Anyone got a picture of the other end of the heater cable. (Heater box). I had the garage look at my control as over the winter it has got very very stiff. I can’t turn it one handed. Garage spent an age on it. (Labour cost OUCH) but they are still unhappy with it. Whilst they do not think it needs a new cable, but the core cable/wire needs withdrawing and lubing. This apparently means heater box out so many many hours Labour. I am looking at doing it myself, but can not find any diagrams etc to study. Note on the 2011 4/4 the cable only operates a flap. The matrix apparently is permanently on.
