I jus recently brought an Audi A6 2.8Q. Im scared of the high maintenance costs. What should I look for to be fixed soon????

 

Welcome to world of Audis. If you're "scared of the high maintenance costs" hopefully you're good with a wrench, DIY, otherwise Audi maintenance can be quite expensive.
High on the list for your year/mileage is the T/B, can be $ 1200-1500 at the dealer, cheaper if you find a good independent mech (indie ). Do you have the service records/ manuals/ books ?
