Tyre Pressure Monitor

Have a warning light showing tyre pressure osf front tyre low pressure.  Checked all pressures all ok.  Driven some miles and light wont go off. Manual says nothing about reset only that the dust caps do the monitoring. Take them off but no change.

Any suggestions?

gef - I see like me have a 2019 model.  Do you know at what pressure the TPMS triggers on the front tyres?  I have dropped my front pressures from 5.0 bar to 4.0 bar and it hasn't triggered yet.  4.0 bar is 58 psi.  I want to get it lower than this.  Presumably, you have experience of clearing the warning light.  In your experience will inflating the front tyre to say 5.1 bar do the trick and how quickly does it clear?

I have set mine now to exactly what it says on plate , probably need to drive out to check it. Dash still shows fault. 

I would not worry about it but Mot expires end of month and tax at same time.

Notwithstanding Cymro's experience I understand that re-inflating and then driving for a fair distance does the trick but I have no experience of it.  If I continue dropping my front tyre pressures to get them closer to the ETRTO/Continental recommended level I expect I will find out.  Of course your 2015 model may not be the same as my 2019 model in this respect.  I am hoping gef will cast more light on this.

Thanks gef.  So it clears without actually taking it on the road.  Does the engine have to be running or is having the ignition on enough?

None of my three not so local Peugeot Boxer dealerships will do it as Auto-Sleepers, unlike for example Bailey, hasn't fitted a new Stage 2 conformity tyre pressure label on the passenger door pillar indicating different front tyre pressures to the current and ridiculous 5.0 bar front on Peugeot's Stage 1 label. Peugeot had no way of knowing what the front axle mass of the converted vehicle would be and therefore its tyre pressure so the Stage 1 label is useless.

Have you been able to get your TPMS trigger point adjusted?

They usually have a movement sensor so they shut down when the wheel is not rotating to save battery power. Thought you might find that putting air in the tyre might cause enough vibration to wake the sensor and start It transmitting.

Thanks

is it possible that the sensor battery drains more quickly when the TPMS is triggered?

Spoke to a MOT tester i know, TPMS is checked from 2014/2015 onwards. Sensors apparently last about 5 years.  Can buy replacements and clone the serial numbers or re-programme vehicle to new one.

ATS and National tyres offer a check and repair service, I am doing the rounds tomorrow will report back.

I will only replace the 1 but no doubt the others will follow, and every 5 years!

I've read on another forum that latest AS van conversions are not fitted with tpms.

A member on this forum in another thread reported that his new PVC didn't have one which surprised me and him.  A-S currently show a TPMS as part of the base vehicle spec on their website for the Nuevo and Broadway but not any of their other models.  I don't know if this is significant.  Jef has a 2019 PVC and clearly has it.  TPMSs are a good thing providing they are adjusted to trigger at the right pressure which mine and many others are not because A-S hasn't bothered to have it adjusted by Peugeot to match the correct pressures for the converted vehicle's front axle mass.

Acording to my Autosleeper handbook..(page 8- 1) refers to Maximum Technically Permissible Laden Mass.............is unaffected by the Autosleeper conversion. from this it seems to follow that manufactures tyre pressures therefore unaffected?


Got mine booked in anyway for "TPMS" check next week

Just another thought, when the tyres need to be changed, at the high pressures steel valve inserts are recommended, but which ones to use as the tpms attached to the valve may not fit the new valve, or are they standard to fit ant tpms?

The Peugeot Stage 1 tyre pressure label for the unconverted vehicle and the Peugeot handbook states that the pressures shown are fully laden pressures.  If fully laden means a front axle mass of 1850 kg which is its MTPLM, I can guarantee you are no where near that mass.  The NCC which is the UK motorhome trade organisation states: all vehicles are plated with the tyre pressure for the maximum load that the vehicle can carry and it will be the drivers’ responsibility to vary this pressure if they wish to use the vehicle in an unloaded condition. The DVSA states: the tyre manufacturer is best placed to suggest what pressures are acceptable and these should not be exceeded unless on specific advice from them.  When I measure the front axle mass of my fully loaded Nuevo EK it is always less than 1425 kg - in fact significantly less - and for this mass Continental using ETRTO figures recommends my front tyres should be inflated to 3.0 bar and most definitely not 5.0 bar.  Because of the way the converted vehicle has been designed, as it is progressively loaded the rear axle MTPLM of 2000 kg will always be reached first.  So if the converted vehicle is loaded to its MTPLM of 3500 kg, the front axle mass can't be more than 1500 kg.  Continental using ETRTO figures recommends 3.2 bar when the front axle mass is 1500 kg.  

Richard G - I deliberately triggered my TPMS yesterday.  After a couple of miles the amber warning light (tyre symbol with an exclamation mark) came on and flashed and there was an audible alarm.  Whilst it flashed information scrolled on the panel between the speedo and tacho showing low pressure front right 60.9 psi low pressure front left 60.9 psi.  After a while the information stopped scrolling and the amber warning light stopped flashing but stayed on.  Later when I turned off the engine and restarted the scrolling message came back on showing low pressures of 62.4 psi right and left.  At the end of the journey I inflated the front tyres to 5.1 bar.  The TPMS didn't clear on the drive but it did when I took the motorhome around the block.  I will now deflate the front tyres to 4.5 bar which I know doesn't trigger the TPMS but the pressure is still a lot higher than it should be.  In your case, if you didn't get any low pressure scrolling message and the warning light simply stayed on, it probably indicates a TPMS malfunction which as you say is probably a sensor battery.
