Rarely Used, Easy to Forget About Until Needed
The Audi A5 Coupe's fog lights sit unused for most owners most of the year, which means a fault can go unnoticed for a long time — right up until a genuinely foggy morning makes the problem obvious at the worst possible moment.

Not every A5 Coupe trim comes with front fog lights — some use a styled blanking cover in the same bumper location instead, and S Line/S5/RS5 bumpers use a different opening design to standard Sport trim. Confirm your exact trim before assuming this part applies to your car.
Audi A5 Coupe Fog Lights: What It Does
Front fog lights are angled and positioned to illuminate the road surface in low visibility conditions without creating the glare a standard headlight beam would in fog. Some higher trims of the A5 Coupe integrate fog lights into the same housing as cornering lights or daytime running lights, which affects both the part number and the complexity of any repair.

Fitment & Compatibility
Audi A5 Coupe Fog Lights: Generations, Derivatives & Fog Light Type
| Standard trims, halogen headlight cars | Front fog lights are conventional halogen units, and genuinely double as static cornering lights on cars without HID/adaptive headlights — this cornering function is coding-enabled rather than always active from the factory |
|---|---|
| R-Line/higher trims, LED headlight cars | Genuine LED fog lights become available, with cornering function built into the main headlight unit instead of the fog light on cars with the full adaptive lighting package |
Not every trim level of the A5 Coupe comes with fog lights fitted as standard, and the housing design often differs between trims that have them integrated with other lighting functions and those with a standalone unit. Always confirm your specific trim's fitment before ordering. Whether you're sourcing a replacement fog 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 Multiple Light Failures — Audi A5 Coupe Fog Lights
If multiple lights fail together, this is genuinely worth knowing: documented cases on related Audi models describe several lights failing around the same time being traced to a genuinely faulty fuse box, with individual fuses found melted inside it.
It's also genuinely worth knowing that a complete lack of power to the front fog lights has, in documented cases, simply been down to dirty contacts or a relay not fully seated, rather than a genuine component failure.
