I would recommend buying a TB kit from one of our trusted vendors, that way you get everything you need without having to deal with part numbers or the dealer.

Second this. The reputable vendors on this site have already done the legwork for you. You won't be able to save money by piecing together your own kit either

Hopefully you've found the A4 timing belt pdf here... one of the best step-by-step guides there is, and I believe it has the complete list of torque-to-yield bolts and other disposables.

If not, linked in my sig.

Haha do you know how tty bolts are designed and engineered? I do. It doesn't take an engineer to understand in certain applications, you're gambling. $50 in bolts sure beats the alternative...new top end and a lot more time and money wasted. So I would say, if you ignore these, you actually have more money to burn, when something fails.

Thanks Vince.
I do have that on my computer.
I just used it to verify/update the list showing what the old numbers were.

Still have several numbers from the dealership receipt
that I don't remember what they go to.
Mostly roller, tensioner studs and nuts.

The dealership did sell me some bolts that didn't fit anywhere near the timing belt.
I'm also trying to sort them off the list.

Bolts related to the motor mounts are probably the really critical ones. A dropped engine will ruin your day, and it absolutely happens. :)

Likewise with rollers and studs... same bad day if they let go.

Unless you plan to change-out the Crankshaft Seal (which is not on your list), there is no need for a Crankshaft Bolt.

I agree with the others, get a "kit" from one of the reputable vendors that support this Club.

Agreed. That first number started out as a possible crank seal number.
More likely a cam seal, from my notes.
Not sure if it's the same as the crank seal on a TDI.

I got a TDI that needs a timing belt change.
It came with a contitech timing belt kit.
These bolts aren't in it.

I'll order up both studs and see where they fit.
I think the nut is the same for both idler/tensioner studs.

I see no reason to not replace any fasteners specified to be replaced. If your 3 IP pulley bolts are gold, not silver, they are re-usable.

I second replacing the bolts. I had one of the engine mount bolts break on me after doing a timing belt change where I didn't replace the bolts. (Didn't know I needed to...) I then had to replace the engine mount block that bolts to the engine.
