I want to do this myself, just don't want to blow it and end up having the car down to run around or have to order a part without a loaner which the dealer who's gonna charge me up the butt to do it for me will offer and honestly having the dealer tech(s) do it doesn't really give me piece of mind. Lol this effin sucks big hairy slippery when wet ball sack.
Hey man,
I had the same thoughts, and my wife's tiguan was showing signs of failure so I finally bit the bullet.
Buy:
1. a new timing cover,
2. permatex ultra black tube of sealant,
3. the updated tensioner,
4. the pulley spacer that everyone talks about (but technically as long as u replace the bolt with an inch or so of gap after u pull the crank pulley, you should be good,
5. and an o-ring for your dipstick (#wht-003-463).
6. the crank pulley bolt (not necessary but def recommended)
If you dont have an impact wrench you should get one. If not, you'll have to buy the special pulley spanner wrench. Thats it.
If you have the stock IHI, you'll have to take the outlet nozzle off as well to get the timing cover on and off.
Its not too bad once you start, just realize you're tearing the whole passenger side of the engine bay down. As long as u've planned far enough ahead to have read this DIY, you should be good.
