So besides disconnecting all the hoses and pipes needed to remove the cylinder head, and of course getting the new stretch bolts, are there any special procedures for making sure that everything is timed correctly? AFAIK on the 1.8t you set the cylinder #1 to TDC (then turn the crankshaft back a little bit) and you make sure that the grooves in the camshaft gear (in the rear) match up with the camshaft retainer arrows. Just wondering how the 2.0t differs from the 1.8t.

Are there any other stretch bolts needed if I will be removing the cams to clean out the cylinder head? Thanks to whoever can answer my questions.

I haven't dealt with 1.8's before but i can tell you that on 2.0t you need to line up exhaust camshatft sprocket with the mark on the rear timing belt cover and the crankshaft pulley mark with the mark on the dampner pulley behind the Pulley itself.

YOU DO NOT need to remove the cams to clean the cylinder head, unless your changing one of the camshafts you should not touch the camshafts, if you do have to change one of the camshafts then you need to remove the cam girdle/cage which it has 20 something TTY bolts (stretched bolts).

My goal is to refresh all the valve stem seals with the cylinder head removed, and as well as clean all and lap all the valves and seats which would require removing the camshafts. I understand what you're saying - - is that if you line up everything accordingly (exhaust cam & crank marks), and remove the cylinder head without shifting anything, but I'd like to take the cams out and know how to correctly time the 2.0t engine from scratch.

Well, in that case your timing on the camshafts its irrelevant since your moving everything out, as long as you line up everything back together then you should be fine. I do want to let you know that when removing the camshafts technically speaking you have to remove the timing chain in the back, in order to remove the timing chain you would have to remove the cam Adjuster and the tensioner. If you haven't done this before i recommend you to get a repair manual because your in for some serious work, and some special Audi tools are required if you never done this kinda of work.

I totally agree with you. I'm doing the research now, finding out what tools I need, and the correct procedure for matching up the cams. Any idea what kind of tools are required besides the exhaust cam gear holder?

Correct me if I'm wrong, but I'm led to believe that the timing procedure is to first make sure that intake and exhaust cam lobes are facing towards one another, make sure that none of the cylinders are at TDC, install all the seals, cam girdle, chain + tensioner, and then install the exhaust cam gear. From then on match the exhaust cam to the upper timing belt cover mark, set the crank to TDC #1 cylinder, then install the timing belt components.

Correct, what you want to do is set your engine to TDC (make everything is lined up) then use a white permanent marker to mark your cams against the cam girdle/cage, this way you will know exactly where they should be when putting them back in.

You will need a special Audi socket to remove the Adjuster bolt, see the link it http://workshop-manuals.com/volkswagen/golf-mk5/power_unit/4-cylinder_injection_engine_%282.0_l_engine_direct_i njection%29/engine_cylinder_head_valve_gear/valve_gear/removing_and_installing_camshaft_adjuster/

If you're taking the timing chain and tensioner off, I would replace those as well. Eventually that timing tensioner wears out and cause it to tick. You'll want to replace the chain as well as they stretch over time.
