My son has always liked Mini's so when he got out of the Marines, we got a British Racing Green Mini. It now has about 110K mile on it and was (it is a mini) running well. Until it wasn't.
After it over heated, we got the head rebuilt and replaced all of the wear and tear failure points (Water Pump, cross-over tube, thermostat, water pump pulley, belt, timing chain and tensioners). We got is all back together and it ran OK!!! Then we started throwing a code for a low temp issue.
I think we are going to need another new thermostat to resolve this issue.
Learning a lot about diagnosing and fixing these complex new toys. I'm using an XTOOL D9SPro and ISTA to debug things if anyone is interested.

Thanks
Peter
