More Wiring Behind There Than Most People Assume
The Audi A5 Coupe's tail lights pack brake, indicator, reversing and rear fog functions into a single unit, so a fault in the wiring or housing can affect several of them simultaneously — meaning "the tail light's broken" could describe quite different underlying problems.
Audi A5 Coupe Tail Lights: OEM Part Number
The 2019 facelift revised the A5 Coupe's tail light design and internal LED graphics, meaning pre-facelift (2016–2019) and post-facelift (2019–2024) cars use genuinely different, non-interchangeable units. Confirm which side of the facelift your car falls on before ordering.
Audi A5 Coupe Tail Lights: What It Does
Beyond basic rear visibility, tail light units on the A5 Coupe typically integrate brake lights, indicators, reversing lights and rear fog lights into a single housing. Higher trims may use LED units with a distinct light signature, which are not interchangeable with standard halogen units even if the physical mounting looks similar.
Fitment & Compatibility
Audi A5 Coupe Tail Lights: Generations, Derivatives & Tail Light Type
| Standard trims | LED tail lights with dynamic turn signals and animation are standard on current generations, with halogen fitted to older models |
|---|---|
| Q5 only (within this generation family) | Genuine digital OLED tail lights are offered as an option exclusively on the Q5 — confirmed as NOT available on the closely related A4 or A5, despite sharing the same underlying platform |
Tail light design changed between generations of the A5 Coupe, and facelifted versions within the same generation often use a revised light signature that isn't interchangeable with pre-facelift units. Always confirm the exact part for your specific model year before ordering. Whether you're sourcing a replacement tail lights for your Audi A5 Coupe from a dealer, specialist, or online marketplace, always check compatibility against your registration or VIN before buying, and confirm you're ordering the correct side — driver's side (RH in the UK) or passenger side (LH in the UK) — since these are not interchangeable.

A Genuinely Useful Piece of Context Worth Knowing About Tail Light Condensation — Audi A5 Coupe Tail Lights
If a dealer suggests condensation in a tail light is simply normal, this is genuinely worth knowing: documented cases on related Audi models describe owners comparing otherwise identical cars, finding some show condensation while others genuinely don't — worth pushing for a proper repair rather than accepting a blanket explanation.
It's also genuinely worth knowing two distinct causes worth checking separately: the rubber seal running centred around the cluster, and separately the cluster itself for hairline cracks — and that the light unit can, in at least one documented case, physically separate at a seam over time.
