Hi all .. car is a 2014 Allroad with the 3.0 litre TDi (245 bhp) engine. in the past week it's started giving intermittent "low coolant - stop engine" warnings that last about 5-6 minutes then dissapear, only to come on again at some almost random time, although part of me thinks they come on more often going uphill and go out faster going downhill !!!!!!! A part of me also thinks the warnings only start once the engine reaches full operating temperature - on the gauge that is.

Level has, obviously been checked numerous times ... its halfway between MIN and MAX when stone cold ( 2°C last night ) and a fraction above MAX when fully up to temperature but with the warning ON !!

I don't have any access to a code reader.

Any ideas what the problem may be and what, if anything, I can do to resolve it please ???

Ta muchly
