Common Rail Injector Repair

A Common Rail injector meters fuel in response to control commands, and a fault can affect starting, smooth running and combustion. Repair begins with bench testing to distinguish injector performance issues from supply or other fuel-system problems. Inspection then establishes repairability and the parts to be agreed. Cleaning alone cannot restore worn working surfaces. The assembled injector is tested again, with coding performed where its design requires it. You receive an assessment based on the test findings.

Symptoms

Uneven running or difficult starting of a diesel engine.
Injector performance deviations confirmed by diagnosis.

What's included

Carry out the initial injector bench test.
Inspect the components and agree on repairable items.
Complete the agreed repair and reassemble.
Retest and code where required by the design.

Additional checks

Fuel supply and other system components — separated from the injector fault via bench testing
Working surface condition — assessed separately from cleaning
Need for coding — depends on the injector's design

Why it matters

Incorrect metering can affect combustion and engine loading. Injector assessment needs to consider the condition of the complete fuel system.
