My old mk6 went through 5 stalks in 6 years. Take the stalk off and spray with contact spray.
Also the back light connections are terrible on these as i was forever having problems with the rears.
Do the same with the rears give all the contats a good clean and a play about. Thake the connector off the rear lights and check the pins arnt bent.
They can blow fuse boxs as mine did and had no headlights. Just take fuse box off dead simple and get another from scrappy be £15/20 max!

If you need anymore help just say!!
