KM/Mile Freezer for the Mercedes GLA Class X156

Description

Overview

Our Mercedes GLA Class X156 mileage blocker is a dedicated plug-in module designed for the Mercedes GLA Class X156. It temporarily stops mileage (or kilometres) from being recorded while the vehicle is in motion, and is intended only for off-road use, dyno testing, and vehicle development or tuning.

Compatibility

This mileage blocker is compatible with:

• Mercedes GLA Class X156
• For vehicles with the display as shown in the product images

If you are unsure whether your vehicle is compatible, please contact us with your VIN and a photo of your dashboard before ordering.

Key features

• True plug-and-play installation – fits directly behind the cluster, with no cutting or soldering required.
• OEM-style connectors – supplied with original-type plug connections for a secure, factory-style fit.
• Control at the touch of a button – activate or deactivate the module with a button press, even while driving.
• Designed for stable integration when correctly installed.
• Memory of last setting – the module remembers whether it was on or off when the vehicle was last used.
• Full functionality retained – the speedometer and driver assistance systems continue to operate normally.

How the mileage blocker works

The module connects inline with the vehicle’s instrument-cluster wiring using the supplied plug-and-play harness for authorised off-road, dyno and vehicle-development testing. When returned to normal operation, the vehicle behaves as standard.
