** UPDATE** hopefully the last one on this 🙂
So I arrived this morning at the garage to have the software installed and they were having issues with the software download etc so they gave me a hire car. Originally I was planning to wait whilst they did it but it was taking a little longer than expected!
They phoned me this afternoon and said they had difficulty installing the software but it had been done and they had been in contact with Mountune and Ford to sort it. However the car was still putting out error codes, so they spoke to them both again and then came to the conclusion it was the butterfly valve in the backbox, so they plugged in the new one they had there and all the errors went so got a whole brand new mountune axle back exhaust!
Everything was running smoothly on the way home swapping between sport and normal with the engine fully warmed up and a warm ambient air temperature.
I have to say credit to my dealer they have been very helpful sorting this matter out for me 🙂
