Bosch Fuel Rail Pressure Control Valve – 0 281 006 246 (BMW 13538508158)

Description

Bosch 0281006246 is a high-pressure common rail control valve (DRV/PCV) used in BMW diesel engines.
It regulates fuel pressure inside the rail to ensure precise injection, stable combustion, and consistent engine performance.

This is a genuine OEM Bosch valve, designed for high-load diesel applications including BMW’s M Performance engines.

Technical Details (important for your credibility)

• Type: Fuel rail pressure control valve (DRV / PCV)
• System: Common rail diesel (high pressure side)
• Control: Solenoid valve (PWM controlled ~1kHz)
• Default pressure (unpowered): ~100 bar spring baseline
• Function: Actively adjusts rail pressure based on ECU demand

👉 When energised:

• Valve reduces return flow
• Increases rail pressure instantly

👉 When not energised:

• Allows pressure bleed-off to maintain baseline

---

Notes

• Mounted directly on the fuel rail (high-pressure side)
• Fuel-cooled internal solenoid design
• Critical for high-load / high-boost engines (like M50d)

Common issues when faulty

• Hard starting or no start
• Limp mode (rail pressure faults)
• Rough running under load
• Power loss, especially at high boost
