    Hi everyone,
    2007 R55 Cooper S
    I am getting the temp warning when car is under load usually uphill.
    Has had the following work done, cylinder head rebuilt, new thermostat housing, water pump and radiator, bottom end has also been rebuilt.
    Thermostat housing (genuine mini part) has been replaced again and I am still having issues.
    Can anybody suggest anything to be checked. What I will say is I have a Bluetooth elm327 which shows temp going to 120oC which flags up the warning then within around 5 seconds temp drops to around 95oC
    Any suggestions would be appreciated
    Davie

    I take it you’ve checked coolant levels? Also made sure that the system has been bled properly

    Been back out to check coolant level, would appear to have coolant forced out of cap as droplets of coolant on the underside off the bonnet, thinks I may have to bleed system again

    To help anyone else in the future, turned out to be fault ambient temperature sensor. This was related to fault code 2f22 hope this may help someone in the future.
