I will adjust the pressures and have a look and see what calibration is needed on that system.

If you have no time to look at the label on the B pillar and to check your tyre pressures you should not be driving a car at all.

Fair point M'Lud. Although in my defence the sticker is so low to the ground my knees couldn't handle it, the OSD has given constant readings every day for 4 months and i wrongly assumed the pressures were correct from the start.

Green caps - had my dealer not pointed this out to me I would have not known. So where would one buy nitrogen?.
So when is this โ€˜old enough to know betterโ€™ supposed to kick in ?

Try ATSEuromaster. Although their branch finder doesn't work for me.

I put 2.3/2.5 into them this morning. The car display read 2.4/2.5. On normal driving this increased to 2.5/2.6. The fill level showed +0.2 all round when set to 21" Summer.
It doesn't quite add up but close enough I presume. I hope I haven't damaged the tyres too much running so low for so long.

The listed pressures are for 'cold' (i.e not driven on) tyres at 20ยฐC. Unless there was something of a heat wave when you topped up, the sensors expect the pressures to be a bit lower at our current ambient temperatures, hence are saying that they are now a little bit high. But close enough, as you say.

EDIT: Roughly 7ยฐC change in temperature equates to 0.1 bar, hence if you topped up at 6ยฐC, that explains the discrepancy.

I phoned around my local Tyre dealers and ATS were happy to top up the Nitrogen (No charge) wouldnโ€™t even accept a charity donation.

According to my OPC Nitrogen gives the Tyre a solid shape and better ride..
