Relaunched in 2009 after an absence of several years, the Mercedes E-Class incorporated Start-Stop technology in many of the models across the range, particularly in the eco-friendly Blue EFFICIENCY versions.
As many examples are well within reach of the independent sector, workshops and the technicians undertaking service and repair work on these variants, need to bear in mind that all post-2009 E-Class models are designed to use high performance batteries such as the VARTA® Silver Dynamic AGM. In addition, those with a Start-Stop system will also require specialist knowledge and equipment to ensure the correct removal and installation process is followed.
As the battery in the Start-Stop system is integrated with the vehicle’s battery management system and its ECU, thorough diagnosis is required to discover whether the battery needs to be replaced or if there is an underlying cause that might have led to its premature failure.
Having the ability to cancel and reset the fault codes that may be required for associated components like the alternator and starter motor, as well as the Start-Stop system, means that workshops would be wise to invest in the necessary tooling and training to allow them to tackle these issues.
