Whilst driving to work yesterday my engine management light came on. I phoned Audi Roadside Assistance who sent a mobile Audi technician out to me within a couple of hours. He plugged his laptop in, found the fault (a temperature sensor had broken, or something) and replaced the part on the spot. All for free. It's things like this that make me glad I paid extra to buy my S3 from an Audi main dealer. I have to say the warranty work I have had done under Audi Approved has also been generally excellent and has almost made up for the inflated dealer car price.
