My Jazz triggered a tyre deflation warning. Checked 4 tyre pressures - all were within 0.5psi of what they should be. Reset the warning. Drove about 50 miles at max 60mph. Deflation warning triggered again.
Rechecked all 4 tyres (when tyres had cooled) with same digital pressure gauge, and all were exactly the same as they were two days previously. Reset it again
I did have a sticky brake calliper replaced earlier in the year, but have since regularly checked that none of the wheels is getting hot.
Plus - before the calliper was replaced and the wheel got hot, the hot wheel did NOT trigger the deflation warning. (That makes sense actually, because the tyre circumference would have IN-creased slightly with the IN-creased pressure, and the Jazz manual specifically says it senses a reduction in tyre pressure, not an increase)
