Hi, I've just bought a used A3 with DSG. It has full service history, it says the cambelt was last changed at 60k - it's now at 108k. I've booked it in to get done on Wednesday, there's nothing in the service book that mentions the DSG service. Should I assume this hasn't been done also? What parts do I need to do that? Also the temp gauge likes to fluctuate between 70 and 90, I've read online that this could be considered normal but it doesn't seem right. Last question is I have the Concert single DIN stereo with no CD changer, what is the best way to make this functional with an iPod? Thanks
