Saturday & Sunday the Defender started to play up. It's running fine with no warning lights, but the water temp dropped off the scale of cold. Pulled up and the gauge climbed back to normal. Noticed this happens whenever there is no load on the engine. I read somehwere that if the temp sensor is faulty ecu calculates the temp from the fuel cooler. Could it be a faulty temp sender before I started buying parts in the hit & hope scenario?
When it's stopped in traffic and the gauge is moving around, does the heater still blow hot?

I ran a cable from the earth ECU to the battery earth this morning. All ok on the way to work. Is that ecu earth just through the metal work of the seat box, there isn't an earth strap to the chassis, is there?
