Common Failure Symptoms
Before replacing, confirm the fault. Signs that point to a failing 0445010685 high pressure fuel pump include:
- Hard starting or long crank before the engine fires
- No-start or stalling under load with a low-rail-pressure fault (DTC P0087 / P0088)
- Loss of power, limp mode and an illuminated check-engine light
- Rough idle / misfire from unstable rail pressure (DTC P0191)
- Whining or grinding noise from the pump under load
- Metallic debris in the fuel after a catastrophic CP4 failure that spreads to the injectors and rail
These symptoms can also arise from related components, so verify the fuel pressure and electrical supply before fitting a new unit.
Installation Notes
Isolate the fuel system and relieve residual rail pressure before removing the pump. Match the new unit by the OE number printed on the old part and the engine code on the data plate. If the pump has failed internally and shed debris, the injectors, rail and lines must also be inspected or replaced, or the new pump will be contaminated immediately. Torque the drive and fuel connections to spec, prime the system and check for leaks and correct rail pressure after fitting.

Frequently Asked Questions
Is the 0445010685 a genuine Bosch part?
No. It is a compatible replacement CP4 high-pressure pump supplied under the Vidishi Auto brand. It is built to fit the applications listed but is not made or endorsed by Bosch; the Bosch mark is used only to describe compatibility.
What does the 0445010685 replace?
It replaces the Bosch CP4 high-pressure pump 0 445 010 685 and the related CP4 numbers 0445010686 / 0445010673 / 0445010659 and the VW/Audi 059130755-series. Match by the OE number on the old part.

Selected 2.7L and 3.0L TDI common-rail engines, including Audi A4/A5/A6/Q5/Q7 and the VW Touareg 3.0 TDI. Confirm with your engine code.
Why do CP4 pumps fail?
The CP4 is lubricated by the diesel fuel itself. Low-lubricity fuel, contamination or water can cause internal wear that sheds metal debris, so a failing CP4 often contaminates the injectors and rail at the same time.
What is the maximum rail pressure?
The CP4 platform is designed for common-rail systems up to about 2,700 bar. Confirm the exact rating for your engine before ordering.
How do I confirm fitment before ordering?
Send us the OE number from your old pump or the engine code on the vehicle data plate and we will confirm the correct CP4 variant for your VIN.
