My wife got her car inspected and oil changed today. She has a 2004 VW Beetle Convertible with the standard engine, automatic. She calls from the road. Says the car has been sluggish ever since she picked it up and smoke is now pouring from the exhaust pipe. I go out and drive it home. No indicator lights were on. Oil looked normal. No signs of overheating. Car is definitely sluggish and may be over revving some. But when you put the pedal to the floor white steam billows from the exhaust pipe and the check engine light comes on. When I take my foot off the trottle it takes a few seconds but the steam clears and the light goes out. It's going back to the shop in the morning but anyone have any thoughts? I don't think its related to the work that was done but there checking it out just to be sure before I take it in to the dealer.
