New Pair Rear Liftgate Position Sensor for Mercedes X164 GL320 GL350 GL450 GL550

Rear Liftgate Position Sensor Pair for Mercedes X164

This pair of rear liftgate position sensors replaces the units that signal the power liftgate on Mercedes X164 GL320, GL350, GL450, and GL550 models.

Overview

These rear liftgate position sensors report the open and closed position of the power liftgate so the system knows when to stop, reverse, or latch. Sold as a pair, they replace worn or failed sensors on the X164 GL-Class and restore proper liftgate operation. This set is for X164 owners dealing with a liftgate that stalls, reverses, or refuses to move.

Specs At A Glance

Good To Know

Q: Do I need to replace both liftgate position sensors at the same time? A: Replacing them as a pair helps keep the liftgate feedback balanced and avoids a second repair soon after. This listing already includes both sensors.

Q: Will a faulty position sensor stop the power liftgate from working? A: Yes, a failed sensor can cause the liftgate to stall, reverse, or ignore the open command. Replacing the sensors is a common fix for those symptoms.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
