The Mercedes-Benz OM646 is a 2.1L inline-4 CDI (common rail diesel injection) engine powering some of Mercedes-Benz's most popular passenger and commercial vehicles — the E-Class E320 CDI, Viano MPV, and Vito van. The Bosch CRI2.1 high-pressure common rail system operates at up to 1600 BAR, delivering precise fuel atomization for smooth power delivery, low emissions, and excellent fuel economy. When an injector fails, you'll experience rough idle, misfires, hard starts, power loss, increased fuel consumption, and black smoke. This brand-new aftermarket Bosch CRI2.1 injector is a direct replacement covering 9 cross-reference formats across Bosch and Mercedes-Benz OEM part numbers, including Bosch 0445110193 and Mercedes OEM 6480700387 / A6480700387.
