Hello everybody. I just bought a 2010 Mini Cooper Clubman S - turbo. The "Check Engine" light is on. I had the trouble codes read and there were two: PO597 & PO141. The 141 is the O2 sensor after the catalytic converter. The 597 is to do with the thermostat / cooling system; the thermostat may be OPEN too much. I have not measured the operating water temperature yet, but the engine seems to run cool - probably too cool. I figured that I would address this code first. I presume that I need to replace the thermostat, but it seems that most of the parts places offer the complete thermostat housing assembly for around $140. The housing assembly contains two temperature sensors: One is round, and held into the housing with a clip and sealed with an "O" Ring; The other is built into the housing and measures temperature on one of the necks connecting to a hose.
But with all the above, I am not sure whether I am getting to the source of the trouble code. Is there a conventional mechanical thermostat somewhere else? I am not seeing how the flow of water is controlled by anything in the housing assembly. Questions:
* Do you think the thermostat is the problem?
* If so, then where exactly is the thermostat that I need to replace?
* Is there any way that the 597 problem may be causing the 141 O2 sensor code to show a false code?
* Where is the best place to purchase a Service Manual for this car?
Thanks to anybody who can offer any information.
