Bosch 0445110034 CRI Injector – The Mercedes-Benz OM611 Diesel’s Silent Partner

In the Bosch 0445110 series, some numbers are famous. Others are simply essential. The 0445110034 belongs to the second category - a common rail injector that doesn't seek attention but delivers precision with every pulse, mile after mile, across some of the most demanding light-duty diesel applications ever built.

This is a CRI (Common Rail Injector) from Bosch's solenoid-actuated injector family - the technology that helped Mercedes-Benz redefine diesel refinement in the early 2000s. If you've driven a Sprinter van across Europe, a V-Class through the Alps, or a Vito around city streets, you've likely experienced the 0445110034 at work - metering fuel with Bosch's characteristic precision, cylinder after cylinder, without drama or complaint.

 

 

The 0445110034 belongs to Bosch's CRI (Common Rail Injector) family - a generation of solenoid-actuated injectors that represented a significant leap forward in diesel injection technology when they first appeared.

What makes the CRI architecture different:

Solenoid-actuated - an electromagnetic actuator controls the opening and closing of the injector needle, allowing for precise control over injection timing and duration

Hydraulic servo system - uses fuel pressure to amplify the solenoid's force, enabling rapid needle opening even at rail pressures exceeding 1,600 bar

Compact design - the injector's slim profile allows it to fit within the cylinder head's cooled area, protecting heat-sensitive components from thermal stress

What this means in practice:

Precise fuel metering - the ECU controls injection timing and duration with millisecond accuracy

Clean combustion - precise control over the injection event reduces NOx and particulate formation

Improved fuel economy - every drop of fuel is used efficiently

 

 

The 0445110034 is primarily associated with Mercedes-Benz vehicles powered by the OM611 engine family - a 2.1-liter and 2.2-liter, 4-cylinder common rail diesel that became the backbone of Mercedes' light commercial vehicle lineup.

Primary vehicle applications:

Model	Years	Engine	Power
Mercedes Sprinter 208/308 CDI	2000–2006	OM611.987	60 kW (80 hp)

Mercedes Sprinter 213/313 CDI	2000–2006	OM611.981	95 kW (127 hp)
Mercedes V-Class 200 CDI	1999–2003	OM611.980	75 kW (100 hp)
Mercedes V-Class 220 CDI	1999–2003	OM611.980	90 kW (120 hp)
Mercedes Vito 108/110 CDI	1999–2003	OM611	60–80 kW

The 0445110034 is part of Bosch's 0445110 series - a comprehensive range of high-pressure common rail fuel injectors covering all major OEM part numbers. Within this series, the 0445110034 sits alongside variants like 0445110035, 0445110045, and 0445110046 - each calibrated for specific engine applications and fuel delivery requirements.

What the series tells you:

0445110 - identifies the injector family (CRI solenoid injectors)

034 - identifies the specific calibration variant for this application

The series covers injectors from 0445110009 through 0445110966

 

 

The 0445110034 operates within a high-pressure common rail system. Fuel is pressurized by a high-pressure pump and stored in a common rail accumulator at pressures that can exceed 1,600 bar (23,000 psi) . The injector's solenoid opens to allow high-pressure fuel to flow through the nozzle, atomizing it into a fine mist for combustion.

Why the CRI injector matters:

Response time - the solenoid must open and close in milliseconds

Precision - even microscopic variation in injector performance affects fuel delivery

Durability - the injector must withstand millions of actuation cycles at extreme temperatures

 

 

The 0445110034 sits at the center of a cross-reference network that gives parts buyers options:

Number Type	Part Number
Primary Bosch	0445110034
Alternate Bosch	0445110201
Exchange Number	0986435063
OEM Reference	A6130700187
OEM Reference	A6130700587
OEM Reference	A6130700887

Why this network matters:

Sourcing flexibility - if one number is out of stock, another may be available

Cross-brand compatibility - aftermarket manufacturers often use different numbering systems

Inventory optimization - distributors can stock one injector and serve customers searching by any of these numbers

 

 

Injector replacement on OM611 engines requires attention to detail:

Depressurize the fuel system - common rail systems operate at pressures that can cause serious injury

Remove the injector - using the correct extraction tool for the OM611

Clean the injector bore - remove any carbon deposits or debris

Replace all seals and copper washers - these are single-use components

Install the new injector - with the correct torque specification

Code the injector to the ECU - each injector has unique calibration characteristics; the ECU must be updated with the injector's IMA code

Critical note: Coding is not optional. The OM611's ECU uses the injector's individual calibration code to compensate for manufacturing tolerances. If coding is skipped, the engine will run poorly, with rough idle, increased smoke, and reduced power.

 

 

Q1: What vehicles use the 0445110034?
It's used in Mercedes Sprinter (208–416 CDI), V-Class (200–220 CDI), and Vito models with OM611 engines. It covers power outputs from 60 kW (80 hp) to 115 kW (154 hp).

Q2: What's the difference between 0445110034 and 0445110201?
They're from the same Bosch injector family and are cross-reference numbers for the same injector. 0445110034 is one variant; 0445110201 is another that shares the same application. Both point to the identical Bosch CRI injector for OM611 engines.

Q3: What are the warning signs that my injector needs replacement?
Common symptoms include rough idle, loss of power under load, increased fuel consumption, excessive black or white smoke, and hard starting. A failing injector can cause damage to other components if left unaddressed.

Q4: Is coding required after installation?
Yes. Each injector has unique calibration characteristics, and the ECU must be updated with the injector's IMA (Injector Manufacturer Adjustment) code. If coding is skipped, the engine will run poorly with rough idle, increased smoke, and reduced power.

Q5: What's the warranty on this injector?
This injector comes with a warranty that reflects the manufacturer's quality standards.
