0445010381 Bosch CP1 High-Pressure Pump 3-Plunger Diesel Replacement

Product Description

We supply 0445010381 as a CP1 high-pressure common-rail pump. 0445010381 is listed in the supplied application data for Audi/VW 3.0 TDI engines using the ASB/BKN engine codes. Because fitment can vary by vehicle configuration and fuel-system specification, buyers should confirm the complete pump number and engine code before ordering.

Product Snapshot

Application & Compatibility

We use the following application scope as the working reference for this SKU: Audi/VW 3.0 TDI ASB/BKN wording appears in supplied product description; final fitment requires verification. 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.

Pressure generation and rail supply

A common-rail high-pressure pump feeds the connected rail, which stores pressurized fuel before the injectors receive it. Bosch describes this relationship as the core hydraulic architecture of common-rail systems. The pump therefore has to be evaluated as part of the complete fuel system, not as an isolated mechanical component.

Inspection and product condition

Our source material specifies hydraulic bench testing for leakage, pressure stability and fuel delivery, and lists new and remanufactured options. We confirm the actual condition and available inspection information for the unit quoted to the buyer.

Important fitment caution

The source documents contain conflicting or overlapping application data among related part numbers. We therefore do not recommend using a generic Audi/VW 3.0 TDI description as the sole purchasing criterion. Confirm the complete pump number, engine code and OE reference before order confirmation.

Support for wholesalers

We can support repeat buyers with part-number-based quotations, neutral export packaging, flexible MOQ and technical matching assistance. This is particularly useful when several CP1 numbers appear similar in a distributor's inventory.

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.

FAQ

Q: Is 0445010381 definitely for every Audi/VW 3.0 TDI?
A: No. The supplied material associates it with ASB/BKN, but exact fitment must be confirmed from the actual pump and vehicle/engine information.
Q: What specification is listed for the pump?
A: The supplied table lists CP1, up to 1400 bar and three plungers; verify the actual unit before making a product-specific technical claim.
Q: Can you provide new and remanufactured versions?
A: Yes, subject to stock and the condition agreed in the quotation.
Q: Why is a label photo important?
A: It lets us verify the exact part number and visible configuration instead of relying on a broad engine description.

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.
