Thanks Rowlers,
I used the ‘apps’. Having finished and having the fault, I have ‘opened’ and ‘closed’ service mode a couple of times with no change to the fault.
When trying to go through the basic settings via the menus to start/end the lining change mode it’s asking me to upgrade to PRO. I’m happy to pay for it if need be, but as I haven’t need Pro for the 8 years I’ve had the car, if I can get around with a little help from someone it would be greatly appreciated.
