Audi Q7 pcode 01767
 

New to the forum and would appreciate the help with this problem have an Audi Q7. Had tyres replaced and drove for 2 days no issue but now air suspension keeps playing up on the front end, mainly slammed to the floor all round but sometimes stays up so presumably not a leak?
The pcode I am getting is 01767 sensor for vehicle levelling left-voltage supply not much I can find on the net for this.
Thanks
