My mate who works for Audi got me a retail price for all the parts needed to do my cambelt change including waterpump, tentioners, pulley's and all relevant caps/seals etc.. (it was a pretty big list). No spark plugs or brake fluid, but all other service parts including gearbox oil and it came to over £800!!! That was full retail so he was going to see what he can get it for. He said if I phone Audi and ask for a quote to replace the cambelt they won't quote for the other associated parts (as this is what Audi tell them to do!). He said that there's a lot of parts to replace on my engine as the rocker covers need removing and various seals/caps must be renewed or I will have oil leaks. He also said that you must use the proper cam lock tool to tension up the belt properly which makes me wonder if an Independent garage would have the right tools?? Has anyone else taken their cars to the main dealer for a cambelt and then been hit with additional costs?
