TPMS multiple warnings.

Anyone else suffered from this?

Had a TPMS status warning a couple of days ago on the way to work. Rear offside showing amber.

Have an airline at work so inflated all the tyres to the “eco” pressure on the sticker in the doorsill for the wheel size I have.

Reset the TPMS and let it do its thing.

All is fine until yesterday morning and on the way to work (60mph dual carriageway) has a TPMS warning again. This time all 4 tyres showing the amber warning. Nothing felt untoward so I got to work, checked the pressures (fine) and reset the system. Drive home was fine.

Got in car this morning and at almost exactly the same point on the journey I get the TPMS warning again for all four wheels???

I haven’t had time to check but I bet the pressures are fine.

Have I done anything wrong? The tyres were inflated originally when they were cold but I only had a short drive from airline to car park which may have not reset the system properly. I reset the system yesterday just before my drive home meaning it had a good five mins of driving to go “green”.

Could my TPMS system be at fault? Software? Or am I doing the whole inflation and resetting wrong?

Anyone else had this?? Any advice???

I had the same issue with my XC60 with the TPMS into each wheel valve (my new XC60 doesn't have that system, it works via a different method); but I found it was the very cold frosty mornings that set of the TPMS trigger.

So whilst you checked out or reset at work, when the tyres were 'warm' of course when the temperature drops, for example a freezing or frosty morning, the pressures in the tyres have dropped and hence the warning.

I resolved by setting the pressures on a cold and frosty morning and never had the warning again. I did in fairness adjust tyre pressures and reset when the warmer weather of spring came.

TPMS can take a while to sort itself out. I have to drive about 6 miles to get mine to confim it's done. I think it is related to distance no time because it is reliant on the ABS sensors to count the wheel revolutions.

I have had this once, after having rear tyres changed and all 4 pressures checked and adjusted and calibrating TPMS, the next day the TPMS warning came on and all 4 showed amber, I checked them and all were still spot on so recalibrated TPMS again and it has been ok ever since, like above post it takes mine about 6 miles or so to calibrate with mixed road driving.

Deleted duplicated post.
(Why is there not a delete option on here without having to type something in) or is there.

Thanks all. I was 90% sure it was to do with temps and weather. I’ll check them first thing tomorrow morning before driving to work and reset them.

My (older) V60 did this last year. The calibration is better, I think, if you can get a mixture of low and moderate speed driving and some tight turns before hitting a motorway.

Both tpms systems have their quirks on all brands of cars now and again. It is becoming a standard feature on all cars, so I expect an increasing number of issues cropping up in forums over the next year or two

Since November 2012 all new models of cars sold in the EU had to have a TPMS fitted. This was broadened out in November 2014 to include every new passenger vehicle being required to have a TPMS before being sold.

In the UK on 1 January 2015, legislation came into force stating that for these vehicles, an inoperative or faulty TPMS sensor would result in an MOT failure.

Some manufacturers use a sensor in the tyre that sends a signal to a monitor in the car. I think Volvo discarded that method a couple of years ago in favour of a system by monitoring individual wheel rotational speeds and other signals available through the wheel speed sensors of ABS/ESC systems
