UK & Ireland Heating system

[CRH]

Will the heating system ever be fixed properly on all vehicles. Mine is a 2023 and the heating system is eratic at best but generally doesn't do what you want when you want. Auto is useless. It has had the bleeding procedure done numerous times but it's still ineffective. Hot air at the back and cool up front on drivers side until on max heat. Turn rear vents off helps, turn side vent off helps. Or air on feat and face. Lower than max heat blows cold on feet. The random combinations are endless

As stated in earlier posts. Mine is a 2023 model has been to the dealer on many occasions for the bleeding procedure. I also noted both of the header tanks were leaking at the seams and they were replaced.
This all helped on incremental steps. When the heat starts to be less effective then there is still some air in the system that needs to be either worked out whilst driving, have many more bleeding sessions or have a pressure bleeding done.
Once ALL the air is out then you will get hot AND warm air. Mine is on over 28,000 miles and has only just managed to remove all the air and it works on all the directional options. I would recommend not burning your feet for a long time and then expect it to work on mid settings as it still registers hot so will blow cold. You need to then blow cold air full blast to cool the sensors down.

If you have a problem, you still have air in the system. Dealer can't fix as it needs to be cold for the bleeding procedure, which is on this site so you can do it yourself. It needs to.be run and then cool down to do it again.
Do not give up.

Do me a favour, in the morning before you start up the car (cold engine), check the following before going to the dealer. Check coolant (black cap), this should be level to max and NOT overfilled. The coolant (blue cap) this coolant should be filled to max. I suspect this reservoir is low and needs topping up. There is a pressure sensor inside. If low, the air con will not work and overheat resulting in the fans activating.

To check the levels, you must prop open the engine bonnet in service mode, otherwise you can’t see properly and it won’t be accurate.

If this doesn’t work then back to dealer.

Thank you for your suggestion. Here is the current situation with the reservoirs. The one with the black cap is overfilled; the level is above the maximum mark. The reservoir with the blue cap has its level between the minimum and maximum marks. Should I therefore drain a bit from the black-cap reservoir and top up the blue-cap one?

In addition to the system not cooling properly, when it does provide a small amount of cooling through the front air vents, the rear seat air vents blow very hot air. In other words, the system is not only chaotic in terms of the air temperature it delivers, but each vent is supplying air at a different temperature. The rear seat vents always blow extremely hot air.

I suspect there must be an issue with the valves that distribute air to the different outlets, since being a “single-zone” system all vents should deliver air at the same temperature.

Thanks again for your comments. Happy New Year.

I would just add to the blue one, mine are a bit over max.
When did you last have the aircon gas checked?

Never, I've had the ineos for a month.
How can I check the gas charge?

The black coolant. I would take some out. Don’t overfill otherwise it will leak out of the seams or lid when pressurised (as per your picture).

Fill the blue one to max. (Controls the air con)

Rear vent hotter then front is unfortunately normal. Many people have the same issue. Ineos probably designed it this way because the Ineos doesn’t have any rear floor vents. There is nothing wrong with the actuators. It’s software.

Try this first before going to the dealer to regas the air con and check for leaks.

Dealer needs to check this but if miles away might be cheaper to pay a local garage you trust

A lot of the major tyre retailers ( and Halfords ) have the ability to check for leaks/ recharge A/C. The trouble is checking for a leak means going through the full procedure- empty, check and recharge with gas. So that is going to be closer to £150, if nothing found. But if there is a leak it is going to be a dealer warranty job, so it will be a wasted visit and money . A lot of dealers these days don't have the facility, they just sub contract to ..er a tyre retailer or Halfords

I was thinking more of just getting a cheap re-gas and see what happens?

You can buy kits off amazon to do that, £75, I know cos I have a spare that I don't now need 🫩

nice to know, didn't realise you could re-gas the aircon at home
