Hi I’ve got a rs4 suspension warning light keeps coming on, had it at Audi paid £900 to fix but day later still fault on dash. Any ideas cos can’t look at it Agian for a month, attaching invoice of job 😬

Hello Chris,

Thanks for joining, and sorry to hear of your continued plight. 
As I see it:- 

You paid Audi to successfully repair your car - they haven’t. 

It is no good speculating what maybe the cause of the continued issue, and even if someone does suggest possible causes, then you cannot get anyone else to fiddle with a vehicle that’s just come out of Audi’s care, otherwise they will understandably wash their hands of it. 
Your only route forward is to put pressure on them to re-inspect the car as soon as possible, and not in a month’s time. Speak nicely with the service manager ( rather than a service assistant) and see what you can agree. 
Perhaps you can let us know.

Kind regards,

Gareth.
