COLATA CHANGE A4 2.0 TDI 2005

I would like if it is possible that someone could help me find the A4 2.0 TDI workshop manual of 2005 that came out with some cylinder head and I think it has touched me at this time (120000 km) and to solve the fault with more guarantees or if anyone is clear to be able to get me out of some doubts (Eat the distribution without having to mark). Thank you and greetings to the foreros.

It is always advisable to mark the distribution before Scarla is much easier to mount it later and do not run risks that the vehicle will be brought or drew, marking is easy, with a liquid corrector, of those that serve to erase paste or bowling pencils, marks two teeth of the cam and the belt where those teeth go do the same with the crankshaft, if you have double leba.
