Hi Thomas, I've got myself a 2013 Allroad and just had the complete set of front suspension arms replaced and have the same error as you, prior to this it was all fine. Found the part numbers already but there appears to be lots of non OEM sellers of this part and was looking for your recommendation as you have done this recently.. I'm not a million miles away from you either in Midlothian.
Any advice you can give would be much appreciated. I've got full VCDS so can do scans etc..
Cheers
MrB.
