0445010372 Bosch CP3 Common Rail Pump High Pressure Precision Fuel Delivery

Product Description

0445010372 is the CP3 product in this group, and that difference matters. We position it specifically for the VW/Audi 3.0 TDI BMK application stated in our supplied product material. Instead of describing it as another generic CP1 replacement, we use this page to explain why the pump family and engine application should be confirmed together.

Bosch's technical documentation explains that a common-rail high-pressure pump delivers fuel into the connected rail under high pressure, while the rail stores and distributes the pressurized fuel to the injectors. Our purchasing approach follows the same system-level logic: identify the pump first, then verify the complete engine/fuel-system configuration.

Product Snapshot

Application & Compatibility

We use the following application scope as the working reference for this SKU: VW / Audi 3.0 TDI BMK engine application stated in supplied product material. This does not mean every vehicle within a broad model family is automatically compatible. Before we confirm an order, we compare the complete pump number with the engine/application details supplied by the buyer.

CP3 application is the key identification point

The supplied product description associates 0445010372 with VW and Audi vehicles using the 3.0 TDI BMK engine. We therefore recommend using BMK and the complete pump number as the primary application checks. A generic “3.0 TDI” description is not sufficient for a purchase order.

What we look at before supply

We check the ordered part number, application information and product condition. For units processed through our hydraulic testing workflow, we inspect leakage, pressure stability and fuel delivery. This gives the buyer a clearer quality-control trail than a simple visual inspection.

Why pump family matters

CP1 and CP3 are not interchangeable simply because both are common-rail high-pressure pumps. The pump architecture, control arrangement and application must match the engine system. That is why we keep 0445010372 on its own product page instead of grouping it with CP1 numbers.

Workshop replacement guidance

Before fitting the pump, inspect the fuel supply and filter, confirm the connections and make sure the system is clean. After installation, verify priming, leakage and rail-pressure behavior. If a fault code remains, perform system-level diagnosis rather than immediately replacing the pump again.

B2B supply for European diesel specialists

We supply new and remanufactured options subject to stock, with neutral export packaging and technical matching support. For wholesale buyers, we can work from a part-number list and help separate CP3 products from visually similar CP1 products.

What We Check Before Shipment

• Exact part-number and label identification against the purchase order.
• Product condition: new or remanufactured, as quoted.
• Visual condition and obvious sealing/interface issues.
• Hydraulic inspection or bench testing where included in the supplied product/QC process.
• Packaging and labeling suitable for international B2B shipment.

For products sold as new or remanufactured, we follow our internal identification, visual inspection, sealing and hydraulic testing workflow. Where a bench-test record is required, we can provide the applicable inspection information for the supplied unit. We do not use a test claim as a substitute for checking the exact pump number and application.

Ordering Information

For a quotation, please send the exact pump number, quantity, engine code, vehicle/application, OE or cross-reference number if available, required condition (new or remanufactured), destination country and a clear photo of the existing pump label when possible. This information helps us reduce wrong-part shipments.

Our Company & Technical Responsibility

We are Guangzhou Zhuohang Auto Parts Co., Ltd., a professional supplier of diesel common-rail fuel-system components. We work with overseas repair shops, vehicle maintenance businesses, machinery service companies and distributors. Our role is not only to supply a part number; we help buyers verify the pump identity, application, condition and replacement requirements before shipment.

Our technical-sales responsibility is to help buyers identify the correct product, explain the relevant common-rail system considerations and communicate the condition and inspection scope of the unit supplied. We do not describe an aftermarket or remanufactured part as a genuine Bosch product unless genuine status has been verified.

Warranty & After-Sales

We provide a 12-month warranty for applicable products under our stated warranty terms. For a warranty claim, we normally need the order reference, part number, installation information, fault description and supporting diagnostic evidence. Our team can help distinguish a pump-related issue from problems elsewhere in the fuel system.
