Slight judder/vibration when reversing with full steering lock applied...

[Jonny]

Is this normal on the D3?

When performing a 3-point turn, reversing under full steering lock produces a mild but noticeable vibration or judder.

I've noticed it on both of the W12 cars I've test driven over the last few days. One being a 2005/55 car with 106000 miles, the other a 2005/05 car with 99000 miles.

I've experienced similar, albeit far more pronounced, when manoeuvring a Mitsubishi L200 on dry tarmac having neglected to put the transfer box in 2wd. So i wonder if the milder effect in the A8s is just a quirk of the Quattro system? Or if both cars have had a fault which causes this.
