Peugeot Boxer - Tyre Pressure Monitoring System

[maison]

Our new motorhome is based on the Boxer chassis and has the Peugeot TPMS system installed.

As supplied by the dealer the tyre pressures are too high, giving a harsh ride.

I want to reduce them to the appropriate pressures for the axle weights but, at the time of handover, the dealer said that the TPMS would then need to be reset by a Peugeot dealer.

I thought that TPMS operated by comparing relative wheel rotation across an axle. As a tyre deflates its diameter reduces and rotational speed increases compared to the opposite wheel. If I am correct then, so long as the axle has identical pressures across it, no adjustment by a dealer would be necessary.

Can anyone throw any light on this for me?

the tpms receiver will have set parameters for over / under pressure and tyre temp. that may require resetting to the new pressures. but surely that is covered in the hand book.

2017 Peugeot boxer low tyre pressure warning lamp

Hi I reduced my tyre pressure on my Peugeot for a softer ride. As the warning light comes on I have increased the tyre pressure back to where they were but the warning light and info on the dash still shows low tyre pressure. i have looked everywhere for a reset button and then n the menu to...

Thanks for the link. It looks as if my understanding is correct.

So, following our return to home from our present trip, I can look forward to reducing the pressures by 5psi, driving for 20 minutes, then reducing by 5psi and driving for twenty minutes............until the required pressure is reached. Still worth it to save on the dentistry required to replace my fillings!

I appreciate the link. Obviously a lot of people have had the same problem.

As it says in the link.
You will only get them to go so low 78psi.
Last time I spoke to Peugeot it was around 300 quid to reset the system to your liking.

It is not possible.

Our TPMS is set, by Peugeot, at about 80psi. The correct setting for our axle weights, according to Continental Tyres, is 62 front/64 rear.

The ride at 80psi is very harsh. I have had the system checked by Peugeot who told me it is not possible to alter it. I then took it to my local independent garage who brought in a software specialist in an attempt to reset it to the appropriate pressures. He found that the control software for the TPMS is “locked” at the factory.

You have the same two choices as us.

Either accept the very harsh ride or reduce the pressures and accept the warning light and messages.

The problem with running at the lower pressures, and accepting the warning light, is that having the light illuminated at MOT is a failure. You will have to reinflate them for the test.

I carry my axle weights on a weighbridge printout, and the Continental Tyres pressure chart, in the motorhome in case we are stopped and the low pressure warning light is queried by the DVSA.

The TPMS is required by EU legislation but I don’t know why it was not made owner adjustable, like our Citroën car.
It’s a PITA but, I’m sorry, you are probably stuck with it.

Our Boxer is also 2019 model

European legislation requires the TPMS but I don’t know why they didn’t make it owner adjustable as per our Citroen car.

A Peugeot garage can adjust the “trigger” pressure. I had ours reset to a lower value. From memory it cost £65.

Is yours a 2019 model?

See my post #7 above.

Yes, 2019.

Yes, 2019.

Very strange!

We have had two Peugeot Professional garages state that they are not adjustable, (one actually tried to adjust it and asked me to pay them £130 for making the attempt). I refused to pay as they had not completed the job as promised. Peugeot U.K. HQ confirmed that the system is non-adjustable during a telephone conversation I had with them regarding the problem.

The software technician that our local garage brought in stated that this was the first time that he had been unable to unlock such a system.

I give up, and hope that some-one can recommend a garage on the U.K. mainland that is willing to look at it.

It really is an annoyance when your tooth fillings are shaken out by the over harsh ride.

 

[maison]

Interesting that I have been told that the system is non-adjustable.

ontheroadagain have had theirs adjusted at a cost of ca £65

Just Paul was quoted about £300.

What exactly is going on at Peugeot.

 

[ontheroadagain]

@Just Paul was quoted about £300.

£300 is ridiculous. It takes them 30 minutes to reset it.

Do you Peugeot, Citroen, Fiat owners not have a forum of 'expert' owners with their own diagnostics equipment and the knowledge to help with most things software related?
I'm a VW owner and have the support of a forum here in the UK with members who have more knowledge of the software in the vehicles than the dealers! Not to mention a specialist diagnostics manufacturer/supplier in the US who can answer almost every question about such things FOC to all owners of their diagnostic software.

AlfaOBD has reprogramming functions for the Boxer X290 TPMS, including setting nominal tyre pressures for front and rear axles.

There are (at least) 3 options for programming the Boxer's TPMS.

1. Peugeot's Diagbox software, Actia and S-1279 interfaces. The software can be download free as Windows VM-Ware image and Chinese clone interfaces are available on Ebay. It's a pretty complicated setup but works well and is fully 'dealer level' for all functions and covers all PSA vehicles. Any dealer who doesn't know that it can program the TPMS might be best avoided..

2. Multiecuscan connects happily to the Boxer's TPMS module if selected as a Ducato. The module's ISO code matches and it works as it should. Hanging around on the German m/h forums (as I do..) I've seen that it's what our German friends with Boxer/Relay bases use.

3. As Deneb has said, AlfaOBD includes the Boxer's TPMS. When I used it on my Ducato though I noticed though that it only changed the cold pressure reference and left the warm pressure reference unchanged. Perhaps a bug or perhaps OK, I don't know (maybe the module itself will set these once driven?). I just went back in and set them with MES as I was only testing.

£300 is ridiculous. It takes them 30 minutes to reset it.

Thank you sight of your bill.

Armed with that information I may try again, once we are allowed to move!

 

[maison]

The recent replies, above, are extremely helpful thank you.

I will speak to our local garage again as their visiting software technician did say that an update to his diagnostic software may, in the future, allow him to tweak the settings. That was well over six months ago.

 

[peterc10]

My guess is that it is the same system as is in our Ducato. We had the same problem. The driving it for a period method sometime works, but it can be a pain.

It is very easy to reset the warning levels for both hot and cold tyres with a laptop with the right cables and software. Our son had the laptop and cables but not the software. When I had my problem with the air bag ECU I paid him to buy the software for about £50 so that we could get that sorted out. And while he was at it he reset the pressure levels. Well worth it compared with what a Fiat dealer would charge.

 

[Deneb]

It may also be worth enquiring at some large reputable tyre dealers, as some of them have the dedicated TPMS programmers from Continental and other manufacturers, who make the active TPMS ECUs and wheel sensors that the vehicle manufacturers fit into their vehicles.

I'm glad to see that my comments have brought out some useful info for Peugeot, Citroen, Fiat (Ducato) owners.

I know high level software for this purpose is expensive but it can often save its cost in the long run.

 

[Vipar]

Glad I don’t have a factory fitted one. I bought a Chinese one for £20 works a treat.

If your Boxer has Michelin Agelis CP Tyres then 80 psi on the rear is correct? Michelin recommend this pressure regardless of what load you have on the rear tyres.

 

[rtj49]

If you come across a Peugeot dealer who doesn't know how to configure the TPMS using their own Diagbox kit (to be fair it is quite well hidden) then you could always give them a lesson - but negotiate a discount first!

Select vehicle type then:
'Repair > Test by ECU > Under-inflation detection > Repair > Spare part > Reading of the reference pressure of the tyres'
and 'Setting of the reference pressure of the tyres'.

Continental Tyres on ours.

I was aware of the Michelin recommendation having had them on a previous motorhome, and a very harsh ride as a result.

Are the Tyre pressure sensors in the wheels? as I understand some vehicles are based on rotation sensors? I suspect they are as now I have changed the wheels on my vehicle the warning light is on.

Yes the sensors are inside the wheel.

That won't help if the original TPMS is integral to the vehicle. If the base vehicle system is indicating a malfunction due to absence of the wheel sensors, it will be an MOT fail, no matter if a secondary system is installed.

It either needs the original sensors removing from the original wheels and fitting to the new ones, or new sensors fitting and programmed to the system.
