I just bought a used 2008 Jetta S with only 16k on it. The other day, after multiple stops turning it on and off at different places, i started it up adn the tachometer stayed at zero along with the oil pressure light coming on. I restarted the car, and both of those went away, but then i noticed once i had it in drive, it was stuck in third gear. Tiptronic wouldnt shift it either. Restarted it again, and havent had an issue since. The Autobarn VW of countryside, illinois where i bought it tells me they can't find anything, but it could still have an isssue. what should i do
