Mini Cooper S coolant warning but the coolant level is fine – what gives?
This is driving me crazy. My 2016 Mini Cooper S has started showing a "low coolant" warning on the dash, but when I check the expansion tank, the level is right between the marks. It happens mostly after I've been driving for a while and then restart the car. The temperature gauge stays normal. I've read online that these Minis have a common issue with the coolant level sensor going bad. I found a page for Mini repair https://800sayara.com/mini-cooper-repair-dubai/ and I'm thinking of taking it somewhere that knows these cars. Has anyone else had this issue? Is it really just the sensor or could it be a sign of something worse like air in the system or a small leak? I've looked for leaks and don't see any puddles under the car. The car has 95,000km on it and I've never had cooling system issues before. Also if it is the sensor, can I replace it myself without draining all the coolant? Any tips on where the sensor is located on the B48 engine? I'm trying to avoid a shop visit for something simple but also don't want to ignore a real problem. Any advice from other Mini owners in Dubai would be great. Thanks.
