I have noticed that when I put full, or nearly full lock on the RS and drive off, I get a "grating" sound and it feels as though I am running over gravel. Is this normal? Has anyone else experienced this? It mainly happens when the car is cold.

I think you may be experiencing the same as an R8 and my C5 RS6: viewtopic.php?f=38&t=113409

It was -3 here and had a weird grating sound as i was pulling out of my road. It stopped pretty quick but not sure what it was.

I get this in both my Porsche and also Abarth 500 - most noticable when the (summer) tyres are cold. I think it is just a function of wide tyres on a tight steering lock.

Ah, that sounds plausible. Good thinking.

Yes i believe this is correct, it always happens on our cayman, i used to think there was a problem but it is just due to the point made above. ^^^^^

OK Guys Thanks, seems 4 wheel drive has something to do with it also, as all 4 wheels are not alined at very low speeds according to Audi UK.
So it is not broken then,

Thanks for the replies guys, its normal, phew

Tends to happen most when tyres are cold and with a damp surface. The noise is the rubber losing traction on the outer front wheel relative to the turn

Get that I in my b8 too, standard diff/4wd character
