I've got a '99 A6 that's not getting any heat.  I had the heater core
flushed
last year that helped some but only for a short period of time but before
the
winter was over I was getting no heat again.  The shop said I needed a new
heater core.  Forgot all about it then as from March to November unless it's
raining I'm on my bike not in the car.  Just took the car to a different
shop
and they say the core is not blocked.  They say water pump is not pumping
enough to meet the needs of the engine cooling system and still push
coolant through the heater core unless the motor is turning at least 2,000
to
2,500 rpm, which it almost never does in local driving.  With the motor at
proper temps, reving it in idle to 2,500 rpm did get hot air out of the
heater
vents.  The water pump had been replaced 35,000 miles ago when the
timing belt was changed.  Does this make sense, that the water pump is the
cause of the lack of heat?
