Detailed Description

Carlson 19156 is a front disc brake pad wear sensor built for Audi models that use an electronic pad wear indicator. It serves as the sensor interface for the brake warning system, helping the driver identify when front brake pads have reached the wear limit. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Vehicle coverage includes 2016-2018 Audi A6, 2016-2018 Audi A6 Quattro, and 2015-2018 Audi A7 Quattro, all in the front position.

What It Helps Address

• Brake pad wear warning light staying on after pad service
• Damaged or worn front pad wear sensor wiring
• Incorrect wear sensor readings from a failed sensor
• Brake service on Audi A6, Audi A6 Quattro, or Audi A7 Quattro front brakes

Installation Notes and Tips

Verify the original sensor routing and connector style before installation. Inspect the brake pad wear circuit, connector terminals, and nearby harness for damage during brake service. Confirm front-position fitment for the specific vehicle before ordering, and replace the sensor when the brake pad wear indicator system requires service.
