Did mine a month ago, make sure you get original VW gasket set & new gasket for the large to small manifold & make sure it is for a 50mm inlet. VW cocked mine up and gave me a 42mm one so I had to use the old one.
1 Unplug the ht leads & unclip the plastic tidy casing and fold them back out of the way. You dont have to remove the plugs.
2 Unplug and remove the ISV & pipes and move them away from the top of the engine.
3 Disconnect the plastic inlet pipe from the throttle body, and the electrical connector to the throttle body.
4 There are steel brackets holding the manifold up off the back of the engine, I found it best to unbolt these from the engine block, x 4 bolts, awkward to get to but not too bad.
5 Disconnect servo vac hose from the RH end of the manifold.
6 Unbolt the large inlet manifold from the small manifold and then fold it over towards the right, there's no need to disconnect the throttle cable. just rest it all on something soft to protect the bodywork.
7 The rocker cover will now be fully exposed and easy to get to. I would suggest you immediately stretch a couple of layers of clingfilm over the exposed inlet manifold tubes so you don't drop anything down them.
8 Undo the 8 bolts holding the rocker cover down and remove it and the rubber gaskets & half moon gaskets....
9 Clean up all the mating surfaces and refit the new gaskets.....
Don't do what I did, I got carried away and fitted the gaskets, cover all bolted down etc. and I'd forgotten to put in the new 'half' moon gaskets. If VW had given me the right manifold gasket I'd have had the whole lot back together and started it up without them

:embarassed:

Its only cos I went back to the gasket box to check the gasket description that I spotted the missing half moons in the box....... arrghhh!!! Had to undo it all again to pop them in. Mind you after all that I've still got a tiny weep from the half moon on the gearbox end!!!

Hope this helps.
