Hi who came up with the immaculate diagnosis that the battery is fine, the times I have seen this and when the car is plugged and scanned it throws up a load of non communication faults caused by low voltage, you really do have to have it plugged in and check the date on the battery, the electronic steering uses a lot of voltage.

Eventually, having considered the problem of not getting ‘centred’ on the steering wheel plus getting the fault light on the electric steering, I put the SQ5 into the main Audi distributor. They had to reboot/ reset the software/limits on the steering. £190 later and it’s been put right. It seems to be a weak point on these cars. No assistance whatsoever from Audi/VW U.K. It was two days outside of its main dealer warranty. You make your own decision on how you see this.
With any electrical faults especially if the car has electronic power steering it's worth getting the battery checked as a failing battery can cause all sorts of electrical issues.
