My 99 gti seems to have a few problems im not too sure about. The first one is the idle. Though this doesnt seem to effect the car is idles at 500 instead of 750 and sounds a tad lumpy. it doesnt seem to effect acceleration though and drives ok.
Second is when im driving the engine seems to make a ticking/rattling noise, this seems to drop off when accelerating less but as soon as press the accelerator further the noise picks up again. Baffles me as ive checked oil levels and they are fine.
Any help with either of these would be great. Thanks

problem one: check your idle control valve and give it a clean, failing that have a play with adjusting the idle using the clip thing on the throttle body.
problem two: sounds like you have the common manifold rattle, try having a search around there's lots of people with this problem

Issue No2 could also be noisey tappets.

If it was tappets wouldnt you get this at idle and also from revving the car at neutral, which it doesnt?

My GTi was a bit tappy from cold at times.
Also as stated above, the exhaust manifold is a known issue, but fairly uncommon. I changed the manifold clamp & it sorted it out.
