S3 8P rear locking of wheels

[Carl2019]

Hi all new to the Audi world last week purchased a 2010 S3 8p drove fine home and during the week the rear wheels locked in and after couple minutes released later in the week it done the same again this time proper locked up car got fsh and had no fault codes on dash so assuming it’s mechanical issue has anyone had this or know what it maybe? No obviously leaks either.
Cars in garage apparently on cold it’s driving fine well baffles any help would be awesome

Thanks in advance

Get it scanned with vcds most fault codes dont bring up any warning light on the dash
Also try the 8p section you will get more replies there
Could be brake or Haldex related
