Yes, but we could continue in that same vein for all momentary problems couldn't we?

I Don't know whether I mentioned that last year when I started the car, (can't remember exact details), the ESP light came on and would not go off and the power steering wasn't working either.However, I turned the engine off and a few moments later everything was OK. I never mentioned this to them either. I'll just sell the car back to them when I get fed up with it and let them find these things out for themselves or the person who then buys my car off their forecourt.

Cars, like people often throw up idiosyncracies that don't have a true explanation and garages especially repeat their same old mantra that "we can't find anything wrong at the moment, Sir/Madam but do come back again if you have problems."
