U1035 - missing/incorrect data for primary ID

Hi,

I’m Ben. I bought a 2013 mk6 fiesta 1.6 ST about 18 months ago. Over the last year it has, once every 1 or 2 months, gone into limp mode and the Coolant temp shot up. I’ve checked the coolant and it’s at a normal level. I’ve had to restart it and it’s been okay but when I code read it nothing comes up. Today, after it had been sat for 3 days, I started it, the engine lights come on and the coolant temp shot upon the dash. Limp mode followed. However this time it is permanent. I’ve code read it and code U1035 - missing/incorrect data for primary ID and cylinder heat protection were there. When cleared, they return after 30 seconding if the engine is running. 
Has anyone had this problem and if so could you please tell me what you did to fix it as the car is unusable until I can.

kind regards,

ben
