This is the direct OEM replacement for the AL Bosch Gen 3 (1 307 329 082) headlight control module. It is fitted to a vast array of European prestige vehicles from 2000 to 2010, including the Mercedes-Benz C-Class (W203), S-Class (W220), BMW 3 Series (E46), Audi TT (8N), and VW Golf GTI (Mk5), equipped with factory D2S or D1S HID xenon headlights.
It restores reliable, flicker-free operation to your factory HID xenon headlight system. No coding, no rewiring — plug straight in and it works.
AL Bosch manufactured this 3rd generation ballast and assigned it various internal part numbers, most commonly 1 307 329 082 and 1 307 329 074. Vehicle manufacturers then assigned their own OEM part numbers to the exact same unit, such as Mercedes-Benz's A2038209385 and BMW's 63127176068. They are all completely interchangeable, and our replacement matches the original OEM specification exactly.
Headlight flickering, a headlight that won't ignite, or one side that cuts out after a few minutes are the most common signs of a failed ballast. If swapping the globe to the opposite side makes no difference, the ballast is the fault.
1 x Ballast unit. If both headlights are affected, add 2 to your cart.

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 still fails with a known-good globe, the ballast is the fault.
If the headlight works briefly then cuts out, or flickers on startup, this is typically a ballast fault rather than a globe fault.

Yes. AL Bosch manufactured this 3rd generation ballast and assigned it various internal part numbers, including 1307329082 and 1307329074. Vehicle manufacturers like Mercedes-Benz and BMW then assigned their own OEM part numbers to the exact same unit, such as A2038209385 or 63127176068. They are all completely interchangeable and function identically.
This ballast is designed to power D1S, D1R, D2S, and D2R HID xenon globes. It takes a 12V DC input from your vehicle and delivers an 85V AC, 35W output to the globe.
No, this ballast does not fit the W210 E-Class. It fits the W220 S-Class, W203 C-Class, W209 CLK, W215 CL, and R230 SL-Class. Always check the part number on your original ballast before ordering.
If your HID globe is in good condition, replacing a faulty ballast will cure flickering, random shut-offs, and failure to ignite. We always recommend swapping your working globe to the faulty side first to confirm whether the globe or the ballast is the root cause of the problem.
No. This OEM replacement ballast is completely plug-and-play. It connects directly to your vehicle's factory wiring harness without the need for any dealership programming, coding, or modifications.
