My A3 manual says you must change all four tires at once so they're the
same size. The computer probably doesn't know how to compensate for
much difference in wheel rotation speed.

Hmmm, maybe, but surely when the front wear quicker than the rears,
there would be that slight difference anyway.
My garage is also going along with the weights being the problem now
and is trying to get some of the old ones for me. Tyres have done over
a thousand miles now so definately not down to slipping. Funny thing
is it only does it for about the first few minutes after starting off.
I turn the ASR off then on again and it won't do it again even if I
pull to a complete stop and start off again. It's only when the engine
has been switched off. Perhaps the ECU for the ASR learns to ignore
certain repeated signals?

Are you sure it says *must*?
It probably says something like ideally all 4 tyres should be of
equal tread depth, or at least a maximum tread depth difference
front to rear of 4mm.
It probably also says you should ideally have the same type of
tyre (size, make and tread pattern), between front and rear, and
definitely in identical matched pairs on axles.
The ESP computer should re-calibrate itself, everytime you first
drive off from a cold start, in two stages, the first around
5mph, and the second stage at around 30mph (it could be 30kmh).
This really needs to be done on a straight flat road - could be
difficult if you live on a steep hill, or hairpin bend!
One of the other posters I think mentioned you need to *run-in*
new tyres - on the front - 100-200 miles, on the rear (of a front
wheel drive) 500-600 miles - to remove the releasing agent the
rubber is coated in when the tread is moulded during manufacture.
