For the over heating problem, assuming that your A4 does not have a low
you should check the condition of the mechanical fan viscous coupling.
With a hot engine and the engine not running if the fan spins easily with
no resistance then the coupling has failed which does not permit the fan to
rotate correctly and pull cooling air through the radiator. For the brake
drag problem, assuming no faults codes, check the rear brake caliper carriers and
sliding pins for seizure-- a very common problem. Audi should have the rear
brake caliper carriers and pins as a regular maintenance item for cleaning and
relubrication at least once a year. But Audis cost so much for dealer service
I doubt that they would consider my suggestion even though I once worked
with their US service engineering manger.
