Under its Lemförder brand, ZF Aftermarket has introduced a range of switchable engine mounts for a number of Audi and Mercedes Benz models. Using an integrated air spring this can actuate two different characteristic curves depending on vehicle and rotational speed. The mounts are currently available for Audi and Mercedes-Benz vehicle models and includes the Audi A4, A5, A6, Q5, Q7 and Mercedes C and E Class, GLK, GLC. ZF Aftermarket recommends that all engine mounts always be replaced during repairs, not just the defective part. Otherwise, there is a risk that the new component will have to absorb higher forces and vibrations because the remaining mounts are already heavily worn which may accelerate subsequent damage.
