Has Audi programmed in throttle damping to reduce noise on my R8?

I have a new Audi R8 V8 manual and I have noticed a hesitation when accelerating hard from 30mph in third gear. It turns out that this corresponds with the EC ‘drive-by’ noise test, so, to pass this test, it transpired that Audi has programmed in a momentary throttle damping. I have applied an interrogation programme via the OBDII port and discovered that when accelerating hard from 30mph, the actual throttle opening temporarily reduces to just 15 per cent. I think this can make the car dangerous in overtaking manoeuvres and would welcome the opportunity to let you try the car and give an opinion.

I did try the car and you are absolutely correct. The throttle damping is not only shown on the interrogator, it can be felt as a sort of ‘roller coaster’ effect, but only when accelerating hard in third gear from 30mph. I agree, the throttle damping must have been applied to pass the letter of the EC ‘drive-by’ noise test if not the spirit. But it is very momentary and, though irritating, I don’t think it is legally actionable as a ‘fault’.
