Hi My S3 is coming up for its second AVS service. It's done 35,000 miles and is classified as AVS Major. Audi main dealer has quoted £410 inc VAT. Now, I assume an Audi independent like AMD will charge less, but how much is the Audi dealer Service History worth when it comes to selling the car? Probably more than the saving in going to an independent for the service. What do you guys think?
