Flicking main beam

[phunder]

On my 04 Cayenne S I've notice that sometimes the main head lamps would flicker very slightly - doesn't happen all the time just now and again - and to no particular light. On two occasions I saw a warning for "dripping blub". The whole gets reset when I restart. It's not a driving problem - more ignoring than anything else. Is there a quick fix .i.e. reprogramming?

Thanks for anyfeed.

I'd guess a bad connection .. go bounce the Cayenne around a little and work everything in or out...Mine did the same a few months ago when we went on vacation for 4 weeks, bounced it around a few speed bumps and corners and it went

If you remove the headlight assembly you'll see that it sits inside of a black plastic carriage. There are two bolts (10mm, IIRC) that secure this carriage. These bolts can become loose very easily. If they are loose, they allow movement of the entire unit, and result in flickering and in error messages. I'd start there, see if they are loose and tighten them up. Hopefull that will solve your problem and eliminate the error messages.
