This car is junky. I owned it less than
a year and had $7000.00+ in repairs.
Most of the time this was my primary
vehicle, I was driving my 1995 Dakota
instead, because it always runs.
The timing belts on these will not last
until the recommended service interval.
This is critical for you to replace
early if you have a 2.8 car. You will be
VERY VERY unhappy if your belt goes.
This will cost you thousands. Just
replace the belt at about 50,000. I
promise you'll be glad you did.
After that disaster, the car still has
not been running well, and as you know
it takes weeks and weeks to get these
repairs done on an a4 at any of the
Either get better water pumps and idlers
or change your recommended service
interval for the timimg belt to a more
realistic 50,000 miles.
