never mind. found it.

could you post the link? i tried searching, but no luck.

(i found "Some common problems on 2004 Cayenne S," but no pics.)

i no longer have the problem, but am curious to see your post.

Hello.

I had the same problem with "air suspension faulty workshop" alarm everytime i started the car. I have put a description with pictures in the DIY section. Hope this might help you with your problem.

I'll keep my eye out for you. I have a gray CS, and am usually in the Bellevue to Tukwila area, and sometimes my wife drives it to Kent.

Btw, I have had similar experiences, so stopped waving. Anyway, as you said, there aren't many Cayennes around.

I rarely ever see any Peppers on my daily commute. But tonight, coming home heading north on 167 I was being followed by those distinct headlights. There was quite a bit of traffic but I could tell this driver wanted to get past me. Traffic cleared and I merged to the right to see what type of Cayenne was following me. I was expecting the driver to pull up along side of me so we could exchange a pleasant thumbs-up but this guy just did a quick fly-by and left me with my thumb sticking up in the air all by itself It was a gorgeous white (somehow clean in all this recent rain) GTS! Well, kinda peeved about not getting a return wave I manually dropped down to 3rd gear and proceeded to pass the guy with ease. My '05 might only be up 30hp but you can't deny the extra torque in the biturbos. I slowed after showing him my taillights (honestly, I wasn't even sure he was racing) and he swerved out into the HOV lane over the double white lines (illegal to cross and illegal b/c you need a passenger) and took off. And that was that.

The second Pepper I saw was on the 405N just b/f the I90 intersection. He was in the right lane making an exit. Again, it was a new GTS only in the fastest color (black). I waved but, again, no return or even a glance. Oh well, maybe the Cayenne crowd isn't into those types of exchanges. When I had the CTSV people would flag you down to talk cars. Maybe it's an American muscle car thing?

Thanks.

Well, hoping for the best. My guess is I'll probably see it again.

Well a reset may have cleared it but that fault is a strange one. I first had it 2 weeks from new and the compressor did not go till 70K

Good luck

Update.

Two days later, after I had the diagnosis done, I tried to start the Cayenne and the battery went almost dead. And while dying, gave me another error - Steering Faulty. Tried to jump start it but locked up the steering wheel and wouldn't start. The key would move but wouldn't unlock the steering wheel.

Had it towed to the dealership and after putting in a new battery, all errors disappeared, including the Air Susp warning. The tech tried every thing to get the Cayenne to give the warning, but thankfully no warnings.

The interesting thing is that it was a different tech earlier and he said the solenoid blk and compressor needed to be replaced. And now with a different tech, all systems fine. Something just did not sound right the first time.

Anyway, I hope my experience helps someone in the future.

It was just the battery that needed to be replaced.

Got the copy of the service order today.

Fault 1772 in level control for pressure sensor lead. Checked the air suspension for leaks, all wires ok. Diag sheet recommended to replace the solenoid block, but bulletin recommended replacing compressor.

But then a search online for TSBs... "LEVEL ADJUSTMENT FAULT CODE 1772 - PRESSURE SENSOR SIGNAL LINE -- THE DIAGNOSIS FOR LEVEL CONTROL FAULT 1772 DOES NOT INDICATE THE LEVEL CONTROL COMPRESSOR AS POSSIBLE FAULT CAUSE."

Will check with VW dealer tomorrow for the repair kit. But wondering if the compressor is ok and only the solenoid block needs to be replaced!

Any inputs? mudman2? RFM?

Thanks again.

Thanks a lot... I'll check with the VW dealer next.

No special tools are needed. The kit contains: 1 tubing ( not needed for Cayenne - different design ) 1 cylinder/pressure body inclusive temp. sensor and 1 piston compression segment. Ask the V.W. dealer for an overview of the TB with the rebuild instructions, there is just one tricky point to look at, the exact segment possition on the piston. I can explain it but a image is a lot easier. Removing the compressor from the car is a piece of cake.

Thanks to mudman2 and RFM.

I am obviously now interested in the repair kit. I was able to find the part number (7LO 698 030), but nothing more online.

RFM, can you give me a little bit more detail about the repair kit and how it works? How much work is involved and does it require special tools? Thank you in advance.

I started getting the "Air Suspension Faulty Workshop" warning about 3 to 4 weeks ago on my 04 Cayenne S. And just like others here, every time I restarted my Cayenne it would go away, but it also wouldn't come on for a few days. I haven't been able to figure out what kind of situation/action causes it to go off.

After reading a few posts, I decided to take it to the dealership to run the diagnostics. The dealership says I need a new compressor and an air suspension block, and would run me about $1300-1500. But interestingly, also mentioned that it won't hurt the car if left as is, the air suspension just won't work at its 100%, and if left at the same level, it should work just fine. But I get the warning sometimes even if I don't change the level.

Now I am confused about spending that kind of money and getting it fixed if it is going to be fine as long as I don't change the levels too much. :unsure:

Have any of you had a similar problem? And does anyone have more insight into what might happen if I don't get a new compressor and block.

I am ok spending the 1500 if it prevents me from getting a bigger bill later.

Help! :help:
