A6 question

[Alexander Lee]

On Friday, a co-worker purchased a '99 A6 Quattro w/ 72 K miles. Friday 
night, the car was coming dangerously close to overheating. The dealer is 
trying for a repair so he doesn't have to abide by 3-day money back 
guarantee, but has yet to figure out the problem.  Any thoughts? There is 
one other thing, the information cluster in the center of the dash does not 
work. Is this a major concern?

Thanks,
