Another question

so i’d like to reduce the tyre pressures on my Ducato 2021 build, it has the built in pressure sensor/monitors in each of the 6 wheels and when I do, say 80 psi down to 65psi, I get the dashboard low pressure indicator lights.

Does anyone know how to reset/adjust the pressure sensors so I can run at 65psi or even if it’s possible without the dash board light coming on .

thanks

Not sure Al but maybe someone familiar with the fiat Multiecuscan software could advise on whether it’s possible to reset the parameters🤷‍♂️🤷‍♂️ good luck 👍

I adjusted them on my PVC using multiecuscan software and a yellow cable. I got mine from Gendan.

aha!!

so it’s possible then it seems, is this a service you could do for payment Tim

I’ll ask Mick at SAP in the morning if he can do it

On my 2023 Ducato I am having to put up with the low tyre pressure dash warning because the alternative is running with tyre pressures way above the tyre manufactuers recomendations (in my case Continental CP tyres) that makes the ride rediculously hard and uncomfortable. My understanding from other owners is that to adjust the pressure settings in the ECU requires Fiat only equipment but they a reluctant to carry out the procedure. Unless a Funster knows different.
It's seems crazy to me that there is not an on board facility to do this like there is on most other vehicles. Also that Fiat are not aligned with either their tyre suppliers or customer safety needs.

I absolutely agree, driving at 80psi front is like having solid tyres on lol, when I had the Comanche tag with no sensors, same chassis same weight as my Rap, I ran at 62/65 and it transformed the ride.

Trouble is I can’t stand seeing dash lights on hence trying to find a solution 🤔

Sure you can Al but we never had tpm on our Fiat. I have MES but no Fiat to plug it into 😁
I do have a copy of Xentry for mercedes which does everything if you change to Merc 😁

Can you plug into my Fiat and adjust the tpm for me or are you saying you need something else

and I won’t be changing to Merc anytime soon mate 😉👍

Yeah I can plug it in an see if it's a option if Tigger-Tim has done it shouldn't be a problem but I won't see you till maybe Drax next year and I don't carry the gear with me now cause I have no use for it. Mick might be able to sort it for you if not I can at Drax.

Is that warning an MOT fail?

thanks Dave

is this something I can make use of and if so do you want to move it on mate

MES will not be able to write back any changes if the base vehicle has an SGW integrated in the BCM/ECU. There was a brief period when the SGW was a standalone module that could be bypassed with a cable/module but latest versions cannot be bypassed. The relocation of the SGW function happened around 2021/2022 on Series 8 and later versions.

can you please explain what SGW and BCM means
Secure Gateway - stops non Fiat Dealers making adjustments, like a firewall.

BCM - Body Control Module, an ECU that does the body functions like doors and windows.

Hi,

not quite just Fiat that can make adjustments - there are now independent diagnostic systems that can work properly with the Fiat gateway (for instance https://www.autel.uk/product/fca-gateway-12-month-access/) - I suspect that slowly more independent garages will need to have this sort of access to work on vehicles with SGW, so they may be able to help with changing the tyre pressure settings.

Our 2021 van has the gateway built into the BCM rather than the separate bypassable module (I went looking for the module and found the mounting point, but there is nothing there). Learned about all this trying to get a spare key made by an independent auto locksmith...

Anyway, fortunately ours doesn't have tyre pressure monitors - phew...

cheers,

Robin

no problem Dave

i’ll wait n see what Mick says this morning and if not i’ll wait till I see you at Drax 👍
I’m just about to be in this position as I’m changing tyres on my 2024 Ducato tomorrow. Very interested to find out whether there is a solution to this.

On my previous Boxer based van, I reduced the pressures to just a whisker above the warning message. Wasn't ideal but they wanted silly money to adjust the settings. On my current 2016 Ducato I run at 65/70 without any lights or warning. Whether Carthago tweaked the pressures at the build stage I've no idea. Pumping up the tyres is such a fag, I haven't reduced them further to find the warning limit.

Please come back and let us know how you get on as I'm in the same position. I take it that you are changing to van tyres from the Agilis Campers and hope to run them at sensible pressures. As you say your van is 2024 I presume that you are getting rid of effectively new tyres, bit drastic but I'm considering doing similar. What tyres are you going for?

Dropped the van off at Micks just now and they don’t have the equipment to change the TPM’s so unless someone offers to do it i’ll have to wait for Drax

Is that warning an MOT fail?

I'm not sure. But if it is, then simply increase the PSI prior to the test.

Yes it is an MOT failure, one of mine was faulty just before its 1st MOT and the hassle I had trying to have it fixed. Fiat garage changed the module but couldn’t get it to talk to the tpm, they eventually got it after 13 hours of work on it. Thankfully they only charged me 3 due to their embarrassment on not knowing how to fix a simple issue.

Al n Val I think some tyre companies may be able to help as they need to reset after changing tyres, my local one was going to do it for me but it turned out to be a faulty module instead.

Yes, I will be getting rid of the Michelin Camper tyres the van came with as I need tyres suitable for winter conditions with the 3 mountain peak & snowflake symbol.
I have decided on Continental VanContact A/S Ultra tyres as I have had very good experience with Continental Winter tyres on cars in the past. I’ve got my fingers crossed that these will be as good 🤞

This thread leads me to a question that I have:

2020 Swift Escape 674
On Fiat Ducato 2.3 base
Uplated to 3.65
Tyre pressure recommended as per plate 80psi

I’m not overly knowledgeable about tyre pressures and keep reading various posts about people ignoring them and deciding their own.

We run ours at 80psi and are not aware of any disadvantages as long as we avoid potholes. Can anyone advise if there is a better setting and why?

What are the risks/driving efficiency of lower pressures? Do the tyres wear out quicker? Can they puncture more easily? How does it affect the mpg?

All advice greatly appreciated.

Oh that’s a shame. My van is booked into SAP in December. I had my fingers crossed he could fix it.

I'll answer as best I can

when I run at 80psi the ride is like having solid rubber tyres on at the front, the sidewalls on Camper tyres are as I understand, already reinforced with steel, thinking they'll be stood around for long periods, so having them also inflated to 80psi makes them more or less solid (imo).

Deflating them to approx 62-65psi gives, once again imo, a much softer ride and stops quite a bit of banging and crashing you feel from the front end. I had the Comanche and it had done over 20k miles when i px'd it and the tyres looked like they do another 20k, never had a puncture either. MPG was imo unaffected.

On my travels today I popped into 2 local well respected tyre dealers to discuss this issue.
The first one was adamant that they would not supply van tyres to fit on a camper van, even when I pointed out that the van tyres had a higher load and speed rating. They said it was company policy. I tried saying that I wanted to change to 3 peak snowflake all season tyres which are not available in camper tyres but he wouldn't budge.
The second dealer knew of the problem, but was more sensible. He would supply any tyre I wanted but suggested that I would be daft to scrap new tyres. His suggestion was to run the Michelin Agilis CP tyres at about 55 psi for my weight of PVC, should give reasonable ride and grip. He reckoned they were plain dangerous at 80 psi. His suggestion was to find someone to alter the TPMS, or put up with the warning light and return it to 80 if Fiat needed to look at it for servicing. Or get them to disable it and buy a Tyrepal system to comply with the law.
Lots to consider!
