Hi, new to this forum so first post recently bought a fabia vrs and on two occasions on cold start up only when below minus degrees the coolant warning light has flashed and stayed on, it does go off once the engine has got to temp and Beeen switched off and on? Coolant levels are correct and have seen no sign off leaks or coolant dropping below min level, I have read other topics maybe relating this to requiring a new header tank would this be correct? Many thanks to anyone who could maybe help

new header tank normally solves this not too dear at around £25 and fairly quick to change

maybe worth trying topping up to the full mark when cold also ....
