I know this is not your problem, but my low beam stopped working, both bulbs failed, no burn marks or broken element. Just had to tell someone

SOURCE: no low beam head lights

If you just want to replace the bulb yourself, this is a good website.

If the website does't get your headlight fixed... You might have a blown fuse. It could be in the IPDM E/R location under the hood. This is next to the coolant bottle. Remove the coolant bottle with two screws and lift the cover to the IPDM E/R. Just set the coolant bottle aside for now. The low beam fuses are 49 and 50. They are 15A fuses. To be more precise, they are located on row 2, columns 2 and 3 (column 1 being closest to the fender of the car). Hope this helps.

The problem is in the high beam switch assembly which also houses your turn signals and possibly cruise control, and yes, I'm sure. There are some electrical contacts in the assembly which dis-connect the low beams when you put the high beams on. Constant use of the high beam switch will create arcing on the low beam switch which makes the contacts not conduct electricity anymore. The daytime running lights send power to the low beams on a separate circuit. .

The repair is to either replace the assembly, $300 at dealer, $100 or less do it yourself, or take the assembly apart and clean it for free. (2 hours or less)

P.S. If you own a VW, especially around model years 1999 to 2004, there is a rare but devastating problem with engine coolant being literally pumped through all electrical parts of your car.... destroying it. Repair cost = $8,000. It is called coolant migration. Check your VW right now (takes two seconds, literally), and do a two-minute procedure to fix your car to prevent the problem here: http://www.myturbodiesel.com/1000q/multi/coolant_migration.htm
