i have a 2001 vw beetle. it is a 2.0, automatic transmission with no other issues besides it going into limp mode when it's raining outside. however, i had to have the flex pipe welded and i believe there is whole in it.. i'm not sure if that is the cause of the vehicle going into limp mode. when in limp mood, the engine light starts blinking and my car will only go about 5 mph. when this happens i restart my car after a few minutes of letting it sit and it's like nothing ever happened with the car. i have no idea what could cause the issue..
