well lets break it down; if you are sagging on one air bag- Remove the whole shock or strut Fill a bucket with water place shock or strut in bucket use an air compressor with a "stream sprayer" WITH a rubber tip and fill the big so there is pressure to check for leaks.   if you find no leaks then its time to replace the compressor/distributing solenoid valve. I found it pointless to just replace one or the other because they will both fail around the same point (poor design in the contactor on solenoid). you can get a referb. compressor for 395 from Arrnot and the distributing manifold can be bought from a local Audi dealer for 495 or 520. The ride height sensor has its own code that it will screw with your head lights so you would know very fast it that died on you ($174 each) Replies to this message: allroadgal (Sep 29, 2009 9:42 pm) fueledpassion (Oct 05, 2009 9:44 am)

Replying to: amb_123 (Sep 29, 2009 5:45 am) THANK YOU SO MUCH ANDREW!! I appreciate your help immensely. i guess i can't just replace the compressor, i think it's time to trade the audi in. just replaced boots and tire rods in april and the brakes (esp unit) in November. i just can't afford it, my mechanic only works on imports and says the allroads are the most expensive to work on. it was a great ride.

Replying to: fueledpassion (Sep 29, 2009 7:28 am) THANK YOU! you answered my question before i could ask it, i guess i have to replace both, is audi the only place to get a manifold? Replies to this message: fueledpassion (Oct 05, 2009 9:44 am)

Replying to: amb_123 (May 27, 2009 2:50 am) Hello,   I replaced my front springs with Arnotts last winter. After being quoted $2k for both sides I was thrilled to discover an aftermarket DYI solution.   Other than problems disconnecting my suspension ... and not having the right tools, the springs were easy to install. I think we got the second side installed in about 45 minutes, after figuring things out on the first side.   So far they have worked perfectly.

Replying to: allroadgal (Sep 29, 2009 9:42 pm) Sorry for the very late reply. Yes so far i can only find them at Audi.
#411 of 413 Re: Air Suspension - Arnott [TBeaulieu] by claymation Oct 08, 2009 (4:38 am)
Replying to: TBeaulieu (Oct 05, 2009 8:37 am) Ditto, however, when I took my OEM airbags off the front I found that the top bolts that secure the cover plate to the assembly were very loose. This top plate puts pressure on the big O-ring that seals the unit. I went ahead and installed the Arnott bags, but I'll bet a nickel that if I had lubed the original O-rings and re-torqued the bolts, the OEM bags would have lasted me a few more years...   As above, my Arnott air bags have been perfect. If you decided to take off the OEM ones, be advised there is a press fit fastener that holds the assembly in place that you have to remove. It's a bugger to remove and was not mentioned in the Arnott instructions.
#412 of 413 Audi Allroad - Big Repair Problems - BEWARE by rdchris Oct 08, 2009 (10:43 am)
I've owned my 2004 Audi Allroad since it was new. I now have 46,000 miles on it and over the last 9 months have had to sink $4,900 into it for front air shocks and a new Torque Converter. I stomached the air shock issue, but had trouble choking down a $3,000 Torque Converter. I decided to contact Audi of America since my car has such low mileage. I was disappointed to hear back that the only thing they'd be willing to do is provide me with a 10% discount. After reading many forums I know now that Audi is well aware of the Torque Converter issue and has even changed the seals to a higher quality. Bottom line, if you're considering buying an Audi, don't expect the company to stand behind their product and do expect to be faced with sky high repair costs. Never again!

Replying to: priestess (May 25, 2009 6:08 am) I've owned a 2004 Allroad since it was new. In the last 9 months I've had both of the common problems to the tune of $4,600 worth of repair. The front air bag suspension went bad and recently my Torque Converter went out....all after only 46,000 miles. Go figure....Audi of America turned a blind eye. The car is expensive to own and the company doesn't stand behind it.........Never again.
