Possible coolant smell??
We have a 2013 Cooper SD Auto that we've had from new. Recently I've noticed a sweet smell in the car after its not been used for a few hours/overnight
I think this smell is coolant, but I can't find any leaks or feel any leaks in passenger foot wells (i was thinking a faulty heater matrix or core). I've been marking the coolant tank and there is no visible change or loss in coolant.
I also can't smell coolant though the vents.
The heater is working normally and the car is driving OK.
Before I take it into the garage, is there anything else it could be?
