Product Details

MPA Electrical 12139 is a remanufactured starter intended for vehicles that require a Bosch-style, clockwise-rotation unit with a flange mount and 9-tooth engagement. The remanufacturing process is performed in TS16949 certified facilities, supporting consistent dimensional accuracy and repeatable electrical performance. This makes it a strong match for repair work where the original starter has worn brushes, weak cranking output, or intermittent engagement.

This starter is relevant for Bosch starter applications across select makes and models, including vehicle searches for BMW starter replacement and Mercedes-Benz starter replacement where the original equipment specification matches these attributes. If you are cross-shopping by part number, 12139 is the reference to verify against the original unit before installation.

This part cross-references Bosch-style starter numbers such as D6RA8 and D6RA16 for the same application.

Common Starting Issues It May Address

• Engine cranks slowly or inconsistently
• No-crank condition with a functioning battery
• Starter engagement noise from worn drive components
• Intermittent starting after heat soak or repeated starts
• Electrical wear in an aging original starter assembly

Installation Notes and Tips

Confirm voltage, rotation, tooth count, mounting style, and Bosch family match the original starter before installation. Compare the old unit to Part Number 12139 and verify connector and mounting alignment on the vehicle. Clean battery terminals, inspect cables, and check charging-system condition so the replacement starter is not affected by upstream electrical faults.

For fitment-based searches, verify the exact application by year, make, model, and starter configuration before ordering. This is especially important on BMW and Mercedes-Benz starter replacement jobs where multiple starter variants may exist within the same platform.
