Also the 2 coolant sensors-blue one to ecu, and black one to guages can be checked by taking live readings from my obd diagnostics. I also have the use of a thermal imager which can read any part of the engine for temperature, which may be useful, and I obviously need to check all my wiring again. May get a look tonight when little one asleep.... he wants me to drive him to school in it soon... no pressure!

Are you using the BMW sender connected to your Smiths gauge, or have you fitted a Smiths sender?
