I did buy the 2002 A6 Avant 4.2 Sport (86k miles) and have really enjoyed it (but that's another story).... so far I've done about 500miles a mixture of Motorways, A&B roads and town.

All these miles have been done during the day with no headlights (Xenon) on.

Yesterday Mrs M suggested we pop out to see a house (yes we're house hunting) and it was her 1st time in the car.

So the first time I've driven it with lights on, the ESP warning light came on almost imediately and the engine started to not run smoothly. It was the 1st time for both (esp light and not smooth) so we pulled over at a garage and after a scratch of heads wondered if we had a slo puncture so checked the pressures... they were all out and all over the place (FL-38, FR-36, RL-34, RR-32).... started up (no ESP light) and drove some more and after a while the light came back on and hte engine stopped running smoothly.

Today we've been out (100+ miles) and no ESP light and back again as smooth as silk... even turned the headlights on for part of the trip!!

So does anyone have any ideas or do we just chalk it up as "one of those things that sometimes happens with a car 8 years old" but keep an eye on it?
