Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Controllable engine mounts
The engine has engine mounts that can be enabled, familiar from vehicles with diesel engines. The engine mounts that can be enabled are set by means of partial vacuum to hard or soft to ensure a comfortable start and idling of the combustion engine. As soon as the partial vacuum is no longer applied to the engine mounts, they are switched to hard. The electric changeover valve of the controllable engine mounts is activated by the Digital Engine Electronics (DME).
