The main advantages of this solution include:

• consistency with the vehicle's factory electrical architecture,
• preservation of the original pedal operating characteristics,
• no need for installation modifications or additional mechanical adaptations.

Component condition and installation aspects

The offered gas pedal is a secondary market component, which allows for economical vehicle repair while maintaining the original Mercedes construction. This type of component is intended for installation in place of the factory pedal, using existing mounting points and electrical connectors, in accordance with the manufacturer's service procedures.

Before installation, it is recommended to:

• verify compatibility by OEM number or vehicle VIN,
