Audi Q5 Fog Lights: Rarely Used, Easy to Forget About Until Needed
The Audi Q5's fog lights sit idle for the vast majority of owners most of the year, which is exactly why a fault can go undetected for months — surfacing only on the one properly foggy morning when it matters most.
Audi Q5 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 Q5 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 Q5 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 Q5 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 Q5 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 Q5 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.
