Hi guys
My 8L S3 is doing some odd-things with the Haldex Diff - it's binding up the read wheels - a fuse pull to disengange the Haldex controller fixes this, so it's probably a controller. BUT also, making a horrible grinding noise at speed.

I suspect a new diff is in order.

Anyone come across this? Anyone got a Mk TT or S3 second hand diff?

Thanks
