Heating system is useless

[255/85]

If I have one major complaint about mine as well is that the heater is rubbish until you drive for 30 minutes at least. We have been heating cars for about 100 years so this problem is really inexplicable and clearly avoidable.

Ours has been slow to warm sometimes taking 30 minutes to really develop heat - especially when a journey began with a cold engine and a downhill run. Then we discovered that using the 2nd vent setting (face & feet) on manual resulted in much quicker warm ups. After I did the B58 coolant purge procedure things improved even more with slightly warm air blowing while still sitting in the drive. Things could still be better but it's a big cabin and a small engine. I'm not sure how much to expect. I will add that the seat heaters work almost too well.

This is true as well. Although, some respondents simply replying with 'it is a non-issue' can be seen as dismissive, however it happens in EVERY forum I have ever seen. In itself this too isn't generally a problem, because free speech and all that! Example is that my electrical systems for the most part have been behaving very well for more than 6 months now, and others still have issues. I can see that being a problem for many when such issues persist!

I had the rear door open faulty sensor alarming and annoying the crap out of me for months until the whole rear door locking mechanism was replaced.
On the other hand my steering is great and tracks straight with about 80% return to centre.
The rest seems to work as it should, but then I haven't modified anything.
So there does seem to be a lot of inconsistency and variation around the world.
Although one person's major problem is another person's quirk.

Engine size vs cabin size have nothing to do with the temperature of air coming out of the vents, right?

True but my single cab pickups don't take much output to feel like I'm in an air fryer.

There is some weird delay when switching around the settings. if I get impatient and start fiddling with the knobs and buttons too rapidly it seems to confuse the canbus/computer. Making one setting change at a time and waiting five seconds until I hear the various components move into position before making a second change seems to help.

IMO they should have just put in a basic slide adjustment for the temp like in the 70 series LC. They missed the mark on the "Basic" feeling in some aspects, and the heating and cooling is one of them. It should not be that difficult. But somehow, Ineos has missed the mark on making something simple not so simple. Personally, mine works find 90 percent of the time. Occasionally, it will get stuck in high heat mode and I have to turn it off completely to avoid roasting myself or my passengers. I have owned over 30 vehicles, and this is the first one that I have ever had issues with basic temp controls.

Many moons ago, I posted this picture. This is all we really needed or asked for!

This is the setup in our Fit/Jazz and it works perfectly.

For real. If they stuck to the true design aspect of basic is best, they would of went with this exact setup. Literally all we needed.

Seriously they should be embarrassed enough to fix this for all existing owners. What they have produced is an hvac system from a high school automotive class project. It’s pure ass

Most people are still missing the elephant in the room though
If issues like heating, cooling not working now when the cars are brand new what the hell are they going to be like as a 10 year old unit that has spent years being used as a actual 4wd touring truck and starting to wear out like all cars do

Sell before warranty expires. Treat it like the Land Rover it aspires to be

Electronic activated hvac requires more competencies in software and control system. Higher complexity bar than human operated mechanical lever moving a flap around.

Point being, they went in the wrong direction by using electric activated hvac. Should have gone old school mechanic.

I seem to recall those sliders getting stuck, hard to push and didn't work with aircon.

So Ineos would have fared worse with embracing mechanical?

Mine works fine. It has not always been the case and needed the ministrations of the dealer and multiple calls to Ineos dealer support. The details are recorded elsewhere on the forum, so I won't repeat them here.

I came from a LR110CSW with exactly the mechanical HVAC, (minus the AC), suggested above - they can suck too! The heater matrix is too small to reliably heat the volume of a 110, there is too much uninsulated sheet steel and the blower motor is a poor design.

From what I gather from various sources the primary issue with the Grenadier heater is that it is a bear to bleed the two coolant circuits and both have to be filled to close to the max for full effect. There is not a easy fix, as there is not enough vertical height to make getting the airlocks out easy, it's a packaging issue.

Knowing that the HVAC can work OK means the heat and light in this thread needs to be directed to the dealers and then to Ineos dealer support. Make sure your coolant circuits are filled to the max with the correct coolant, get any leaks chased down and top up every time the level drops.

There have been some build issues with the heater box, with jammed flaps and failed servo motors, but the diagnostics for that are wholly conventional, (remember, mine is an early build truck, so I have had longer to grind the issues down).

The switch logic is a little slow witted; adjust and let it settle for 30 seconds before adjusting again. If you are not getting what you dialled up previously, increment one dial around one click, give it 20 seconds, then set what you actually wanted - it usually gets the point and does what it is told. The system was designed to work in "Auto", moving the dials or selecting/de-selecting de-mist can cause Auto to become deselected, so if it goes cold/hot on you, check the Auto light is on. Later software builds appear to be a bit better.

To summarise, your heating system may well be useless, but others work adequately, so the issue is with your truck and your dealer. If the dealer is stupid enough to say "they all do that, sir", point them at this answer and tell them to contact Ineos dealer support or you will invoke the lemon laws, ("not of merchantable quality" in the UK).
