Thanks guys,

I will indeed change the temp sensor.

As far as water pump goes, I am told by my Audi indy that the water pump
on my motor variant (AJL) is *not* driven off of the timing belt, though
it seems to be a universal truth on this forum that all water pumps are.

My timing belt was changed one year ago at 110 000 km and I find myself
sleeping better at night as a result.

. . . I will nonetheless be left with a more weird problem, that the
car is very hard to start about 10-30 mins after shutoff, requiring the
starter motor to spin for ca. 15 sec before the motor starts . . . more
in another thread I will start shortly.

Cheers, Robert

True - your water pump is driven by a small belt taken from the power steering
pump - which is spun by the big ribbed belt...

That was not the point ...

To replace the water pump _or_ the timing belt, 90% of the
job is done - replacing the other one as well. The thumb
rule - is to change both at the same time, to save work hours
