We've got a new A3 2.0T S-Line - had it for about a week (the car is 3 months old). Everything's been fine until last night when I went to pick up my other half from the shops. Had to sit there for a while, so I had the ignition on listening to the radio. *Eventually*, she turned up (you know what girls are like) so I started the car and set off. As I did so, it took a while for me to realise the steering was really heavy - as if there was no power assistance. Just as it dawned on me that there was no power assistance, there was a beep and the DIS went red saying there was no oil pressure! Eeek! Anyway, switched everything off, waited for 30 secs and restarted and everything was fine. Has anybody had this before? Is it a 'feature'? Or should I be phoning the dealer already?
