What this kit is for

Intended to replace the six injector-driver MOSFETs when diagnosis confirms a MOSFET output-stage failure.

Possible associated fault codes

30BA, 30BB, 29CD, 29CE, 29CF, 29D0, 29D1, 29D2, 29CC and 29D9.

These codes do not prove that the MOSFETs have failed. Injectors, coils, wiring, power-supply faults, software and unrelated DME damage can produce similar symptoms.
