I am new to this site and am hoping someone can help me out or even lead me in the right direction. I have a 2008 touareg V6 and the problem started about 2 weeks ago. While driving the vehicle during normal conditions the RPM s shot up to about 5 grand while the MPR dropped to about 10 and wouldn't go any faster making me have to pull over and turn the vehicle off. After starting the vehicle back on it drove fine for about another 1/2 mile then did the whole rev thing again. I was eventually able to make it home after taking it to a repair shop twice they said it was fixed and it was due to a vacuum leak. Well, less than a day and it did the whole thing all over again. To be able to make it home this time I switched the tranny in to "sport mode" and found that the gear select was NOT showing up on the instrument panel and the vehicle drove as if it was still in "automatic" and drove fine. So when I have to drive the vehicle as long as I put the gear select in manual it will drive fine without me having to shift the gears. I have been trying to find answers as to why it may be doing this and believe it is a bad TCM. any thoughts and help on this matter will be greatly appreciated.
