What type of injector is DCR02501AA1?
It is a Delphi Diesel Injector (distributor-pump fed). Always confirm the OEM markings on the injector body before fitting.
Does DCR02501AA1 need coding when fitted?
No — the 1.9 D (DW8/DW8B) is an indirect-injection engine fed by a distributor pump, so no electronic injector coding is required.
What are the symptoms of a failing DCR02501AA1?
Common signs are rough idle and vibration, hard starting, power loss or limp mode, black smoke and an engine-management light.
What causes these injectors to fail?
Most failures come from poor fuel filtration, contamination and water in the fuel leading to wear, high back-leakage and nozzle coking. Fix the cause before fitting replacements.
Is a remanufactured DCR02501AA1 as good as new?
A properly remanufactured injector is stripped, fitted with new wear parts, reassembled and recalibrated on a common-rail test bench to OEM tolerances, then supplied with a warranty.
Should I replace one injector or the full set?
Replace the confirmed faulty injector first. On high-mileage engines fitting a matched set reduces the chance of a repeat fault, but it is not mandatory if the others test within spec.
Do you bench-test the injector before dispatch?
Yes. Every unit is tested for delivery, back-leakage and spray pattern on a calibrated common-rail tester before it leaves us.
Is delivery and warranty included?
Yes — the price includes free UK delivery and a 12-month warranty.
Is DCR02501AA1 a common-rail injector?
