ABS Speed Sensor – WHT 003 857 (HELLA)

Description

Product Description

The WHT003857 ABS Wheel Speed Sensor by Hella is an OE‑quality replacement used on various Volkswagen and Audi models. Mounted at the wheel hub, it continuously monitors individual wheel rotation and sends a precise signal to the ABS/ESP control unit so systems such as anti‑lock braking, traction control, and stability control can function correctly in all driving conditions.

Over time, the original sensor can suffer internal electrical failure, moisture intrusion, or damage to the wiring and connector. This often leads to ABS/ESP warning lights, disabled traction control, and cruise‑control issues. Replacing the faulty unit with this Hella WHT003857 sensor restores accurate wheel‑speed feedback and factory‑level operation of the vehicle’s braking and stability systems.
