1) Top up coolant to max and NOT more on a cold engine because doing so will created leaks through the reservoir joints.

Well said accept this point. Nothing should cause leaking through the reservoir joints!

1) Top up coolant to max and NOT more on a cold engine because doing so will created leaks through the reservoir joints. Trapped air expands more than liquid and it’s pushed out. Initially, I thought mine was leaking. I wiped off the dried off coolant, corrected the levels and it never leaked again.

I think what you ran into was the ventilated cap releasing due to over pressure of the system, this is a safety device on all engines. If I remember BMW uses an about 2bar cap regulator. Meaning if you overfill or pressure builds up it is allowed to escape already.

Totally agree with your HVAC observations, mine is a 2023 and has been getting better all the time, I would say it is now 'normal'
Trickle charger is another thing I do every now and then, same reason
Never looked at steering reservoir, don't get any squealing and it work fine for me

I think these things work, they just need time to settle in and the users to work out the kinks. I think they nailed the old Defender

Well I guess it’s gives it character and character we all know will increase in value in years to come.

I wish I can afford it like a company called Twisted buy hundreds of old Ineos, leave it in storage and 10 years later bring them back out, modify with fancy leather seats and uprated engines and sell for a fortune.

Ineos just needs to unlock it and make parts widely available. It’s all the do with contracts and business. I bet Ineos signed a contract with Bosch saying they can’t unlock it for the first five years or some kind of threshold. Otherwise how can they validate the warranty if you don’t have it serviced at dealers. It’s all business I guess. With such a low volume, if we all got our Ineos serviced at an independent or ourselves there would be no dealers left.

With the steering, I do believe they did make it like this from a legal standpoint and make the user modify and discover the fixes. If the steering drove light and accurate like a modern SUV, it would definitely fail the moose test.

You are right but it has done previously on this forum. Maybe a bad batch I don’t know. I mean why design a pressurised reservoir with a welded joint running across the middle.

who do you use for servicing?

who do you use for servicing?

Dentons. Or is usually fix small things myself. I rarely go, it’s a 1 and half hour drive there and 1 and half hour back.

I use Chester, thankfully only 30 mins

Agree it does but somehow it has leaked through the welded joints on some reservoirs.

mine did that and they were replaced under warranty, HVAC improved again after that

2024MY Either front or rear vent has heat. Never both. And the unit make vibration sound daily. Dealer have difficult replicate these issue while truck in the shop..

How far is your dealer.
Can you arrange to deliver at a time that they will immediately send a technician (mechanic) out on your arrival so that your truck is operating as you explained. I did this in the early days of problems and dealers not really being aware.

T levels is your coolant at on cold engine ?

 

[Sammyd]

How frequent is this purging , refilling coolant business which many speak of?
Is this in perpetuity? Special coolant from dealership?

Purging when necessary when it doesn’t work properly. Ie not blowing, not getting hot, not getting cold, blowing both hot and cold.

I would say more frequent on the first two years. Check levels every quarter and top up level to max if necessary. Check levels on a cold engine, with bonnet/hood fully propped up in service mode. Google BMW green H12 for the nearest supplier. Purging process is on the forum, just do a search.

I thought this had to do with faulty valves and sensors in the hvac.
Is this just a problem with “air” in the system or faulty hardware and software?
Purging will not help with the latter.

Trapped air from poor design limitations and software. But if you have a newer model, it should have been already updated. If you live close to the dealer get them check and do it.
