Specifically what Pirelli’s was it? I presume it was just a specific model of tyre at that time?
If it was specific to the Pirelli’s could you not have just fitted a different tyre?
For peace of mind it seems a simple “solution” if geometry is spot on and it’s just those tyres…
Last thing you’d want to be worrying about in that situation eh, totally get that
No idea why it happened mate and yes I personally just fitted Michelins. When it became apparent it wasn't happening with the Michelins I just forgot about it and enjoyed the car again.
Some people persisted with Pirellis though and tried to argue it out with Audi. In terms of the specific tyre and batch, I can't remember, but like I said there's a massive rabbit hole to wander down with the whole topic on here in past threads if you are ever bored.
