Yeah my thoughts regarding the dealer exactly, TCU diag pass i found fishy as its all controlled within the car fordpass app settings the Vehicle hotspot and connectivity settings options which both dont work since feb. Also when you try to get into the vehicle hotspot settings for sec it displays a mobile signal meter icon top right corner of which has red X in it like you get on mobiles with bad sim or broken phone so that made me suspicious of the dealers feedback on the TCU issue!! (Dont know if this relates to TCU but the Modem Serial number is missing too)
Thanks again for all your help. Def taking to diff dealer!! Just so frustrating seeing as its less than 1 year old and we made sure all the optional extras were added to it. Connected Vehicle Features were great while they worked lol
