Does the EA288 injector need coding?
Yes - write the injector correction (IQA) value to the correct cylinder with VCDS/ODIS when fitting, or the ECU cannot trim that injector correctly.
What are the symptoms of a failing 0445110468?
Rough idle, vibration, hard starting, black smoke, power loss or limp mode, an EML and higher fuel use.
Why does my 2.0 TDI 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?
Poor fuel filtration, fuel contamination (including water) and back-leakage wear - fix the cause, not just the injector.
Should I replace one or all four?
Diagnose each with live correction data and a bench test; on high-mileage EA288 engines failures often cluster, so check all four.
Do I need to renew the seals?
Yes - renew the combustion seal and clamp hardware; reused seals cause blow-by and carbon build-up.
Does a remanufactured 0445110468 perform like new?
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan to meet original delivery and back-leakage specs, then coded on fitment.
