Hi Guys,
My 1,6thp RCZ is not reaching engine temperature, thermostat staying open, have replaced it twice and at some point (last winter) it was all working again. Now this summer have the same problem and the A/C is also not working, can do an OBD2 reset, no errors but everything starts working again. I have read somewhere when the engine won't reach temp it will block the A/C. Have also done BSI Rest and it worked for 4 or 5 engine starts but eventually same problem. Thermostat open and no A/C.
Thanks
Brian

What make/brand of thermostat housing have you fitted (if not original)?
I have heard some have issues with some.
I have Mahle and no issues to date 🤞
