Help with Q7 air suspension fault

[Mungo2007]

Hi 

I need some help with a suspension fault on a 2007 Q7 i have the dreaded orange warning light on the dash, VCDS says electrical fault, the car runs fine suspension is at the correct heights and the adjustment on the MMI all works. 

Has anyone got any ideas on where i can start looking for the fault?

Thanks

Hello Duncan, 

Has the car been standing for a while and not regularly used of late? 

If so, it is not unknown for low battery efficiency to throw up lights/codes. 

If not battery associated, and ride heights are OK, weak point can be the compressor (well actually the compressor piston ring). Known contact for replacement ring if that is the issue. 

Kind regards,

Gareth.

Hi Gareth 

Car has been used everyday so i don't think the battery is a problem but i will test this anyway. 

Ok so the compressor is the first area to look at are there any ways of testing the compressor to see if this is the fault?

Sounds like a diagnostics next move Duncan. 

Maybe something completely different, so worth getting that done before jumping into anything. 

Kind regards,

Gareth.
