B8 Coolant warning

Post by Passaaat »

Hi folks,
The last couple of weeks I've been getting an intermittent "check coolant" warning accompanied by the red triangle and coolant symbol. I've checked coolant level and is fine. Doesn't seem to be any pattern as to when it happens, and not on every trip.
Having seen posts about the expansion tank level sensor I've cleaned the contacts on the connector and on an Mway test run yesterday no warning. Coolant temp at about 90 and oil temp between 96 and 101.
So, maybe it was as simple as that... but I have a longish trip next week and don't want to get caught out. What else could this warning indicate, and should I get a garage to check it out even if no further issues (won't be driving much before then)?
