Bosch 0445010868 High-Pressure Diesel Pump (0 445 010 868) – CP4 Precision For V6 3.0 TDI Platforms

If common-rail injectors are the "sprayers," the high-pressure pump is the pressure author-it decides whether your 3.0 TDI runs crisp and quiet, or starts hunting, rattling, and triggering rail-pressure faults. The Bosch 0445010868 (0 445 010 868) is a CP4-family high-pressure diesel pump designed for modern V6 3.0 TDI applications across the Audi/VW ecosystem, where stable rail pressure is essential for clean combustion and emissions hardware longevity.

 

 

This unit is commonly referenced as a Bosch high-pressure pump for CR systems, identified in catalog listings with the CP4 designation and trade naming like CR/CP4HS2/L90/40. eBay+1
In practical terms, it pulls filtered diesel from the supply circuit, compresses it to the extreme pressures needed by the rail, and keeps that pressure stable as the ECU commands rapid changes in injection quantity and timing.

 

 

Buyers almost always arrive by part number. Your product page should prominently include these identifiers:

Bosch: 0445010868, 0 445 010 868  

Bosch exchange/reman references: 0986437480 and 0 986 437 480 (commonly listed as Bosch Exchange pump equivalents)  

VAG OEM references frequently linked: 059 130 755 DF (also seen alongside related variants like 059130755DB in pump families) 

Including these numbers helps capture real queries like "059130755DF high pressure pump", "0 445 010 868 CP4", and "0986437480 Bosch exchange pump".

 

 

To keep the copy professional and conversion-friendly, focus on what technicians and parts managers actually value:

✔ OE-grade control of rail pressure
A healthy pump supports consistent pressure under transient load-critical for smooth acceleration, reduced smoke, and preventing rail pressure deviation faults.

✔ Designed for modern 3.0 TDI combustion strategy
On V6 3.0 TDI engines, pressure stability impacts everything downstream: injector accuracy, combustion noise, and aftertreatment performance.

✔ Clear interchange and exchange options
Some customers specifically prefer Bosch Exchange units (core-return programs), so listing the exchange reference 0 986 437 480 alongside 0445010868 can capture additional high-intent searches

 

 

Even when you don't publish full pump maps, a few "trust specs" help:

Trade designation commonly shown: CR/CP4HS2/L90/40  

Example listed pump weight for the same CP4 family: around 5.04 kg (varies slightly by variant/packaging) K Motorshop

Common packaging identifiers/GTIN appear on related catalog pages (useful for buyers validating authenticity).

 

 

Including symptom language improves SEO and helps buyers self-qualify:

Hard starting or extended cranking (especially warm)

Loss of power under load, "flat" throttle response

Rail-pressure related fault codes / limp mode

Metallic contamination found during fuel filter inspection

Rough idle that isn't solved by injector replacement alone
