Theres some pdf files on gtiroz, There is one that gives service data specifications or something, mainly plug gaps, geometry settings, belt tensions, torque settings etc,etc.
At the top of this section there are some files from the manual.
If you want to carry out a service yourself, just look at doing transmission fluids (gearbox, rear diff, transfer box), engine oil and filter, plugs, fuel filter, coolant, pads and discs ( dependant on condition ), brake and clutch fluid, power steering fluid, tyre pressures, washer fluid.
Change dizzy cap and rotor head, clean out intercooler and oil seperator if you can be @rsed and check condition of cv gaters, belts and dampers for any wear and tear.
And look for any oil leaks anywhere from the engine.
Thats more than most garages are going to do anyway. 8)
