Low speed graunch

At low speeds (sub-20mph) and with lots of steering lock, there's a bit of a graunching noise coming from under the car - a bit like driving with a welded diff.
Is this anything to worry about? Does it suggest I need to change the oil in the diffs? The Torsen unit is sealed for life, I believe?
It definitely isn't a wheel bearing.

Mine does that mate, but all my cars have made some sort of noise on low speed full lock. I put it down to the 235 width tyres rubbing a little and I just dont use 'full' lock anymore
( but I could be wrong ? )

It's definitely not the tyre rubbing, and it's not from the front - it's the centre/rear.
It could be a "feature" of the S4, or of 4WD in general, but because I bought the first one I saw.....

Can't ever remember mine doing that! Think I would get it checked out mate.

On full lock at less than 5mph I get a feeling like the diff is locking I assumed it was normal....

yes sounds a bit more serious, maybe just be oil levels fingers crossed n all that

Mine does this all the time coming out the drive, normal for a quattro, nothing to worry about Dan

Cool, I had a feeling it was a 4WD "feature".
Might check the diff oil levels anyway, before taking it round Bedford GT in a couple of weeks.
