Default Injection Pump Sprocket New Bolt Torque?

I'm replacing the timing belt on an ALH engine TDI this weekend. I have the Dieselgeek "Delux" kit with the needed new bolts, including for the injection pump sprocket. What are the new IP sprocket bolts torqued to? I just read the timing belt "How to" and did not see this mentioned. I take it that the new bolts are not "torque-to-yield" and thus do not require the last "1/4 turn". Is this correct? Also, after the initial tightening of these bolts, I then check the timing with VAG-COM. I can loosen these bolts (reuse them) multiple times correct, since they are not torque to yield, in order to fine tune the timing, right?

Thanks.

I don't know the answer to the torque question right now, but will check my manual tonight.

I do think they are tty bolts. The procedure is to do the VAG-COM tuning with the old bolts, then lock the IP pulley down by replacing with the new one at a time.

edit: My B4 manual says 18 ft-lbs. I'll bet the A4 is the same but will check.
