Our 2.0 hdi has recently started overheating. It overheats within a very short driving distance. 5-10 miles.

I don't have any bubbles in the coolant reservoir, but when i go for a drive the coolant in the reservoir is getting hot and becoming pressurised and appears to leak out of the coolant cap when driven. (but not when left idling on the driveway)

I have already changed the thermostat (£300 only available from citroen) because i went to inspect it and the design is so poor that it dissintegrated upon removal. A new thermostat has not helped sadly.

It was only after replacing the thermostat that I also noticed, no interior heat from the HVAC fan and the radiator fan not kicking in even when overheating..... (its the wife's car, i only drive it when there's a problem!)

I'm hoping this is a simple coolant temp sensor or fan speed control problem rather than leaking head gasket gases pressurising the system.

Any hep greatly appreciated.

I did see your thread and thought the symptoms sounded similar. A new coolant cap solved your woes?

Cheers

If anyone else has this issue, the cap is a simple cheap fix. However, there is a software update for the 2.0HDi cooling parameters. As I believe there is a recall for this, it may well be free.

Hopefully Solved! Just went for a quick test drive armed with my new coolant cap, car didn't overheat on the same route it overheated on recently. And when I checked the coolant reservoir it had normal looking levels! previously when the overheating warning came on my coolant reservoir was full and angry looking!

My interior heat hasn't come back, but having spoken to Citroen there are no less than 3 recalls outstanding; urea cap, engine cooling parameters software update as mentioned above, and something to do with the interior cabin heat. so hopefully the lack of interior heat relates to this recall. All booked in to be completed next week.

I will leave my scan gauge obd2 cable plugged in for now and monitor the temps on a good motorway thrash before I hand the car back to my wife.

I have to say the lack of a coolant low sensor on this car is a serious design flaw. Shame on you Citroen.....

If anyone reading this suffers coolant related symptoms, go buy a coolant cap before contemplating going after the thermostat, (which is electronically controlled with an actuator anyway btw) foolishly i didn't have much time to research our issue before jumping in and attempting to stick the thermostat in some boiling water to test it. Such is the pants design I would challenge anyone to get the thermostat housing off without breaking it!

Many thanks to all that helped me from getting my pants pulled down and the local dealers. (for now at least!)

Excellent news, they tried a new cap and bottle on mine but sadly it didn’t help - hopefully it is this simple.

Agree on the coolant level warning, my 15 year old Audi (itself a 20 year old design) has one!

I have had the first two done, but not heard of the third. Mine is due for service and MOT in two or three weeks. Hopefully it will be done then if it is necessary.
