I have a small issue on my 4200 CC, where the F1 pump does not prime when the car is unlocked (whereas it previously did!).
We have hopefully traced the source of this problem to the Transmission Control Unit (TCU) which is not sending the signal to the F1 pump to prime (whirring sound on unlocking the car).
While it seems fairly easy to replace the TCU, getting access by removing the battery, my question is; does a new TCU need to be programmed or setup to work with my car, or does it come ready to plug in and just work (so you just remove the old and replace with the new?).
I read mentions about software updates for different versions (year) but don't know where the software update would be installed.
Thank you, any thoughts most welcome.
