Okay, so as well as doing the DSG work for £110, Ridgeway VW in Reading have now offered to do the cambelt for £299 - Which is a result, doesn't include the water pump, so just waiting to hear back on a price for that, but otherwise, very very pleased with that. My original quote (from Windrush VW in Maidenhead) was £725 and I've now managed to get this down to £409... Not bad at all!
