Touareg V6, 2005:: I tried to open the door using the remote and nothing happened. After entry using key, tried to start car, nothing, and key wouldn't release. Battery was dead, this is a car with 216 miles on it. Put charger on battery and was able to charge battery adn start car. Drove to dealer and noticed the dif. lock was flashing and oil pressure gauge wasn't showing any pressure. Upon arrival and re-starting car to show service the problems all was find. Left car at dealer and waiting to see if they can find anything. Dealer has called and said battery was drained but didn't show any codes as to why. Will post again and let you know what they found.
