Could be low on gas, only costs a few pounds to find out.

 

Thanks I was wondering that myself but expected INPA to find an error or would low on gas not trigger one?

 

Seems INPA does not detect low gas as it was found to be low on gas

 

Do you know what the gas is called think am having the same issues and can't seem to find the gas anywhere

 

Hi mate, Iv got the same problem, number ten on my checklist to fix��. Some one has posted this on You Tube, an American chap who says it stems from the little thermostat bottom left of the car ( with the engine in front of you), that sits up right on the elbow of the bottom hose for the rad, this is also connected to the black box that sits on top of the fan shroud think this is the aux fan relay. (Nathan's Garage is his tube name)
Hope this helps fix the prob��.

 

Hi Mate,

Thanks for that will take a look.
Seems mine was just low on gas as I took it to an indy and it held the vacuum test ok so he regassed it and so far so good. I think there's possibly misleading info on the net about the aux fan, depending on what engine you have.

 

I've recently had a similar problem with heating and fan on my X5 3.0i 2003 E53. The symptoms were that the fan would stay on a constant yet very low level and intermittently work. I took it to the electricians who done a diagnosis and concluded it was the the heater motor resistor pack that controls air flow etc . It's cost me about £165 to repair. The part cost £72 labour £60 and diagnosis £35. Can anyone shed some light on this? Cheers

 

A garage will have a machine to do a regas.
R134a is the gas and you can buy a kit in halfrawds but it will cost you more than a regas and only top up the old gas.
With a regas it takes all the old stuff out and then puts the new back in with the correct amount of oil as well.
