Well went to the dealers today and after 30 minutes was told they had underestimated the size of the job, and would need book the car in for a full day! There is also a recall on the MMI & instrument cluster (both require a software updates) So they need the car for a full day. Thankfully they will still honer the original quote, and will give me a loan car for the day. On a positive note, the dealer has told us we can collect Mrs B5 new A3 tomorrow, just hope it's not a lemon like my first A6...
