Precision Control for AUDI Matrix LED Lighting

This aftermarket LED headlight ballast and DRL control module replaces failing driver units on 2017–2019 AUDI A3, S3, and RS3 models equipped with matrix LED headlamps. By regulating the 12V DC and 42V AC input cycles, the regulator eliminates flickering, restores stable daytime running light output, and shields sensitive headlamp circuitry from voltage fluctuations. Built to match factory connector geometry and housing dimensions, the 35W component bolts directly into your existing harness without wire splicing, delivering a cost-effective solution when complete headlamp assembly replacements exceed your budget.

Benefits & Practical Tips

  • Restore consistent DRL operation and eliminate unpredictable beam dropout caused by degraded ballast circuitry.
  • Replace only the defective module rather than the entire headlight housing, significantly lowering diagnostic and repair expenses.
  • Verify your original part markings before fitting—the left side uses 8V0998473B (B011784-A) while the right side uses 8V0998474B (B101785-A). Wiring schematics are not supplied, so professional installation ensures proper pin alignment and IP-rated seal retention.
