I've had my 04 GTTDI for just under a month, recently, on journeys over about 20 miles two amber warning lights have come on. My Traction control/ESP light and my ABS light. When I turn off the car and turn it back on they disappear and dont come on at all when I'm on a short journey. I've booked the car in for Friday with VW, but was wondering if any of you can shed some light on what the fault(s) may be. Luckilly, the garage I purchased the car from gave ma a 3 month warranty with the car, so it won't be my money, but still interested to hear your views.
