Why does my 1.6 HDi vibrate at idle?
A worn or leaking injector unbalances fuelling. Read live correction values and bench-test to confirm the faulty cylinder.
What causes these injectors to fail?
Per Bosch, poor fuel filtration, fuel contamination (including water) and incorrect installation - so fix the cause, not just the injector.
Do I need to replace the fuel filter when fitting injectors?
Yes - poor filtration is a leading cause of failure, so replace the filter and clear any contamination to protect the new injectors.
Should I replace one or all four?
Diagnose each with live correction values and a bench test; on high-mileage DV6 engines failures often cluster, so check all four.
Why renew the copper washer?
It is a one-use crush seal; missing seals or reuse cause blow-by and carbon build-up around the injector.
Does a remanufactured 0445110239 perform like new?
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan to meet original delivery and back-leakage specs.
