2002 Allroad Suspension not working

[karmann]

Help needed my suspension has stopped working.
Was working fine then nothing.
Ride height adjustment light is on all the time.
ESP button does not turn the light on and off
When the ride height adjustment button are pressed it still stays in level 1

Suspect fuse or relay ??

Where are they and what number is the relay please.

Any help would be great

Can you hear the suspension pump running?

You need to do a fault code check and work from there.

Looks like the Level Control ECU has died.

[karmann]

Do you know where it is located and cost to replace please

[allan_audi]

Not sure where it is or how much.

Did you try and clear the fault code, if that doesn't work try disonnecting the battery and reconnecting. Don't forget your radio code will need re-enetering.

[karmann]

cheers i will give it a go
