Been driving round today and had a squeaking from the wheels which got worse the faster I went

Just nipped out for a takeaway and the squeaking stopped but a load of lights came on on the dash with ABS, Steering and stop start all messaging in the DIS as having issues.

Any ideas before I book it in at Audi under warranty. It's a 2012 Black Edition 2.0 tdi

Cheers peeps

I wonder if I can get a s****y courtesy car !
