I am only getting hot air out of my nearside (RHD air vents, even with a/c on. Got a feeling it will be expensive. Any ideas? It"s an unusually hot September here in the UK.

I have been told it could be a head gasket, there seems to be air in the system. I really hope not, as I know this could be expensive. The coolant level is low, when I release the pressure cap, it comes back up. Where's it hiding?? There are bubbles in the return tube (the small one, I think is a bypass, at the bottom of the bottle.

Not sure if this is the correct area, here goes. The heater on my 2015 1.6 diesel Connect Tourneo is blowing cold. On occasion, the engine temperature rises and the motor loses power, then within about half a mile returns to normal. The cooling fan runs pretty much constantly. Help! Please, I'm sure someone has the answer!
