Parts for your 2020 Audi Q5-Brake pad wear indicator

2020 Audi Q5 Brake Pad Wear Indicator

Yes — the 2020 Audi Q5 (type 80A/FY) is fitted with electronic brake pad wear indicators. The Audi Q5 Owner’s Manual for this generation shows the yellow “Brake pads” warning in the instrument cluster and explains the alert when the pads approach the service limit. Audi’s workshop documentation (ErWin) details pad replacement procedures “for vehicles with brake pad wear sensor,” and the Audi Genuine Parts catalogue (ETKA) lists dedicated pad-wear sensor leads for the Q5 FY on the front axle and, depending on build and market, the rear axle as well. These technical sources confirm the vehicle uses an electronic wear-indicator system.

On the 2020 Q5, the brake pad wear indicator is a simple, smart safeguard. A small sensor wire is embedded in the pad’s friction material. As the pad wears down through normal driving, the sensor circuit eventually contacts the disc or opens, triggering a dashboard warning. That early heads-up helps the driver book a pad change before braking performance tails off or the disc gets damaged. Some pads may also include an acoustic “squealer” as a backup, but the Q5’s electronic alert is the main cue.

When servicing brakes on a 2020 Q5, it’s good practice to replace any sensor that has triggered a warning, along with the pads. Once a sensor has worn through, it’s effectively a single-use item. Even if it hasn’t tripped yet, many technicians opt to renew the sensor during a pad change to avoid nuisance warnings down the track.

Care matters when fitting the new lead. Route the cable exactly as the factory did, clipped away from the wheel, strut and driveshaft, and keep it clear of ABS wiring and the tyre. If the rear pads are being changed, remember the Q5’s electronic parking brake needs to be placed into service mode with a scan tool before retracting the rear calipers. After the job, the brake-pad warning will usually clear on its own once the ignition is cycled, if a message lingers, a quick scan and clear of stored faults may be required.

As part of routine servicing, a visual check of pad thickness and sensor lead condition is worthwhile. Look for cracked insulation, loose clips, or chafing. If one axle has triggered a warning, have the other axle measured too — wear can be uneven based on driving style and loads.

• Replace triggered sensors with the new pads.
• Follow factory routing and clip positions for the sensor lead.
• Use service mode for the rear EPB before pad work.
• Verify the warning clears and perform a short, careful bed-in drive.

FAQs

How does the brake pad wear indicator work on a 2020 Audi Q5?
It’s an electrical loop moulded into the pad. When the friction material wears to a set point, the loop breaks or contacts the disc and the car displays a “Brake pads” warning in the cluster. It’s designed to warn with enough pad left to plan a change, not to signal an emergency stop.

Do the wear sensors need replacing every time the pads are changed?
If a sensor has triggered, replace it with the pads — it’s a one-time item. If it hasn’t triggered and is physically perfect, some workshops will reuse it, but most prefer to fit a new sensor to avoid intermittent warnings and to keep the system as reliable as possible.

Will the warning light reset itself after new pads and sensors are fitted?
Often yes — once the circuit is restored and the ignition is cycled, the warning disappears. If it stays on, check the sensor routing and connections, then clear any stored faults with a scan tool. A short test drive with a few gentle brake applications helps confirm everything’s sweet.
