Product Details

This MPA Electrical starter is built for direct replacement use on select Mercedes-Benz applications, including 2012-2015 Mercedes-Benz C250, 2012-2015 Mercedes-Benz SLK250, and 2003-2005 Mercedes-Benz C230. The permanent magnet gear reduction layout helps deliver compact packaging with the electrical and mechanical specifications needed for these vehicles. If you are replacing a worn starter on a Mercedes-Benz C250, SLK250, or C230, part number 17920N provides the correct 12-volt, clockwise, 9-tooth configuration.

MPA Electrical’s New line identifies this as a new replacement starter for service work where the original unit has failed or no longer cranks consistently. This part cross-references Bosch (e.g., 17920N) for the same application.

What It Helps Fix

• No-crank condition when the key is turned
• Slow or weak engine cranking
• Intermittent starter engagement
• Starter noise from worn internal components
• Starting issues caused by a failing starter motor

Installation Notes and Tips

Verify the vehicle’s year, model, and starter specifications before installation. Confirm 12-volt system requirements, clockwise rotation, and 9-tooth drive count against the removed unit or service information. Check battery condition, cable integrity, and charging system output during diagnosis so the new starter is not installed over an unresolved electrical fault.

Quality Assurance

MPA Electrical 17920N is a new starter built to the listed Bosch-based specifications for the confirmed Mercedes-Benz applications. Use the part number 17920N and the vehicle fitment details to confirm the correct replacement before installation.
