Technical Specifications

Vehicle Compatibility & Headlight Checks

For matching Audi A3 / S3 8V facelift xenon / bi-xenon headlights with LED DRL. Fitment requires the complete original 8V0998474 reference, B101139-A board, five-pin connector and matching mounting points.

Vehicle model, engine, trim and registration year alone do not confirm compatibility. Check the headlight label and original module before ordering; the model-year guidance below is equipment-dependent.

Installation & Fault Diagnosis

Professional installation is recommended. Diagnose the module before replacement and inspect the headlight for moisture, damaged wiring, poor connections and a scorched or discoloured optical light guide. A damaged light guide can leave the DRL yellow or dim after replacing the LED module. Check the perimeter seal and follow the vehicle-specific workshop procedure for mounting and heat transfer. Diagnostic checks or vehicle-specific setup may be required.

What’s Included

One HIDS-DIRECT right-hand module assembly with LED circuit board, five-pin connector, metal housing and perimeter seal, as pictured. Complete headlight, xenon bulb, ballast and vehicle wiring are not included.

If you need help confirming fitment, contact HIDS-DIRECT with your original module number and clear photographs of the module, connector and headlight label.

Frequently Asked Questions

Which headlight type does 8V0998474 fit?

It is the right white LED DRL and position-light module for the matching Audi A3 / S3 8V xenon / bi-xenon headlight. Match the complete original 8V0998474 reference, B101139-A board, five-pin connector and mounting shape. It is not for standard LED or Matrix LED headlights; the A-version and B-version modules are not interchangeable with this part.

Does this module operate the turn signal or xenon bulb?

This module supplies the white LED daytime running light and position / side-light function in the matching headlight. It is not the amber indicator module or the xenon ballast for the dipped or main beam.

Does it fit the left or right headlight?

This module fits the front right headlight. On UK right-hand-drive vehicles this is the driver side / offside.

Do the vehicle dates confirm fitment?

No. The dates provide model-year guidance for matching facelift xenon applications, not guaranteed fitment for every vehicle in those years. Match the complete original 8V0998474 part number, B101139-A board, five-pin connector and xenon / bi-xenon headlight type. Vehicle model and year alone do not confirm compatibility.

What are the dimensions and what is included?

The module measures 84 mm long × 44 mm wide × 40 mm deep. One HIDS-DIRECT right-hand assembly with LED board, five-pin connector, metal housing and perimeter seal is supplied as pictured. The complete headlight, xenon bulb, ballast and vehicle wiring are not included.

Will a replacement module fix a yellow or dim DRL?

A failed LED module can cause a dim, flickering or non-working DRL, but a scorched optical light guide, moisture or wiring fault can cause similar symptoms. Check the light-guide entry surface and seal condition and repair underlying faults. Professional installation and diagnostic checks are recommended; coding-free installation is not guaranteed.
