OEM Part Number: confirm via VIN — aftermarket LH Hella 1EL 011 150-351 / RH Hella 1EL 011 150-361

Accuracy note: Covers the Audi A6 (C7 2011-2018) as listed in the UK aftermarket catalogues. Headlights are sold by side (passenger / nearside = LH, driver's / offside = RH on a UK car) and by lamp type — halogen, xenon (D1S / D3S) and LED or full-LED units are not interchangeable, and DRL, cornering and levelling options change the part number again. The references below are UK aftermarket catalogue listings for this generation, labelled by brand; genuine numbers are shown only where a listing quotes one. Check the lamp type and traffic side (UK right-hand-traffic units, not LHD) against your VIN, and expect xenon / LED and adaptive units to need levelling adjustment or coding after fitting.

Passenger side (LH / nearside) headlight — aftermarket	TYC 20-12880-06-2 (xenon D3S/H7 with LED, DRL, electric); Hella 1EL 011 150-351 (bi-xenon D3S/H7, LED DRL, motor); Hella 1LL 011 150-371 (bi-xenon, LED DRL, motor); Van Wezel 0342983 (xenon D3S/H7, LED DRL, motor); Prasco AD0384914 (halogen H15/H7, DRL, motor); Hella 1EX 012 976-111 (full LED)

A Genuinely Important UK Rule Worth Knowing Before You Buy — Audi A6 Headlights

If your A6 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 A6 Headlights: What It Does

Precise beam angling to light the road without dazzling oncoming traffic is the Audi A6's headlight unit's core job, housing the main and dipped beams — or LED/matrix modules on higher trims. Because it often also integrates the daytime running light and front indicator, both the part number and repair complexity increase accordingly.

Audi A6 Headlights: Generations & Headlight Type

C5 (1997–2004)	Halogen or single-Xenon depending on trim, both using projectors now known to have documented reflective-layer degradation with age, causing dangerously low light output on unrestored examples
Current generation	LED standard, with Matrix LED and HD Matrix LED (using digital micromirror technology) offered as higher options
