Tyre Pressure icon flashing

[Mahatma]

Took my M roadster (2002 S54) for a drive after 8 weeks and not far into my journey the tyre pressure icon came on and began flashing. I did all the checks before leaving so I pulled up and checked the tyres. They were all okay, no signs of one softer than the other and to the eye all seemed equal (near brand new tyres all round). I stopped at the first service station and put in the recommended air pressure in all four tyres (front 2.4bar rear 2.6bar). Turned ignition on and icon was flashing and drove off. I returned to my garage some 30 kilometres later with icon still flashing. I have searched the internet for clues but so far not successful. Any ideas much appreciated.

Problem solved. Easy fix. A bit more digging and found the solution in the Manual specific to my car. With ignition on position 2 dash icons light up including the flashing tyre icon. Icons then go off leaving the flashing tyre icon and the red engine icon. All you do then is push the button in (image) found beneath the headlight switch and the flashing icon disappears and is re-activated. When you click it back out a steady tyre pressure icon (yellow) appears on the dash (de-activated).

Why was it flashing? Low Pressure that was resolved…?

I didn’t check the individual tyre pressures before I topped up at the service station (that I really should have) because they all looked pumped up before I left. It was one of those pressure pump stations that you set the pressure to that cuts out when set pressure reached. I will say though that each tyre took a bit of air before cutting out. I would hazard a guess that it had something to do with uneven tyre pressures and had to be reset straight after…So glad it was as easy as that in the end.
