The halogen headlights on the T1 Touareg are not good and, on wet roads at night can be downright dangerous.
Do get them properly adjusted but beware, you need to use plenty of WD40 or similar first and the plastic bits may break but if they do, just take the nbits to your dealer and get the new parts - they're a tenner or so.
See post number 4 for the headlight adjustments [take no notice of the xenon words]. The pictures shown are for the nearside headlight on a RHD.

You'll need to work it out for yourself from this for the offside!
Here's how you get the lights out including pictures:

I strongly, very strongly, suggest the best upgrade to go for is a set of HIDs.
Buy them from http://www.hids4u.co.uk/
You need H7/projector/5000K/55watt/CANBUS and use STRATHY as the discount code at checkout for 25% off.
They take an hour to fit.
You will then need PIAA Extreme White in the main beam to match. Not cheap but mine lasted 8 years and were still going strong when I moved my T1 on.

You'll need to go on e-bay for a manual.
Do take time to read the buying a used Touareg thread in my signature. You will learn a lot about the car you have just bought and probably save money later too.
