I bought an Audi A4 convertible in November and from the day I bought it I ve had problems with the engine and smoking through exhaust. I took it back the next day and they kindly tried to fix the problem by cleaning cylinder head but the problem hasn t gone away and I m now having to pay out hundreds of pounds for a new engine due to the engine failure on this Audi that was apparent to them before I bought it. Raj is pleasant but obviously knew there was a problem as one of his workers informed me when I returned it so I will definitely steer clear of them in future. I ve been driving and buying cars for over 24 years and first time Ive been done over so lesson learned.
