Need help with Headlight Brightness Issues (Dim)
Hello guys
I own 2008 3.0TDI audi Q7 4L I am having an issue with my headlight brightness which is very dim. lets say HID Headlight requires about 45,000 candela and my i have replaced bulbs (it did happen even before i changed headlight bulbs lots of times) and one side come out with 12,000 candela and the other side comes out with 7,500 candela. I was trying to figure it out so hard that why this happens and even the Audi Service Centre couldn't figure excpet they said we need to test all the power roads. (electrcial test) I've replaced the Alternater recently too. If anyone had same issues.. please help me to fix my car :) |
Sounds like the HID Ballast is going out.

It's very common for ten+ years old vehicle with HID + Lens. I am almost sure that the problem is in dirty lens behind the glass...
Some stores sells even entire projector (reflector + lens) : Audi Q7 Xenon Headlight OEM HID D1S Ballast Bulb Control Unit Module Projector Reflektor Bowls Change or https://www.aliexpress.com/item/FREE...676802272.html |
Generally dimness is the ballast, a color shift (toward red/ pink really) is the bulb. Generally. 2008, its about time for both probably, but try bulbs first.

Hmm weird

Watch this https://www.youtube.com/watch?v=BX2vQSiVE80 The Ballast is the aluminum box on the underside of your headlight.
