VAG 2-Pin Brake Pad Wear Sensor Plug (1J0 973 802, Male): Quick, Clean Repair That Lasts

Pad wear sensor connectors sit in a harsh wheel-arch environment. Broken clips and corroded pins throw false pad warnings. Replace the plug and terminals for a long-term fix.

Typical Faults

• Warning light stays on even with new pads
• Plug doesn’t lock; clip is cracked or missing
• Green/white corrosion at the pins from water and road salt

Repair Steps

1. Unclip the old connector; cut back to clean copper.
2. Crimp new terminals (no solder), insert until the primary lock engages.
3. Seat the secondary lock and verify a positive click on the mating part.

Tech Check

Measure continuity across the sensor loop after repair; intermittent readings indicate a seating or crimp issue.
