    Default Tyre Pressure Sensors

    Evening all,

    Decided to check the pressure on my tyres today as they seemed a little low, and found they were around 2 bar, or 29 psi, however the tyre pressure light was never on.

    Does anyone know how far under the recommended pressure the tyres would need to be to set the warning light off?

    I'm wondering if the sensors aren't working, as when I tried resetting the DDS after putting air in, nothing seemed to happen.

    Thanks in advance.

    Pretty sure DDS just works off the wheel speed.

    If one tyre pressure is low the wheel will rotate at a different speed and the light will come on...but obviously if they're all low but around the same pressure it's not going to see anything wrong so the light won't come on.

    Its only the TPMS system that actually checks the tyre pressure system.

    Ah OK, so there's not actually a "sensor" as such.

    Makes sense. All the tyres were around the same pressure.
