Limp mode

Hi guys ,my disco TD5 has got an intermittent problem the two green lights keep coming on after I start the car only does it when I have left the car unstated for a long time it has got a new XYZ switch it clears if I switch off put it in park and restart the car its gone any ideas Loz

XYZ switch electrical system very voltage sensative, only needs to drop while cranking engine to cause flashing green lights and limp mode which in turn will only clear when the ignition is turned off.
Check the condition of the battery.

Thanks for that ,I was thinking that it might be battery ,not used much with the pandemic, if I have the heater on it does it so I might try a new battery thanks again Loz,

Thanks for this thread.
Mine did it yesterday for the first time. I have been turning the ignition on, just to wind the windows open a crack to air the car, then back on again to close them, over a few days.
Better make sure it still starts!
