Four years on, cheeky revive of this thread - it seems this fault has just occurred on my 2017 sportline 280. I'm near North London (Herts) I'll drop you a DM if that's ok. Full disclosure I'm very sadly now preparing the car for sale. It's been such a pleasure drive the last almost decade, I'm quite sad to be parting. And i guess it is too as it's chosen this week for the powered seat module to fail, and also a flat battery (perhaps related) I'm fairly sure it's the module, as the fuse is fine and the infotainment system is saying not currently available in all the seat preferences menus I should put the OBD scanner on it too, but I've not had a lot of success getting much out of that in the past
