Hi Friends, my first post so I hope I get it right!
I have a Mk4 Golf s tdi. Its been trouble free since 1999, but just lately it's been easy to engage 3rd when engaging 1st. The book says it's a dealer adjustment, so gives no info. I'm a retired mechanc (76) and would be glad of any advice if it's diy possible!

Thanks,
Helloern
