this morning i started my 2000 passat and it fired right up. let it idle for about 20 minutes, moved it not even 25 feet and shut it off. when i went back to start it, lights came on, dash seemed fine, no juice. thinking it could be the starter, that or its too damn cold for my Vw. battery has life and nothing registers when i go to turn it over. its in park and while i am still able to shift through each gear, i cant seem to fix this problem on my own. any suggestions?
