Hi guys, since you were all so helpful with my Touareg woes, I am hoping someone may be able to give us a steer on pinpointing the new issue on my A6.

This issue appeared randomly a few weeks ago, started with a couple of warnings like "Vehicle too high, controlling level" which would sort itself out, but since then the latest issue has been that it is stuck in Car Jack mode, on maximum height and stiffness, with a warning to not drive above 35mph. This is also giving an adaptive headlight warning.

When plugged into VCDS - seemed that the only functionality I had was to test the compressor relay (which came on OK), but no control over ventilating the shocks. Feels a bit mad that it won't pinpoint the failure item that is stopping it.

Looking at the measured values I could see that whilst the absolute ride height values wouldnt change when manipulating the level sensors, the sensor PWM% would, and can confirm all sensors moved appropriately.

Here's where I think I messed up - I tried to do the re-calibration of ride height, and got as far as clearing the stored ride height values, but now any further steps in that process won't work on VCDS including Set Reference Level. So now that has given the additional error, but also seems to have dropped the rear right considerably (but not to the floor) so the car is completely unusable now.

Autoscan attached - would really appreciate any advice on what I'm looking at especially in the ABS errors would be appreciated!

The faults in 34-Level Control make me think there's something wonky with one of more of the ride-height sensors. Check measuring Values for height to see if one of the four corners is out-of-whack.

Thanks Uwe. Before I started messing around, there was one that was a few % out compared to the rest, but they all seemed within 5% of each other. Now the car has started to droop, they are all kind of all over the place, which makes sense? They all respond to movement as expected.

Now that I've annoyingly deleted the calibration for level control - all heights in measured values are static, and it's only the Level Sensor PWM% value that moves.

Out of interest, if a failed component is blocking a VCDS function from happening, why doesn't it specify which conditions have not been met?

It's not VCDS that's blocking a function, it's the control module in the car, and it's not all all unusual for that to happen without any fault codes. Yet you have several...

Yeah I know, I'm just thinking how nice it would be if everything was pinpointed specifically for smooth brains like mine :D

How best to identify the "mechanical failure" then, disconnect the level sensors and move them through the range of motion to see which if any aren't playing ball? I have been underneath and none of them are disconnected or damaged.

Sure, you can do that, but personally I would start by having somebody rock each corner of the car up and down while watching the values and only go to what you're suggesting if that doesn't turn up anything obvious.

Given the "mechanical failure" codes and the fact that the car won't air down, I suspect your valve block is at fault here. If you're slow and careful, you can "crack" open the air fittings just enough to let the pressure slowly escape in a controlled manner without actually popping them out of the valve block entirely. Once you've depressurized all (4) wheels and any other pressure vessels (such as auxiliary air tank?), you should be able to remove the valve block.

You can try 1-2 drops (NO MORE!) of air tool oil (NO SUBSTITUTES!) in each opening in the valve block, then re-install to see if that helps free anything up. Some percussive maintenance with a rubber mallet could also help. Ultimately, though, you're probably going to have to replace it.
