This box should give out fault codes
activate the ehr, amount of time it blinks fast for the first number, then 1,5s break and then fast blinking for the second number.
For example blink blink blink ......BREAK....blink blink blink blink is Code 34
This site is in german and I dont have time to translate if you translate it in chrome its good enough in my opinion

Your controller has short that's why is trying to restart.
It will not give you any error code on stage.

Ok, so will that be most likely on the power supply or on another component, for example a sensor or potentiometer? The negative battery terminal is needing replaced , wonder if that has caused an issue somewhere

If you have two faults together it will shut system down e.g. A draft pin and the potentiometer.need to stab in the dark and replace one of those if that could be possible to get it semi working to see blink code for other fault.did it have any codes before it faulted completely?if so a good place to start!

It was working fine on Sunday, parked up....then went to yesterday and not working....two lights on the box and relay tripping in and out as soon as you turn on the ignition. I'll try that and see if I can get any indications.....

It get colder recently. Bad joint, condensation, corrosion in one small place can kill anu electronics.
I can have a look if is anything obvious without promising, I have nothing to test it.... It would require armrest, ebox, sensors and solenoids.
But I can check if is alive.
