ABS Light Stuck On in Your Mercedes GLE V167? Here's What to Check

Why your GLE V167's ABS light stays on

On a Mercedes-Benz GLE V167, a continuously lit ABS warning light (not flashing) usually means the ABS/ESP control module has stored a fault and disabled the system. The most common cause is a wheel speed sensor signal problem, but other faults can produce the same symptom. Wiring damage, a corroded connector, a damaged tone ring (encoder ring), low battery voltage, or a failing ABS control module can all trigger the same light. Because the system shares data with traction control, stability control, and hill assist, you may also see a message like 'ESP unavailable' or 'See Owner's Manual'. Don't assume the sensor is bad until you test it.

What to check first — and what's usually replaceable

• Scan for fault codes and live wheel speed data. Use a Mercedes-capable scan tool to read the ABS/ESP module. A code for a specific wheel speed sensor is a starting point, but live data while driving or spinning each wheel can show an intermittent dropout. This step often prevents unnecessary parts swapping.
• Wheel speed sensor and wiring. On most V167s, the wheel speed sensor is a separate bolt-in part at each wheel, not part of the hub. Inspect the sensor tip for metal debris, check the connector for corrosion or pushed pins, and look for chafed wires near the suspension. Replacing just the sensor is usually sufficient if it has failed; repairing a damaged wire is often enough when the sensor itself tests fine.
• Tone ring / encoder ring. Some GLEs use a magnetic encoder ring that the sensor reads. If that ring is cracked, contaminated, or missing teeth, you'll get a wheel speed fault even with a new sensor. On some versions the ring is a separate seal that can be replaced on its own; on others it's part of the wheel bearing or hub assembly. Confirm the exact setup for your model year and VIN before ordering parts — a full hub replacement is a fallback, not the default.
• ABS control module, power, and grounds. Less common, but possible. Check battery voltage and charging system first, since low voltage can set false ABS codes. Inspect fuses and ground points. If the module itself is faulty, some units can be rebuilt or reprogrammed; full replacement is usually a last resort after sensor and wiring faults are ruled out.

Is it safe to keep driving?

If the ABS light is on but the brake pedal feels normal, there are no other brake warnings, and the vehicle stops straight, you can usually drive cautiously to a repair shop. Just remember that ABS and stability control may be disabled, so braking distances can be longer in wet, icy, or emergency stops — drive accordingly. If you also see a red brake warning light, feel pulsation or pulling, hear grinding, or get multiple chassis warnings, stop safely and have the car towed. A steady ABS light is not an emergency by itself, but it's a sign to get a proper diagnosis soon rather than ignore it for weeks.
