Used Car - Tyre Pressure Valve Fault - Am I Covered?

Agreed. But surely it can't be the TPMS? Because that's relaying that the tyre has lost pressure, which it has, as when I check with the pump it has dropped ~10PSI?

How accurate is the gauge on the pump?  In my experience, many pump gauges are inaccurate.  A proper, old-fashioned mechanical gauge is far better.  It sounds to me that you need to get the tyre and valve checked. Many tyre places will do a free check.

Probably should have worded better, the pump at the petrol station

Never trust the pump ? at the petrol station they are dropped frequently and not recalibrated .

Going a bit down the line here, multiple petrol pumps, plus a home electronic one all giving the same readings or thereabouts

Fair enough, so it looks like there's definitely a leak. A slow puncture, a bad fit on the rim or a leaking valve, none of which can be laid at the retailers door as a fit for purpose concern.

You're not going to get a TPMS valve for a "couple of quid" and if you just put a standard one on then you'll constantly get TPMS warnings on the dash.

Just to avoid some of the confusion here. What sort of TPMS system do you have? Is it the older passive system or the later active type with sensors in each valve?

If it's the former than all you do is manually check the tyres are at the correct pressure, inflate where necessary, then reset the TPMS system following the manufacturer's instructions. If the system then alerts you and the tyres haven't actually lost pressure than it's the TPMS system that is faulty. If it's the latter then your valve (or tyre) may be at fault but you won't be able to get it changed for just a few quid.

If it is anything to do with a leak, either with the tyre or valve, on either system then you've got no chance with regards your consumer rights.

TPMS valves are only a couple of quid, maybe a fiver if you run a merc or such, it is the sensor that attaches to the valve that is expensive.

It just comes up on the dash to say tyre pressure low. Doesn't specify which tyre, and I then just fill up and reset on the dash by holding 'ok' on the reset screen etc. etc.
