Installation & Fault Diagnosis

Professional installation is recommended. Diagnose the fault and inspect the light guide, connector, wiring and headlight for moisture before replacing the assembly. A damaged or discoloured light guide can leave the DRL dim or yellow after replacement. Follow the vehicle-specific workshop procedure for mounting, sealing and heat transfer; diagnostic checks or vehicle-specific setup may be required.

For fitment help, provide your original module reference and clear photographs of its board, connector and headlight label.

Frequently Asked Questions

Which headlight type does 8V0998473A fit?

This is the left DRL and turn-signal LED module for the matching Audi A3 / S3 8V standard LED headlight (non-Matrix). It is not for xenon/bi-xenon or Matrix LED headlights. Match the complete 8V0998473A reference, B011782-A board, nine-LED layout, eight-pin connector and mounting points. Vehicle model and year alone do not confirm fitment.

Is compatibility the same as 8V0998473 without the A suffix?

No. The A-reference is for the matching standard LED headlight and combines white DRL with amber turn signal LEDs through an eight-pin connector. The no-suffix 8V0998473 module is for xenon/bi-xenon DRL/position lighting and has a five-pin connector. The 8V0998473B Matrix LED DRL module has a two-pin connector. Match your original module and headlight equipment.

What functions and LED layout does it have?

It provides white daytime running light and amber front turn signal functions. The photographed board has nine emitters: three white-light LEDs and six amber LEDs. It is not the dipped-beam or main-beam light source.

Which side does it fit?

Front left, viewed from inside the vehicle facing forwards. On UK right-hand-drive vehicles this is the passenger side / nearside. Left and right modules are not interchangeable.

What are the dimensions and what is included?

Dimensions are length 85 mm × width 55 mm × depth 32 mm. One left-hand assembly is supplied with LED board, eight-pin connector, metal housing and perimeter seal, as pictured. The complete headlight and vehicle wiring are not included.

Will a new module fix every DRL or indicator fault?

A failed module can cause a dim, flickering or non-working light. Moisture, damaged light guides, wiring and connector faults can cause similar symptoms. Diagnose the fault before fitting and follow the vehicle-specific workshop procedure. Coding-free installation is not guaranteed.
