Noooo! Having just recently "facelifted" my GP0 with the DRLs I was hoping that they would outlast the rest of the car and that I would never need to worry about LEDs burning out. Seems not to be the caseI noticed last week that one (maybe 2) of the LED components in one of the front headlamp DRL on my MY2008 Phaeton have failed, so it looks like the Phaeton is missing a few teeth..
Sorry to say, but the LED strip is VERY integrated with the headlight unit. There is absolutely no way to replace the LED strip (or individual LEDs for that matter) unless you find a way to get off the headlight plastic lense. "Officially" it is sealed for life and I would think twice before attempting taking it apart. I have had some success (with other cars) by removing any visible clips, then placing the headlight into baking oven (at about 100 degrees celsius) for a while and then ripping off the lense with force as the glue has given up somewhat. It is a NASTY job.1)how much requires replacement
This involves replacement of the headlight. Bumper needs to come off first. Can be done yourself and has been documented on the forum. There are used headlamps on sale on ebay.de and allegro.pl. I am suspecting, though, that some of them may have the same issue... Fortunately, a used lamp is not too expensive (seems to go for around 250 euros without controllers) so you just might take your chances with a used one...?2) Any possibility this is a DIY task.
