Does this being an Audi recomendation mean you need to get it serviced for the warranty to remain ? http://www.audi.co.uk/audi/partner_...ar_Maintenance_Required/Air_Conditioning.html Just wondering as know how much a/c costs to fix it does go wrong and am concidering getting it done. I suppose it won't have to be done by Audi ? Anyone had it done and is it expensive ? cheers in advance.
