Parts for your 2013 Audi Q5-Brake pad wear indicator

2013 Audi Q5 Brake Pad Wear Indicator

Based on Audi’s own technical literature and parts data, the brake pad wear indicator is fitted to the 2013 Audi Q5 (type 8R). The 2013 Q5 Owner’s Manual describes a brake pad warning in the instrument cluster, the Audi ELSA workshop manual (Brakes, section 46—Electrical wear indicator) details the circuit and testing method, and the ETKA parts catalogue lists the wear indicator lead on the front axle for 8R models, with some variants also carrying a rear sensor depending on PR-codes. So it’s relevant and actively used on this model.

On the Q5, the brake pad wear indicator is a small electrical sensor embedded in the brake pad material. As the pad wears down with kilometres, the sensor eventually contacts the disc or opens the circuit, triggering a “Brake pads” warning on the dash. It’s a clever bit of kit that helps prevent running pads too thin, protecting discs, keeping stopping distances short, and avoiding that dreaded metal-on-metal grind.

As part of routine servicing, the indicator is treated as a consumable—once it’s tripped, it’s generally replaced along with the pads. The front left pad set typically carries the sensor on 2013 Q5 models, some builds include a rear sensor as well. After new pads and a fresh sensor lead are installed and correctly connected, the warning light clears by itself—no special reset is normally required. If the light stays on, the workshop will check the harness routing, connector fitment, and scan for faults with a suitable tool.

Good practice on a Q5 service includes:

• Inspecting pad thickness and the sensor lead for abrasion or heat damage.
• Replacing the wear sensor whenever fitting new pads, it’s inexpensive insurance.
• Routing the lead in the factory clips to keep it away from the wheel and suspension.
• Checking the rear axle: some variants have a sensor, others rely on pad inspection only.

Because the Q5 runs an electronic parking brake at the rear, rear pad servicing uses a service mode via scan tool to retract the motors before pad replacement. That’s separate to the wear indicator, but it’s worth noting when planning brake work at a service centre.

Looked after properly, the indicator helps the 2013 Audi Q5 deliver confident braking, smooth pedal feel, and reduced disc wear—all without guesswork about pad life.

Does the 2013 Audi Q5 actually have a brake pad wear sensor?

Yes. Audi documentation for the 8R Q5 shows an electrical wear indicator on the front axle, and some variants also have one on the rear. The exact fitment can be confirmed by the vehicle’s PR-codes on the build sticker or via a parts lookup.

How is the brake pad warning light reset on a 2013 Q5?

There’s no manual reset. Once new pads and a new wear sensor are installed and plugged in correctly, the warning clears automatically. If it doesn’t, a technician will check the wiring and run a fault scan to rule out a broken lead or connector issue.

Should the wear sensor be replaced every time pads are changed?

Best practice is yes. The sensor is a sacrificial part and can be heat-cycled or partially worn. Given the low cost, replacing it with the pads helps avoid nuisance warnings and keeps the system reliable.
