Parts for your 2016 Audi Q5-Tail lights

2016 Audi Q5 tail-lights — purpose, care and when to replace

Tail-lights are absolutely fitted and relevant on the 2016 Audi Q5 (Type 8R). Technical sources including the 2016 Audi Q5 Owner’s Manual, Audi Genuine Parts Catalogue (ETKA, Group 94), and lighting regulations such as Australian Design Rule ADR 13/00 and UNECE Regulation No. 7 (adopted in NZ under the Land Transport Rule: Vehicle Lighting 2004) all specify rear position lamps (tail-lights) as mandatory equipment on this model.

On a 2016 Q5, the tail-lights are there to keep the vehicle visible from behind in low light and at night, and to signal braking and direction changes when combined with stop and indicator functions. Depending on trim and market, the Q5 may use conventional bulbs or LED modules in the rear lamps. Either way, properly working tail-lights are essential for safety, compliance, and passing a WOF or roadworthy check.

As part of routine servicing, it’s smart to check the tail-lights every few months or before long trips. A quick walk-around with the lights on (and someone pressing the brake pedal) will pick up most faults. Keep the lenses clean so the red colour and light output aren’t dulled by road grime.

• Common signs of trouble: bulb-out warning on the dash, dim or flickering lamps, moisture or fogging inside the lens, cracked housings, or mismatched brightness left-to-right.
• For bulb-equipped lamps: replace like-for-like wattage and base type recommended in the Owner’s Manual. Avoid touching glass bulbs with bare fingers. Check connectors for corrosion and the earth point for a solid connection.
• For LED-equipped lamps: individual diode failures usually mean replacing the lamp assembly or LED module. Some replacements may need coding with a diagnostic tool so the bulb monitoring system is happy.

If the lamp fills with condensation or the lens is cracked, moisture can damage electronics and reduce visibility. Resealing can be a short-term fix, but replacing the housing is the reliable, compliant option. After any rear knock or bumper repair, confirm the lamp alignment and that the seals are intact.

When towing, a faulty trailer plug or module can trigger warnings or odd light behaviour. Test with the trailer unplugged, if the warning clears, check the trailer wiring. Always use quality parts — genuine or reputable aftermarket — and match the vehicle’s spec by VIN to avoid fitment or coding hassles.

What bulbs does a 2016 Audi Q5 use for the tail-lights?

It depends on the exact build. Some 2016 Q5s run conventional bulbs, while many have LED tail-lights. For bulb-type lamps, the rear position/stop functions commonly use dual‑filament bulbs of the specified wattage for the model year, reverse and indicators use dedicated types. The safest approach is to check the Owner’s Manual or confirm by VIN to ensure the correct parts.

Why is there a tail-light warning on the dash?

The car’s bulb monitoring has detected a fault — typically a blown bulb, failing LED module, poor connector contact, or an earth issue. Towing gear with wiring faults can also trigger it. Inspect the relevant lamp, check fuses and connectors, and replace the bulb or lamp assembly as required. LED replacements may need coding so the warning clears.

Can a cracked tail-light be repaired or should it be replaced?

A minor crack might be temporarily sealed to keep water out, but it’s best practice to replace the lamp assembly. Moisture leads to fogging, corrosion, and reduced light output, which can cause a failed WOF/RWC. A new, properly sealed unit restores performance and compliance.
