Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 1.6 TDI run rough?
A worn or leaking injector unbalances fuelling; read live correction data and bench-test the weak cylinder.
What causes these injectors to fail?
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured 28565336 perform like new?
A properly remanufactured injector is bench-tested and recalibrated to the Delphi plan, then IMA-coded on fitment.
