Hi all, am seeking any guidance on replacing the ECC in my 54 plate Signum.  Various functions still work, but others don't.  Has anyone done this?  I see on other forums there are various versions of the ECC and ideally want this to be a straight swap with as little hassle as possible.  Any and all advice / guidance very much appreciated!

Many thanks, Ian

It could be a fault with the control panel so maybe just swap it out and see if more functions work afterwards.
Replaced one on a Honda recently and it worked fine without any programming
