My RS 6’s air con still working inasmuch as it blows fully but not very cool. Any suggestions would be much welcome.

Also my local main dealer wants £500 for an oil change only, nothing else.  Any suggestions would be much welcome.

Also Audi are recalling my car for modifications to the turbochargers oil strainers, of which there are two. The recall letter states that the work will take one day, but the main dealer wants the car for at least three days. Any comments please.

I'd ring round to get quotes from alternative Audi specialists for the oil change quote. 

You'd be best getting a diagnostic check to see if any fault codes flag up with the AC. 

 

Hello Steve 123,

Wouldn’t surprise me if your air con. system just wants some re gassing.- after leak testing. A local air con. specialist or suitably equipped garage should be able to sort that quite cheaply. 
 

Oil change? I seem to recall that your model uses a ‘special spec.’ oil, so as Steve says, worth trying an independent, but have a chat to establish they know what oil it takes. I would avoid any other cheap quote until you have done your homework. 
Kind regards,

Gareth. 
p.s. could you please complete your profile.
