Can anyone help in the location of this sensor on my 1.6 diesel tepee. I have rapid temp spikes/dips. Car temporarily goes into limp during this phase. Informed its most likely failing ect sensor. Is it easy to swap out yourself?
What year is your car? IIRC, the thermostat housing with the sensor is between the battery & the engine on the 1.6 M59 (2005-2008 ish). They are easy to fit, a search for something like "1.6hdi temp sensor" should show up what you need.
