Graham's actually referring to the issue encountered when pulling gently away from standstill, or, far more pertinently, when attempting to ease the car along in stop-start traffic.
When we met at the APS day, He actually gave me a graphic demonstration of how the basic problem manifests itself. It's simple, try it when you next get into your S5.
1) With the car in neutral and at idle speed, press the throttle very gently, aiming to gradually feed-in the revs. You'll accomplish this no problem, revs rise in a smooth linear fashion as you would expect to be the case all the time.
2) Now, attempt the same with the clutch depressed fully, car still in neutral.
I tried this first in Graham's car, and then in my own. It was astonishing - with the clutch depressed, the same gentle application of the throttle suddenly brings in the aforementioned surge of revs from approx 550 up to 2000 or so - it's impossible to increase engine speed in a smooth and linear manner with clutch depressed.
It seemed that this demonstration was a far starker illustration of why the car is a frustrating handful in stop-start - and that there is clearly an electronics-related issue here - whether it's anti-stall related or not, it's a fault and no amount of driving around it makes Audi less culpable.
Oh, by the way Graham, that's a yes - I'm p*ssed off too!
