The 1.6 TDI common rail of the Volkswagen group: Polo, Golf, Passat, Caddy, Audi A1 and A3, Seat Ibiza and Leon, Skoda Fabia and Octavia, in the versions where the knock is a known pattern. The exact software version is checked on the read.

Do the injectors have to be replaced?

Not if they are within tolerance: the diagnosis checks them before the patch. A faulty injector is a repair, not a software job.

Does it change the power?

The patch alone does not: it corrects the behaviour. If you want more power as well, it comes together with a Stage 1 calibration.

The symptoms

Metallic knock from the injectors, worse on cold starts and in the first minutes.
Engine that stumbles or hesitates when accelerating, with no fault code or with intermittent injector codes.
Uneven idle, "diesel knock" that comes and goes with temperature.
A dealer visit that proposes a software update or the replacement of injectors that are not faulty.

What the patch does

On the calibration, not on the partsThe patch acts on the injection management parameters in the ECU, where the behaviour originates. Injectors within tolerance stay where they are.
Developed and tested by MasterTuningWritten on the original map of each software version, checked on the dyno and on the road, delivered as a stand-alone file or together with a Stage 1.
Stock file keptThe original file is archived before writing: the car can always go back to stock.
