My vehicle is a VW Polo TSI comfortline 2016. I initially started noticing a problem when it told me that I need to fill my coolant. I left it for a while and I kept filling up the coolant. Until yesterday it gave me the notification again and before I could fill it up my car gave me me a notification that it is overheating. I stopped it at a petrol station and I filled the coolant but I didn’t want yo drive it as it was boiling in the bottle. I left it for the day and when I went back the temperature was normal and my coolant hadn’t run out during the day but as soon as I started driving my coolant finished but my car wasn’t overheating. The temperature gage did at one stage rise on my way home but it quickly dropped back to normal temperature and it didn’t rise again but I did have to fill the coolant.
