I have an 06 vw jetta tdi that is going into limp mode. I never have a problem with it while driving it in town but its nearly impossible to drive on the highway. As soon as I hit 75 mph or really give it gas on a hill all power is lost. Turning the car on and then off fixes the problem. The check engine light does come on but goes off after a few days. The car seems to be running fine other than this. Not really sure what is wrong maybe n75? Trying to avoid the dealer at all costs.
