Automatic Start/Stop Deactivation for Mercedes B-Class W247 (2019–2025)
Plug-and-play electronic module designed to disable the Start/Stop function every time the vehicle is started, without coding or vehicle modification. The device installs between the original connector and the Start/Stop button, preserves the original look of the interior, and is completely reversible.
Operation and Benefits
The module keeps the engine running continuously after starting to eliminate the untimely stops and restarts caused by the Start/Stop system. Result: smoother city driving, reduced micro-jerks during restarts, and a better driving experience with automatic transmissions. This device limits the perceived strain on the transmission during repeated engine cut-outs.
Installation and Compatibility
Direct connection to the Start/Stop button socket, average installation time: approximately 15 minutes. No specialized tools or reprogramming required, fully reversible installation. Compatible with Mercedes B-Class W247 (2019 to 2025), including AMG variants, provided the vehicle is equipped with the original Start/Stop button.
