Hello everyone

I got a 2004 A8 D3 4.2 V8 Petrol. The suspension was working fine compressor, different heights etc. I had a front left level sensor fault which would give me a headlight level error. Before a changed the sensor I scanned the car and got these faults:

I changed the sensor and at the same time I was also replacing the front discs and pads. When I finished the left side i started the car to move it and the Amber suspension light on the dash was out and no headlight fault so thought i had fixed it. I then changed the right disc and pads lowered the car and noticed that is was really low at the front, started the car and both amber and green suspension lights where flashing on the dash. I ran a scan and cleared all faults. the only one that came back was the one below:

The when selecting different modes in the MMI nothing happens, car doesn't raise up and cant hear the compressor running.

It is simply a matter of running the Suspension Level Control Calibration on VCDS after changing the level senor?

I think its in Emergency Running Mode from what i've just been reading. Can that be caused by jacking the car up without putting into jacking mode?

Maybe should mention that the outside temp was about 3-5deg C when i did the job and took the car for a spin this morning it was about 1degC with the same result

I have checked the relay, fuse and pump and all are working.

I started the car and ran the pump for 30secs by shorting the 2 pins on the relay but the car wont lift up at the front. I also ran it for 30secs without the engine running but still didn't lift the car.

I cant hear any leaking air. If its not lifting the car up I would think it was a massive leak that i would hear. The rear of the car is sitting just fine.

Is there a way of testing the valve solenoid block? Its not coming up with any faults.
