yeah, sounds like a transmission fluid issue (check level/condition!) or potentially early signs of a Mechatronics Unit problem. That's a common culprit for those symptoms in VWs of that age. Get it scanned for codes, even if no light is on!When driving my 2010 Tiguan, I've noticed it feels sluggish shifting from 2nd to 3rd gear, it feels like an intermittent issue, what could be up?
