Audi A6 Allroad C6 4F Air Suspension calibration problem!!!

[sers77]

Got a A6 with leaks on both rear (suspension), changed them on a 2-pillar lift.

But I left with the car on the lift and when I came back the owner had lowered it, but not all the way down...
Then he starts the car, take it out of JACK-MODE and removed the arms from the lift.

The car is now very high on one side and very low on the other, so no way to start calibration (as the sensors are outside their limits?).

I removed a hose from the valve-block to get it lower on the "high-side", got into calibration, measured, finished and no difference.
Tried calibrating with measured values (some got invalid value, so I adjusted to get them valid), but no difference.

If I remember correctly it´s LF 422mm, RF 362mm, LR 407mm and RR 360mm.

After calibration all faulcodes goes away and the car is happy, but not straight...

Anyone have the recipe to make it straight?

Did you enter the actual measured values when you calibrated it?

Verify the sensor arms are set correctly, often people bump them or fail to verify they are operating correctly during range or final basic settings.

Yes, tried almost any values and nothing helped... The sensor arms look ok and shows all values in vcds, but they are way off... I'm trying to replicate the lift "incident" with empty suspension and car on it's belly...

Now the car is to low for calibration..

 

[Jack@European_Parts]

Often the sensors look like they are fine but are stripped or moved on the actual spline position giving a false reading.

This is why I mark them with a paint timing mark before I start work as a routine procedure.

So, the car went to Audi for some secret calibration, but they couldn`t solve it...
Now I have the car again and I am going to check the Cables to/from the module and the valves (and everything else included in this system).

Does anybody have the pinout for the module (4F0 907 553 A)?

Either I or Audi could find any problems with the sensors...

Changed the valve block and now it has arised from the ground, equally on all fours...
