This OEM replacement ballast replaces the Bosch AL 1 307 329 115 and 1 307 329 293 headlight control modules — as fitted to Audi, VW, Mercedes-Benz, Skoda, and Seat vehicles from 2004 to 2010.
Plug straight in — no coding, no rewiring, no modifications required. Restores reliable, flicker-free operation to your factory D1S, D1R, D2S, or D2R HID xenon headlight system.
Common symptoms of a failed Bosch AL ballast: one headlight flickering, failing to ignite, or a dashboard headlight warning. If the globe has been ruled out, the ballast is the most likely cause.
1 x Ballast unit. If both headlights are affected, add 2 to your cart.

Always verify by matching the part number on your original unit before ordering.

Is It the Ballast or the Globe?
Before replacing the ballast, swap the working globe from the opposite headlight into the non-working side.
If the light works with the known-good globe, the original globe has failed — not the ballast.
If the light still fails with a known-good globe installed, the ballast is the cause and needs to be replaced.
Flickering briefly before shutting off, or taking several attempts to ignite — this is a classic ballast fault, not a globe fault.

Will this fix my flickering headlight?
