Cannot find the exact parts number but got a match apart from last two digits.

Here's the link to Continental TPMS parts catalogue.


The photo from CountyV8 shows part number: A2C82208304 for the unit.
The link to the closest part number A2C8220830480 is on pg 14 of the catalogue, at the bottom. So just last two digits adrift.

Presume CountyV8 that's a shot of your TPMS and not one taken at previous demo car?
Yes shot my my vehicle the one in this post is of a wheel display at the Game Fair last year.

Is it on its own circuit? If it bongs maybe pull the fuse and keep an eye on things like the old days. Not ideal but hey, one less thing nagging at you.

That’s a good point I’m picking up a second spare wheel and tyre next week along with other spare parts and never thought to ask for another TPMS for the spare wheel. I’ll let you all know what I get 👍🏼

I've heard some service items might be on short supply, what's on your full list?

Full set of Brake pads , spring kit for front and rear brake pads , full filter set , wiper blades.
further than that I want to get a comprehensive fuse set but not at main dealer prices so waiting to gather info from the forum on what make and size of fuses required. Other than that I’ll take oils /fluids and bodge fix items like gaffer tape, PTFE, liquid weld , screws , nuts n bolts, cable ties, soft wire etc. And been recommended to get a comprehensive electrical repair kit inc connectors and shrink tube and of course all tools required.

Does anybody know how the tyre pressure monitoring works in the Grenadier?
As far as I know there are two systems on the market.
  1. the simple "passive" version which diagnoses the wheel rotations via the ABS sensors. Pro: cheap. Contra: not 100% exact measurements/ no warning when the pressure goes down in all four tyres
  2. the "active" pressure sensor in the valve cap. Pro: accurate! Contra: Price/extra technique built in/ additional efforts (time and money) when changing tyres.
There have been pictures from the central display with three digit pressure details for each wheel including the temperature as well. I guess that this is so exact that there has to be either a small DaveB or an active sensor built in.

Any comments?
This is an EXCELLENT & critical question. My LR has the TMPS, and I'll share my excruciatingly terrible experience with those little buggers... The issue starts with the reality that my LR goes through tires quickly, and a local shop I used for replacing them forgot to look at the TMPS when the tire was off. TMPS apparently can get sticky on older rims, as mine were, and makes replacing the TMPS more work. If you ask for new tires, that's all some shops will do. It's lazy for sure, but it happened. When the rubber TMPS finally gave out (they are not metal), the tire deflated almost instantly. I learned all about the "circle of death" or whatever tire folks call it. It was terrible, and I asked about alternatives. Older high end cars - like old BMWs - apparently had metal tire pressure monitors, but they were placed differently. In my case, the failure in that TMPS resulted in a cascade that stopped the LR, so if there's a way around TMPS, I would ask. The solution I got was to replace all TMPS with each tire change, but that's an expensive fix to a problem I shouldn't have. It would be better if TMPS were designed to fail in a way that didn't also jeopardize the tire they were attached to. The cracked rubber on the TMPS is how the air in the tire escaped. It's because a piece of that TMPS is both inside and outside of the rim that air can escape. Because TMPS are rubber, eventually the sun & cold get to those things and they break. Ideally, you would think something attached to the inside of the rim would have been a better design. The greedy reality is that if the TMPS manufacturer did that, they would sell fewer TMPS. As it is now, there's likely boatload of TMPS being thrown out as tires are replaced, and some of those surely have life left in them. The problem being who wants to risk using a TMPS until it breaks? If a local garage could affix a tire pressure monitor to the inerterior of the rim, it would be one and done, and the TMPS company wouldn't be making as much money on replacement sales. Certainly this is one of those areas where companies could do better if they wanted to, and the trick is to see if anyone else has done so.

Thank you for the photo. Maybe the car has another sensor in each corner to distinguish which TPMS sensor is in which corner, I'm hypothesising.
Did you use the spare at all, and if so any bing/bongs/mssgs about that TPMS sensor?
The ‘corner sensor’ set up is what I have heard about with other cars as well.

I am planning an offroad trailer with the same INEOS steel wheels and BT goodrich tires.

Regardless of whether it makes sense or not I would be interest in:
a) Where can I order the 4 wheels as a replacement?
b) Do they have the tire pressure sensor already installed?
c) Does anyone have an idea how to pair them with the grenadier cockpit? It would be cool to See them all

My list has hoses, serpentine belt, oil and fuel filters, air filters, wheel bearings, spec for oils - diffs, transfer case etc. Hopefully all the things that if goes wrong in the middle of nowhere can be fixed to get me home...

Just a thought @Telliottaus : You may find that the front & rear wheel bearings are not easily replaceable i.e. require a decent workshop press to remove them from the hubs....

Yes, spoke with the Ineos aftersales lead yesterday. That said, while not being able to repair on the side of the road having a part would speed up turn around if I can find a station or similar with a press...

You have to purchase the sensors separately. I assume the work like others being they auto detect after a short distance.

I’ve just picked these brake pads up from the dealers ready for my travels
could someone please put this in resources section if useful please
With the box open and Brembo part no visible should be able to get cheaper at a motor factors.
you do not need to purchase a spring kit separately as I was sold as all is in the kit 👍🏼

Bloody expensive 😳. Hopefully as we all buy parts and spares we can get part numbers and help each other out to buy cheaper elsewhere
Front brake pad kit £239.74 + VAT
Rear brake pad kit £141.79 + VAT
OUCH 😳
plus engine oil filter £18.45 + VAT
don’t know whether stock or ordered in

Ooff... that's the sort of money I was paying for specialist motorsports pads a few years ago.

It's a long way off the @ £40 a set for the old Defender.

But the Grenadier does stop well with them (in case the negative police are watching 👀)

Hello there - did Ineos respond with the corresponding part number for the Continental TPMS?

I have sent Ineos an email myself today requesting the same information.

Anyone else out there have the actual TPMS part number(s)?

And is it possible to disable the TPMS entirely incase tyres are fitted without the correct sensor?

Danke

This is the tyre pressure and temp sensor part number GRA-4E00-019540
