Audi A3 Headlights: OEM Part Number

Accuracy note: genuinely worth knowing: adaptive or matrix LED headlights on higher A3 trims are significantly more expensive to replace than standard units and often can't be sourced secondhand as easily — worth checking whether your car has this feature (usually badged or listed in the spec sheet) before assuming a standard-trim price applies.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Audi A3 Headlights

If your A3 has factory-fitted halogen headlamp housings, converting them to fit LED bulbs is treated as a definite MOT failure under the current inspection manual — this isn't a grey area or a minor advisory, since a housing designed for halogen doesn't distribute an LED bulb's light output correctly, which can genuinely dazzle oncoming drivers. If you want a genuine LED upgrade, the correct route is a complete headlight unit designed for LED from the factory, not a bulb swap into an existing halogen housing.

Before you buy: matrix LED, adaptive, and cornering headlight systems often require electronic coding to the car after a unit swap, even for a genuine like-for-like replacement — a headlight that isn't recognised by the car's electronics can trigger warning lights or fail to auto-level correctly. Check whether your specific trim has one of these systems before assuming a straightforward bulb-in, bulb-out job.

Audi A3 Headlights: What It Does

On the Audi A3, main and dipped beam bulbs — or LED/matrix modules on higher-spec cars — live inside the headlight unit, angled carefully to illuminate the road without blinding oncoming traffic. The daytime running light and front indicator often share that same housing too, adding complexity to both fitment and repair.

Audi A3 Headlights: Generations, Derivatives & Headlight Type

8V pre-facelift (2012–2016), standard trims	Halogen or Xenon depending on trim and options
8V/8V.5 (2012–2020), Full LED option	Bi-LED projectors with a steady white DRL strip — a genuinely different DRL shape from the later 8Y generation
8Y (2020–present), standard trims	Standard Full LED — base-level LED lights with standard high/low beam functions but no camera-based adaptive functionality
8Y, S3/RS3 and higher trims	Matrix LED — genuinely different hardware using a front-facing camera and multiple individually controlled LEDs to shape the beam, keeping main beam on while creating dark spots around other vehicles; confirmed as not interchangeable with Standard LED units even within the same generation
Market note	Matrix LED headlights on North American-market cars are software-limited to basic high-beam functionality; full adaptive matrix behaviour is only enabled by default on European-spec cars, despite the hardware being identical
