So I bought my first mini in the summer but have had non stop problems with overheating since. If I drive it for 5 mins in stop/start traffic it boils over and loses coolant. So I have replaced the following so far but still no fix:
- Thermostat harness/ wiring
- Temp Sensor
- Expansion tank/ 2 x caps
- Water Pump
I have also taken it to a garage to check the head gasket and that all seems fine. They seems to think it could be a faulty ECU because the fan is coming on too late. One more thing to note is the temp gauge in the car isnt readin properly (barely moves even when overheating).
Any ideas welcomed and I can't think of anything else
Thanks in advance,
