when in tiptronic mode, it just displays the gears like you're still in auto. Nothing happens. The check engine light comes on when I'm in neutral, reverse and also other gears apart from D. The car was still driving normally when the AT light was not on. I only had to turn the car off and on again and the AT light would disappear. Would it still run normal if my coilpacks were F^&*ed? I'm looking on the brightside, if the coilpacks and solenoid are faulty then they will definately have to replace them under warranty! On the other hand if that were the case then I Probably won't see my car for another couple of days.....its being trucked down to Gavin Woods down the coast so I guess I'm in good hands. The dealer has been good so far and wants to get this fixed asap. Shit happens
