My tyre pressure monitor light came on this morning, telling me to reset pressures and showing all 4 tyres red. I'll check pressures tomorrow, but any idea why all 4 would show up at once?
Well it could just be that all four tyres are under pressure, in which case they will show up if your display does indeed show all four individual tyres. On our Hyundai i10, the TPMS light comes on if it detects low pressure but doesn't tell you which tyre so it forces you to check all four tyres until you find the one that is low on pressure.
As a note, 3 years or so ago, I bought a brand new pre-reg 500 from a Fiat dealership and I had to inflate all four tyres myself on their forecourt because they couldn't be arsed to do some simple basic checks before I started my journey back up North. That particular 500 TA wasn't fitted with TPMS, I only noticed because both front tyres looked well under pressure before I even got into the car. When I put the pressure monitor on, both front tyres were down to 10 psi.....:bang: A pretty crap state of affairs when you've just parted with hard earned cash and the dealership clearly didn't even bother to PDI the car properly.
The TPMS goes off on my car when I swap between winter and summer wheels, not straightaway but usually a day or two after. I always check the pressure again, even though I checked them when I put them on and once I reset the TPMS it's fine.
I see you've just got the car, has it had any new tyres?

Personally I think the above is a crap system, fitted because all new cars must have it so its the cheapest option, problem is its way less accurate rather than 3Lb down its more like 10 until it trips, just think what a 100 miles at 70 would do if your tyre was down nearly a third?
