I'm topping my coolant once every 2-3 months with around 300ml .
I know the thermostat has a very small leak,I checked again yesterday after a oil change,and both leaks are where the screws are fitted through the housing to the engine,do I leave it until it gets worse?(been like this 2 years) I think it's still on original factory one,as it's only ever been to Audi and they have no record of replacement,or do I change it, just wondering with the pfl not having a temp gauge.
