BOSCH 0445110137 for Mercedes Vito / Sprinter OM646 CDI
A6460700187 A6460700287 A6470700187 A6470700087 F00VC01328 DLLA153P1246 1,600 bar peak Product Overview
The BOSCH 0445110137 is a complete injector assembly for Mercedes-Benz OM646 engine family - the second-generation CRI2 solenoid-actuated common rail fuel system used across the Vito (W639), Viano (W639), E-Class (W211), C-Class (W203/W204), and Sprinter (T1N). The F00VC01328 control valve operates via a precision solenoid with 3-6 micron clearance, regulating fuel flow for stable multi-pulse injection at up to 1350 bar peak rail pressure. The OE nozzle DLLA153P1246 (internal Bosch code 0433171788) is a multi-hole P-type nozzle delivering fine fuel atomisation for clean combustion. Compatible with OM646 (2.1L, 60-90 kW, Vito/Viano/W211) and OM647 (2.7L, 75-110 kW, Sprinter T1N) variants. Mercedes OE A6460700187 (also A6460700287 for sister 0445110139, A6470700187 for Sprinter 2.7L). Bosch aftermarket exchange 0986435113 (also 0986435109 / 0986435114 for sister SKUs).
Verify engine code OM646 on the block and OE number A6460700187 on the injector body before ordering. 0445110137 shares the F00VC01328 control-valve group with sister SKUs 0445110138, 0445110139, 0445110140, 0445110191, 0445110192, 0445110263, 0445110264 but each carries a unique IMA calibration code - NOT interchangeable without ECU re-coding.

Frequently Asked Questions
What P-codes does a faulty 0445110137 trigger on the OM646 / OM647 engine?
Common fault codes: P0201-P0204 (cylinder 1-4 injector circuit faults), P0300-P0304 (random misfire from worn valve or Black Death carbon buildup), and P0600-P0605 (ECU internal faults from voltage fluctuation). The OM646/OM647 is known for 'Black Death' - carbon buildup on the nozzle tip from short-distance cycles. This causes white smoke at idle and black smoke under load. Diagnosis: remove injector and inspect nozzle tip - if carbon is visible, replace as a set.
How do I confirm 0445110137 is the right part for my Mercedes Vito 115 CDI (W639)?
Verify: (1) Engine code - look for 'OM 646.982' stamped on the engine block; (2) OE part number - 0445110137 stamped on the injector body; (3) Connector - OM646/OM647 uses a 2-pin push-fit Deutsch connector. Cross-reference: A6460700187 = OM646 (2.1L Vito/Viano/E-Class); A6470700187 = OM647 (2.7L Sprinter T1N). Both use the same 0445110137 physical injector but different OE stampings.
0445110137 vs 0445110138 - what is the difference?
Both share F00VC01328 valve and nozzle 0433171788. 0445110137 = primary OE part; 0445110138 = alternative exchange number. Interchangeable mechanically - but the IMA code stamped on the solenoid body must match the ECU's expected value for that specific vehicle application.
What is the difference between OM646 and OM647 - can I use the wrong injector?
OM646 (2.1L, 60-90 kW) and OM647 (2.7L, 75-110 kW) use the same 0445110137 physical injector but different IMA calibration codes. OM647 (Sprinter T1N) operates at slightly higher rail pressure (~1350 bar vs ~1200 bar for OM646). Installing from one to the other may work mechanically but will cause fuel metering errors - the ECU will flag a fault until it learns the new injector.
What torque spec should I use for injector hold-down bolts on OM646 / OM647?
Mercedes-Benz procedure: (1) Apply thread sealant; (2) Pre-torque to 10 N·m (criss-cross); (3) Final torque to 25 N·m. WARNING OM646/OM647 uses TWO hold-down bolts per injector - tighten evenly to avoid tilting the injector body. Tilt > 0.5 mm contacts the piston and cracks the ceramic tip.
Does the 0445110137 require ECU coding after installation on the Vito / Sprinter?
Yes - mandatory on all OM646/OM647 engines. Use Star Diagnostic (SDS), HHT, or Autel with DAS/Xentry. Navigate to Motor Electronics -> Injection -> Code Cylinders -> enter the 4-digit IMA code from the new injector label. Without coding, the ECU stores P0300 for 10-15 minutes. Workshop time: 45-90 minutes including road test.
What is the warranty on 0445110137 and what voids it?
Standard warranty: 12 months from invoice date. Covers: solenoid open-circuit, control valve seizure, nozzle blockage. Voided by: (1) cracked nozzle tip from tilted insertion; (2) Black Death carbon damage; (3) fuel contamination; (4) missing ECU coding; (5) bio-diesel above B7. Keep Star Diagnostic coding report as warranty evidence.
0445110137 vs 0445110140 - are they interchangeable?
No - 0445110140 is for the OM648 engine family (3.0L, W211 E320 CDI post-2005), which uses a different injector design with updated solenoid and different rail pressure. 0445110137 is NOT interchangeable with OM648 injectors. Verify engine code on the block.
What is 'Black Death' on OM646/OM647 and how does it affect injector selection?
Black Death is carbon buildup on the injector nozzle tip from repeated short journeys that never fully heat the combustion chamber. Symptoms: white smoke at cold idle, black smoke under load, then P0300. Prevention: occasional 30+ minute motorway runs. If Black Death is present, replace all 4 injectors as a set - individual replacement won't resolve the issue. 0445110137 will restore proper spray pattern if the engine is otherwise healthy.
