End-------------------------(Elapsed Time: 03:50)--------------------------
Step 4 Describe recent repairs or services, problem at hand, & attempts at repair.
No recent repairs or services. No attempts at repair. Problem is a flashing yellow air suspension light, and the rear end of the vehicle is jacked up to maximum height. Any attempt to use the button in the trunk area to lower the rear has no effect other than causing the light on the button to flash.

Step 5 Are parts OEM or AFT? If so, "what", and what origin?
Original/OEM.

Step 6 Identify specific issues to be addressed/concerned about, or say ALL.
I'm only concerned with the Air suspension codes. Not concerned with anything else unless you think it's directly related. I have routinely seen all of the other codes. I haven't cleared it in a LONG time, but I have cleared them in the past and they come back (CAN, door central locking buttons, glo-plugs, distance sensor heater, etc - nothing that either really causes a problem or is worth the cost of fixing).

Step 7 Now that you jumped through the first few hoops of fire, did you check the FUSES/Battery connections?
No. I have not checked any fuses yet. There's no indication that the system is not getting power. It seems to be running for too long and getting cut off.

So, now that all of that is out of the way... It seems I have a LOT of information to point us to the problem, I just don't know how to interpret it all. We have four fault codes, the flashing yellow light (which indicates that the rear suspension is at maximum level), a visual check which confirms that the rear end of the vehicle is jacked up unusually high, and confirmation that I cannot lower the rear of the vehicle using the button in the rear cargo area. No unusual noises or behavior, though with the rear end up like that, it is noticeably impacting handling. This is my main day-to-day family vehicle so I need to get this fixed quickly! I have owned this vehicle for almost two years. It has had intermittent air suspension problems the entire time, but never anything like this. In the past, the problem always went like this: After a startup, the system would drop the suspension all the way down and the green air suspension light (pointing down) would stay on. All air suspension options in MMI would turn gray. I would stop the vehicle, turn it off, restart it, and the problem would go away and not return for weeks or months. The problem I have now is totally new, where the rear end goes all the way up and the yellow light flashes.

Is there any additional data I can collect? I read something about collecting some measuring blocks, but I didn't see any details on it.

Thanks in advance all! I will update this thread to its completion.
John

Another data point I've noticed, now that I've parked on flat surfaces a few times - the upper right of the vehicle is definitely higher than the rest of the vehicle, by about a full inch.

Getting closer to the root cause...

I found the info on measuring blocks. The height measuring blocks confirm what I'm seeing on the vehicle, so all of the height sensors seem to be good. At least that seems to rule out any problem with the height sensors.

I also confirmed that the computer attempts to operate the rear valves by viewing the measuring block 7 in Group 34. Here are two excerpts that show the computer operating the valves open and shut. The left rear lowers as I would expect it to do when the rear air valve is ON.
Code:
20:09:56 Group 007:  Status of pneumatic spring valves
  OFF   air spring valve  front left
  OFF   air spring valve  front right
  OFF   air spring valve  rear left
  OFF   air spring valve  rear right
--------------------------------------------------------------------------------
                Address 34: Level Control  (4L0 910 553 H)

20:10:25 Group 007:  Status of pneumatic spring valves
  OFF   air spring valve  front left
  OFF   air spring valve  front right
  ON   air spring valve  rear left
  ON   air spring valve  rear right
I also tried numerous things today to rule out other possibilities. I confirmed that the 40amp fuse to the compressor is fine, and I was able to
raise the vehicle all the way to the top in the LIFT position. I confirmed that all four wheel arches were raised to virtually the exact same height (although the height measuring blocks weren't exactly equal, but at least at the uppermost position shown in the display, the height was exactly where it should be for all four). I could not hear any leaking at all when this occurred. Also, one of the times I was monitoring measuring block 6, I could see 9.11 bar, which seems like pretty high pressure to me. So, this seems to rule out any problem with either the compressor or the ability of the air struts to hold air.


The next questions are:
1) Why won't the right rear valve actually open? Could it just be stuck, or possibly a failure of an individual solenoid or relay somewhere?
2) Where is the valve that controls the release of air from the right rear? Is it one valve, or are there multiple valves involved? Is it in a central valve block such as the one shown here:

It worked!!! With several taps of a hammer on two long socket extensions to reach up to the valve where the air line enters the top of the air shock, the valve must have loosened up inside and the rear end now completely lowers using the switch at the back of the vehicle. This sounds like a joke, but I really did resolve the problem with a hammer.

I'm guessing there is some internal corrosion on that valve that caused it to get stuck in the first place, and that I'll need to replace that valve. Looks like a frustrating job - there's very little access into that area.

Did you boil it out on kitchen stove with distilled water and then run 90% alcohol afterwards and dry then lube proper ?

Thank you for self helping yourself with JPPSG and making good use of guides to address your issue.

Hi, these valves happens to fail once a while, there is a rep kit for it, not that expensive either. See VAG SelStudyProgram 362 Q7 Running gear pg 33, for position and description. The see hyperlink for explanation of part, I got a valve for my A6 Allroad from another place (can not remember where), but this can give you an idea what to look for. Look at bottom of page, or 2nd page. http://www.air-suspension-shop.com/Repair-Kit_9

On the Audi A6 Allroad, the procedure is to remove the old valve, this will cause damage to valve (and it differently needs to be replaced), not sure if it is exactly the same on the Q7. On the A6 Allroad a special locking ring is behind the valve, and the design of this locking "device" is what cause a damage to the removed valve. So if similar, ensure you have the correct valve and understanding of job, prior to remove anything.

Hope this helps, so you do not have to drive around with a hammer :-)
