Persistent Squealing Brakes on my 2022 Audi Q5

Vehicle: 2022 Audi Q5 Premium Plus

Hey everyone,

I've got a 2022 Audi Q5 Premium Plus with about 15,000 miles on it, and I'm experiencing some really annoying brake squeal. It's most noticeable at low speeds, like when I'm coming to a stop sign or creeping in traffic. It's not a constant high-pitched squeal, more like a periodic groan/squeal.

I've tried bedding the brakes a few times, but it doesn't seem to make a lasting difference. The car brakes fine otherwise, no pulsing or loss of stopping power. Is this just a characteristic of Audi brakes, or should I be concerned? Any ideas on what might be causing it and what I can do?

Thanks for any help!

ClearTheCode admin answer:

Persistent brake squeal on a relatively new vehicle like your 2022 Audi Q5 Premium Plus can be frustrating. While some brake noise can be normal, especially with performance pads, constant squealing often indicates a specific issue.

Here are common causes and steps to consider:

  1. Brake Pad Material: Some OEM or aftermarket brake pads are formulated for performance and can be prone to squealing, especially when cold or at low speeds. Harder metallic pads can be noisier than ceramic ones.
  2. Rotor Glazing/Wear: Over time, rotors can develop a glazed surface or uneven wear patterns that contribute to noise. Even new rotors can sometimes have minor imperfections.
  3. Brake Pad Wear Indicators: While your vehicle is relatively new, it's worth checking the brake pad wear sensors. If a sensor is faulty or nearing activation, it could cause a squeal, though typically this triggers a dashboard warning light (no OBD code for simple squeal, but a wear sensor fault might show up as C1100).
  4. Improper Installation/Lubrication: If the pads or rotors were recently replaced, improper lubrication of caliper pins or anti-squeal shims could be the culprit. Dust and debris can also get trapped.
  5. Caliper Issues: Less common on a new car, but a sticking caliper piston or guide pin could cause uneven pad wear and noise.

When to See a Shop:

  • If the squealing is accompanied by grinding, pulsing, or a noticeable change in braking performance.
  • If you notice any dashboard warning lights related to the braking system (e.g., ABS, brake wear). If an OBD scan shows a code like C1100 (Brake Pad Wear Sensor), it's definitely time for a professional inspection.
  • If the noise persists despite attempts to re-bed the brakes or if you're uncomfortable inspecting the components yourself. A technician can properly diagnose the source, check pad thickness, rotor condition, and caliper function, and recommend appropriate solutions like cleaning, resurfacing rotors, or replacing pads with a different compound.
