This part cross-references Centric Parts 116.37044 for the same application. It also cross-references Raybestos Brakes EWS242 for the same application. Search terms such as Porsche Macan front brake wear sensor, front electronic brake pad sensor for Porsche Macan, and SW-1546 replacement sensor apply to this part.

What It Helps Address

• Brake wear warning light triggered by a worn front sensor
• Damaged or brittle sensor wiring during brake pad replacement
• Loss of pad wear monitoring after front brake service
• Incorrect sensor fitment from non-OE-style replacements
• Front brake maintenance on Porsche Macan models with wear-indicator systems

Installation Notes and Tips

Install SW-1546 on the front axle only for the listed Porsche Macan applications. Verify connector shape, terminal style, and harness routing before installation, and inspect the sensor path for heat damage or abrasion. Replace the sensor when servicing worn front pads so the brake wear indicator system can reset and operate correctly.
