    Is there a problem with the 48-V MHEV system in your Audi, BMW, Land Rover, or Ford? In many cases, the cause is damage to the DC/DC converter—a key component of the entire 48-V system.

    Most service centers offer an expensive replacement with a new unit. We offer an alternative: component-level repair of the DC/DC converter using our proprietary technologies and specialized diagnostic test benches.

    Why is this a good deal?

    • Repair instead of replacement—we fix the root cause of the malfunction and return the original unit to you at a significantly lower price
    • Specializing in 48 V MHEVs—we repair starter-generators, DC/DC converters, and 48 V batteries
    • In-house MSG Equipment diagnostic test benches—we perform load testing, not just reading error codes
    • Parts from Europe and the U.S.—hard-to-find electronic components are always in stock
    • Full service cycle under one roof: diagnostics → disassembly → electronics repair → testing → reassembly → test drive
    • We accept dismantled units from all over Europe
