Hi I have a bmw 116i sport f20 model and I’m getting no heating it’s get Lukewarm but not hot I’ve changed my thermostat and coolant temperature sensor housing. The car doesn’t over heat,I do believe the head gasket is not gone. Has anyone got any suggestions of what more I can try

What makes you believe head gasket is gone other than poor heating?
Have a check of the feed and return hoses to heater matrix where they go through the bulkhead. You could just have a control issue on hvac system rather than poor coolant flow/heat in matrix.

I don’t know was just think of things but I ended up fixing the problem the feed pipe to the matrix’s was blocked now everything works all fine

Try bleeding it again.
Also did you fit a genuine stat i have known a circoli one fail in under 15 minutes once.
Only use oem stats.

Yeah I’ve done the and yes I got an one thermostat I have heating now but it better on the passenger-side and with the bleeding is it self bleeding or normal

Should have a plastic screw in the pipe to bleed.
Not self bleeding.
