What is common rail diesel and why does pressure matter?
Common rail diesel systems pressurise fuel to 1,600–2,200 bar (vs 250 bar in old diesel systems) — this ultra-high pressure enables a fine mist injection that burns more completely. When rail pressure drops below 1,200 bar at full load, the ECU reduces injection quantity, causing P0087 and severe power loss. GarageNation tests the full high-pressure circuit before condemning any individual component.
How do I know if my diesel injection pump has failed?
Symptoms of HP pump failure: P0087 code, hard starting, and pressure staying at 800–1,000 bar instead of reaching 1,600+ bar under load. GarageNation performs a comprehensive pump output test — measuring delivery volume at specified RPM and pressure. CP4 pump failure (common in Ford 2.0 TDCi and VW 2.0 TDI post-2011) often sends metal debris through the entire fuel system.
Is common rail pressure test covered by car insurance in India?
Standard comprehensive motor insurance covers common rail pressure test only if the damage was caused by an accident or a specified peril (fire, flood). Mechanical failure from wear is not covered. Some premium insurance add-ons (engine protect, gearbox protect) do cover diesel injector failures — check your policy document. GarageNation provides detailed repair reports for insurance claims.
