Was told this is an ongoing problem with 2000-2003 era New Bugs. No recall or written Technical Bulletin was disclosed by the local VW dealer on this, but orally they chirped like a flock of birds! Alternator & grounding was fine. Solution: Use ONLY OEM headlamps! Yes, use ONLY the German bulbs!! They WILL supposedly last much longer than aftermarket ones. Of course, make sure you don't ever handle the lamp with your bare hands, the oil from your body will prematurely burn out the lamp. So it is written, so I shall try this...
