Welcome to the Club, Phillip.


There are a lot of helpful members who will offer you their experiences.


You can download an owners manual from the internet, and I am sure that there are some genuine ones out there that you could possibly find on eBay or Gumtree.


The intermittent parking sensor could be which could be over waxing and could be cleared with some car shampoo and warm water. It could also be one of the four sensors or the way out, which happened to me on an x type over a year ago.  A replacement will cost about £20.  Finding which one is a bit more difficult.


The air conditioning unit is a bit more difficult, and these days I do not get oily hands, so my inclination would be to look in the piggy bank for £40 and take the car to one of these places that advertise regassng the unit.

Hi Phil. just reading your post and in particular your 'big' problem, you say there is no water in the lower hose, if this is the one that feeds the heater matrix then I think it would be safe to assume something is blocked or water is unable to get there. It is unusual that you are not reporting over heating problem as this would point to the thermostat. Are you sure that the water is circulating, holding one of the pipes and revving the engine you should feel a surge or increased pressure on the wall of the tube, this would therefore indicate that the pump is working ok.


I would think that an 05 car would have at some point had the coolant replaced, therefore I can't really see it being a blockage or an air lock as you would hear bubbling & gurgling noises.


I would start in the cheapest and easiest place, the  thermostat bud.

Hi Phillip,


Hope its gets sorted.


Never mind punctuation ---  the important bit of language is understanding the message.  I understood it without any problem.


Let us know how you get on, as all experiences are useful.

aye up Phildog, don't get down on your grammar dude, we are all here to help and the benefit of our experiences. More importantly lets try and get the issue sorted.


As far as I am aware a regassing of the air con unit only affects the air conditioning ie the cooling system.


If you are not experiencing overheating then the problem could be an electrical one as this controls the mechanical 'flaps' that, if faulty could be permanently in the shut off position, thereby inhibiting the flow of warm air into the cabin. I had a similar problem with a Fiat Tipo my daughter had, the control had broken and the car was freezing through one winter I remember, I went straight to the heater matrix and changed that but it made no difference.

Just done a quick search Phil, basically if you have a thermostat that is stuck in the 'closed' position this causes the car to overheat, if its stuck in the 'open' position the water keeps circulating building up very little heat causing no heat out put to the heater matrix.


So, when you first start your car the stat is in the closed position allowing the engine and cooling system to reach optimum temperature for running efficiency, when this temperature is reached it then opens allowing you then to use your heating in the cabin.


I think this makes more sense and that the cause of your issue is still the thermostat in my book. As for how to change it, a Haynes manual, youtube search or similar should be out there somewhere bud.

Hi phildog,another possible cause could be the heater valve,i believe it sits near the bottom of the radiator,these have been troublesome from posts on another forum i have read.

I always go for the cheapest item to look at first,as the previous posters have said,might be worth changing the thermostat first then look at the more costly item,heater valve as i believe they are not cheap.

good Luck

Graham :D

Hi there phildog I had a intermittent rear parking sensor fault it only worked if you held the gear leaver in reverse and it was just the switch on the gearbox for the reversing lights that also power up the rear parking sensors,I got a new switch on eBay for a ten pounds and it now works fine.

I think that your heating problem is the control valve not opening ? Why not get your self a inferred thermometer about £ 15.00 and you can check out the temperature of all pipe work and see we're the heat stops.
