The fact the fault was reported and not repaired before the warranty ran out, should mean you don’t pay for the fault to be repaired. Contact Ford Customer service to log the issue now. 0800 166 166vipr said:
I think it sounds a little more than the wheel sensors if you’re getting other erroneous faults too, like communication corruptions between devices, though this should be minimised in the error correction built in to the communication protocol. Its more likely to be something in a common unit that all these devices communicate with such as the central junction box. Not easy to find, but the guys at the garage if they are familiar with the communication system should be able to pin it down a common unit which looking at some drawings looks like the central junction box (behind the glove box). With so much going wrong which are unconnected with each other in their operation, I’d be plumbing to change that first or at least investigate it. Could be loose connection or electrical dry joint whch tend to show themselves when temperatures are at extreems. As a matter of interest, try turning the heater on full to warm the area up and see if that induces it.
But with all due respect to the technicians, they don’t inspire me that they use lateral thinking.
