Bosch 0445010463 High-Pressure Fuel Pump (0 445 010 463) – Rail-Pressure Stability For Fiat/Jeep 2.0 Diesel Platforms

A modern 2.0 common-rail diesel doesn't "run on fuel" so much as it runs on pressure control. When rail pressure is accurate, injectors can deliver clean, quiet combustion; when it isn't, you get hard starts, hesitation, smoke, and fault codes that look like anything but the real cause. The Bosch 0445010463 (0 445 010 463) high-pressure pump is engineered to keep that pressure stable on FCA-group 2.0 diesel applications-most commonly seen on Jeep Renegade, Jeep Compass, and Fiat Toro 2.0D/2.0 CRD variants.

 

 

0445010463 is a Bosch high-pressure pump for common-rail diesel systems, commonly described in catalogues with the Bosch internal designation CR/CP1H3/R70/10-89S.  
Its role is straightforward but critical: it takes low-pressure supply fuel and compresses it to the high pressures required by the rail, so the ECU can precisely control injection events. In daily driving terms, this pump helps deliver smooth torque during low-rpm pull, stable idle in traffic, and clean response when the vehicle is loaded.

 

 

Most customers don't search "Bosch CP4 pump for 2.0 TDI." They search by part number. Your page should prominently include:

Bosch: 0445010533 / 0 445 010 533 

VAG OE references commonly linked: 03L 130 755 AA, 03L 130 755 AB, plus related supersessions shown in listings  

Bosch reman/exchange references frequently shown by sellers: 0986437405 and 0986437420 (as restored/reman numbers in some markets) sindiesel.net

Why this matters: these number clusters match high-intent searches like "03L130755AB high pressure pump" or "0445010533 CP4 pump," bringing shoppers who are already close to purchasing.

 

 

Most customers won't type "Bosch high-pressure pump for 2.0 diesel"-they'll paste numbers from a quote sheet or the pump label. Common identifiers connected to this pump include:

Bosch: 0445010463, 0 445 010 463  

FCA / Fiat Group OE numbers: 55268335, 55274521 

Lancia OE number shown in cross-lists: 55263525  

Related component number often mentioned alongside the pump in listings: 0928400825

Online catalogues and major parts retailers commonly list Bosch 0 445 010 463 as compatible with:

Jeep Renegade (BU) – 2.0 diesel variants

Jeep Compass (M6) – 2.0 diesel variants

Fiat Toro Pickup – 2.0 diesel variants

Fitment listings frequently show around 170 hp / 125 kW 2.0 diesel configurations for these applications (market-dependent). 

Because trims and engine codes vary by region and model year, the professional best practice is: confirm the pump number on the unit + match the OE number in the OEM EPC or workshop quote system before ordering.

 

 

Independent-site customers want clarity: what will this pump improve, and why should they trust it?

● Pressure stability under real driving conditions
A healthy pump prevents rail-pressure dips that can trigger limp mode or throttle lag-especially noticeable on highway merges and uphill acceleration.

● Cleaner combustion support
When rail pressure is correct, injection timing and atomization improve, which can reduce smoke and help aftertreatment systems (DPF/SCR where equipped) operate more efficiently.

● OE-grade compatibility
Many listings emphasize genuine Bosch supply in original packaging for this pump, which matters for workshops trying to avoid comebacks on modern common-rail systems

 

 

To present your brand as a specialist (not a generic seller), add concise guidance:

◆ Verify numbers before purchase: 0445010463 / 0 445 010 463 and OE 55268335 / 55274521 / 55263525. 
◆ Fuel cleanliness is non-negotiable: common-rail HP pumps are extremely sensitive-replace filters and address water/contamination issues to protect the new pump.
◆ Post-install validation: proper priming, leak checks, and rail pressure confirmation with diagnostic tools help ensure the pump performs as intended.
