What It Helps Fix

• Broken or brittle ABS sensor connector housings
• Corroded or overheated wheel speed sensor terminals
• Intermittent ABS warning lights caused by poor electrical contact
• Damaged harness ends at the wheel speed sensor connection
• Signal loss from worn brake electrical connector interfaces

Installation Notes and Tips

• Verify connector shape, terminal style, and harness length before installation.
• Match the vehicle position exactly as listed in the fitment data, including front left, front right, rear, front, or N/A entries.
• Inspect the sensor pigtail and surrounding wiring for heat, abrasion, or corrosion before connecting the new part.
• Confirm terminal engagement and locking fit after installation to help maintain a stable ABS signal.
• For fitment-specific service, reference the vehicle year, make, model, and position shown for S3138.

Quality Assurance

Standard Ignition is a recognized name in replacement electrical components, and S3138 is built to match the connector style and service requirements called out in the fitment and attribute data for Audi brake sensor repairs.
