Hi, can anyone tell me if the audi dealership is supposed to change the engine mounting bolts (stretch bolts) during a cambelt change. I had the cambelt done by them in June 2009 with a 2 year warranty for the work. My engine mount on the drivers side has gone and i cant see on my receipt any mention of the bolts being done. If they have not replaced them then of course i will be looking to have the work done for free. I know that these bolts are "stretch bolts" and cannot be re-used. Thanks for your support.
