Hi,

Touareg 7P 2011 Air suspension stopped working and I replaced compressor, valvegroup and relay for compressor. Still have faultcode that won't go away and therefore system doesn't allow any filling etc..
Don't have any ideas were to look next, have gone thru all fuses, relays, car battery...

Any thoughts?

Fault code is :

I am sure that this error is keeping the system from starting. 0599 - Pressure Sensor for Ride-Height

However, I am not able to find any useful info for 0599. Hopefully someone knows what this is.

If you have installed new working parts, then wiring issue or controller issue???

C1031 is the Right Rear Wheel Speed Sensor Circuit.

Level control pressure sensor G291 is a part of the valve block. Did you purchase an OEM valve block, or a knockoff? Check VCDS measuring blocks in 34, search "pressure" to narrow down the blocks. You should be able to see data for each corner, accumulator, and compressor/system pressure. If not, you definitely have an issue with the sensor or wiring. Check the wiring to the sensor, valve block 10 pin connector; pins 5 (5v positive), 7 (ground), and 9 (pressure signal). Check between pins 5 and 7 for 5v with the ignition on.
