You will find it on the r/h/s by battery, it's on the end of the head block inside the plastic cowling that has about 5 pipes connected to it. Remove air resonator pipe that feeds rear of engine to give you access. Its a green electrical plug and when you refill coolant remember to bleed correctly.
the bleed screw is on the top near the sensor. theres 2 coolant pipes going to it with a dust cap on the end. make sure the heaters on full to bleed it
just be careful when fitting my one the bit where it clipped in broke away. breakers dont like to sell the thermostat housing on its own and you need to replace the seal at the back which is a nightmare
There are two nipples on this engine, like monty mentions one on the (Thermostat housing) the other is at rear of engine on the pipe that feeds the Matrix (heater) you need to remove the resonator pipe and that will give you clear access to the nipple...like the caps on the wheel valves.

And what is the program for that

thanks to all
I have a peugeot 307 1.6hdi 9hz , engine starts fine, idles well for about 5 seconds and starts bucking then knocking really loud then stalls. Diagnostics are showing the engine starts at around 300bar then slowly rises and the engine cuts out at 1700bar!
I have a citroen c4 with the same...
I'm going to be changing the Cat out on the car soon and want to replace the O2 sensors while I'm under there and the cat is off (hopefully improving the MPG)
My question is - where on earth do you disconnect the sensors? From under the car the wires disappear up towards the exhaust...
