Automatic deactivation of Start & Stop on Mercedes CLA C118
On the Mercedes CLA, the Stop & Start system can quickly become annoying: untimely engine cut-offs in urban traffic, less smooth acceleration, vibrations felt on automatic versions… These interruptions impair premium comfort and the responsiveness of petrol and diesel engines.
➡ Thanks to our Plug & Play electronic module, the Start & Stop function is automatically deactivated at each start-up.
No manipulation is necessary: you start it, the engine continues to run smoothly and naturally.
Do you want to revert to the original configuration?
➡ Simply unplug the module. No coding or technical intervention required: 100% reversible installation.
Free delivery – 1-year manufacturer's warranty
Why equip your Mercedes CLA C118 with this module?
The Start & Stop system often presents more disadvantages than advantages in everyday use:
- Increased strain on the starter and battery.
- Cut-offs before optimal turbo lubrication.
- Jerky restarts.
- Reduced responsiveness in overtaking and quick insertions.
- Unexpected cuts during maneuvers or on slopes.
➡ This module significantly improves driving comfort and the mechanical longevity of your vehicle.
