Well my garage man changed the heating panel probably thinking same, it made no difference. However, external temperature sensor, you may have something there! Thanks I'll relay this to my man

When the temperature outside exceeds 18/19 degrees the dash board lights go crazy flashing and the needles fluctuate, the indicators, electric windows and locking system all fail while they are flashing. Been to garage, had new computer system installed and a complete new heater panel. Problem...

Thanks, I have a Freelander 2 TD4 HSE 2007

Thanks all for my welcome. My apologies for not stating which "beastie " I have. I had put it on my profile and forgot to put it here. My Landrover is a Freelander 2 TD4 HSE 2007
