As title suggests, do people let their tubby cool down before turning the car off? how long do you usually give it?
They have a coolant after run motor that is supposed to help with this (if its working) s3s do anyway, not sure on an A3
.I just don`t nail it all the way home, cruise the last mile or 2 under 3000 rpm.

As S3Dave mentions, they have an auxillary coolant pump that cools the turbo down after the engine is switched off. It performs exactly the same function as sitting and idling for a few minutes does, but saves you petrol and wasting time, there is no benefit in doing the latter or fitting turbo timers.
do yourself an experiment.. Best done at dusk..
its quite a spectacle!
Yes it is..is that an xs power manifold that welly has in the second video??

find your local hill, and belt up it.. get to the top and stop (leave engine on!) and open bonnet and see the glow... and see how long it takes to go away.
? does the turbo have water cooling ? if not how will the coolant pump help ,
walking down the turbo for the last few miles is always a good idea , switching off after a hammering could be a problem because the oil circulation stops, oil cools the bearings and as the turbo is very hot it can burn off the standing oil left in the turbo allowing the turbo to spin down with dry bearings the turbo will spin for a while after the engine is switched off

didnt know these turbo's were water cooled you learn something new every day , dave's baking oil is a better way of what i was trying to say above
all in all we agree a cool down is a good idea to extend turbo life

Just ensure it works, you'll hear it running like a quiet fan noise without the engine on.
Unfortunately they just stop working, you can try tapping them but ultimately its a new pump, luckily you are not tied to audi for this as the pump was made for many manufactures inc Vauxhall (omegas) about £40 on ebayHmmm....
I'm sure mine did this when i first got the car but cant say I've heard it in a while
Is there a fuse or something i should have a look at?

ibiza's have em too...
clearly all the classy cars have them
I'm sure the 180bhp leon cupra doesn't have the after-run pump either? I don't think I've ever heard it on Bobs leon!
Apparently thats right, aren't they the 180bhp engines also fitted to the A3? It's bizzare in that case that they decided to fit the pump to a SEAT and then not to the A3 with the same engine.
no ibiza's mainly came with little k03 and 156bhp as std in mk3 form. they did do the limited ibiza cupra-r which was 180bhp, with brembos but they also were k03 with factory remap essentially.
It didn't, because it doesn't have one!
You'll be lucky finding it to tap, because it doesn't exist!
Only S3's / LCR's and such like have the after-run pump, A3's do not get such a device.
