Graeme is their another Ford dealership any closer to home? You don’t have to use the one you got the car from.
you could get Guildford to order your repair kit and have it sent to a nearer dealer at the same time as getting them to run through the main controls again.
lesson learned the next car you order they are supposed to let you look over the car and test everything before you give your PIN number etc. I spent a good half hour fiddling and asking the guy questions.
