A8 2.8QS '52 plate engine management light

[Titan]

Well the car eventually made it into A4Audi. I didn't have time to take it in so my Mum popped in with it today and they reset the light. They said they knew the car well and told her the light had probably come on as the car hadn't been driven much recently? Fair enough.
They didn't charge and the car has is still driving fine so fingers crossed it stays out.
That's the kind of customer service that will make me take the car back for all future work.
