How to Change the Oil Dipstick Tube on a Volkswagen Jetta | More info
This video shows how to change the dipstick tube on any 2 liter VW engine, not just a Jetta. VW uses a cheap plastic which eventually breaks. I bought the replacement tube and dipstick from Rockauto for about $3 each, but I had to pay for shipping twice because they don't stock the two pieces in the same warehouse. The total was about $18, which was cheaper than buying them at a local auto parts store. The part number for the tube is 06A103663C.
