Common Injector Failures on the CFFE

The CFFE engine uses high-pressure common rail diesel injection. Over time, injector nozzles wear, seals degrade, and internal components lose calibration. This leads to a range of drivability symptoms that worsen if left unaddressed. We stock 1 tested replacement injectors for this engine from Bosch.

Vehicles fitted with the CFFE include models from Audi, Seat, Skoda, Volkswagen. If you are experiencing any of the symptoms below, your injectors may need testing or replacement.

How to Test CFFE Injectors

Leak-off test: Connect clear hoses to the injector return lines and compare fuel volumes at idle. The injector returning the most fuel is likely worn.

Correction values: Use a scan tool to read injector correction (IMA) values. Readings beyond ±3 mg/stroke indicate wear.

Resistance check: Measure resistance across the injector connector pins with a multimeter. Compare to manufacturer specs.

Remanufactured, Reconditioned or Refurbished Diesel Injectors — What We Supply

Whether you searched for remanufactured, reconditioned or refurbished diesel injectors, the product here is the same: a professionally remanufactured injector, not a cleaned-up used part. Each unit is dismantled, inspected against the manufacturer's test plan, worn components such as nozzles and control valves are replaced where the bench results call for it, then it is calibrated, tested and supplied ready to fit with its coding data. We remanufacture in-house in the UK and deliver nationwide.

Is a reconditioned injector the same as a remanufactured one?

In UK trade language the terms are used interchangeably. What matters is the process: our injectors are fully remanufactured — dismantled, worn parts replaced where required, recalibrated on the test bench and covered by a 12-month warranty — rather than simply cleaned and resold.
