Hello Ritchie.

Who done your alternator replacement? If your garage says the warning lights are due to an alternator issue, shouldn't you just return the car to where you got the alternator fitted?

It's difficult to give you any meaningful advise without knowing what trouble codes are in the car. It could just be that the basic setting of the steering angle sensor has been lost when the battery was disconnected to fit the new alternator. Normally the sensor relearns on it's own after you drive a few yards but not always. Sometimes you have to reset it using the diag machine. If you can post back with some codes someone might be able to better advise you.

Hello again Ritchie.

Well, I'm sure you wont be surprised when I tell you that the fault codes relate to an alternator issue. I wouldn't have thought an alternator fault would have caused the ABS/ESP warning lights to come on but a few other forum posts confirm that it does. Since the fault only appeared after the alternator was replaced, I think either the DF connector (2 pin plug) hasn't been connected properly or the alternator itself is incorrect/faulty. There are different types of alternators available for Audis. They look the same and the wiring connectors are interchangeable but they have different electronics inside. Maybe you have been supplied the wrong unit for your car.
