It is not a tire pressure monitor system.
Correct - I should not have referred to it as such.
It indirectly detects pressure loss by measuring a higher wheel speed at the wheel which has the puncture.
My wife's Renault has the pressure sensors on each wheel. But I wonder if this just introduces more risk (when getting tyres changed/replaced), or potential points of failure.
Does the BMW system not use info from the existing ABS system/sensors?

You are correct, the ABS wheel speed sensors are used to detect the flat

Where is this info from ?
It sounds strange, since they have just switched all models to the non-pressure system

No, it does not tell you which tyre it thinks has a problem. Which is nasty.
Mine has gone off three times in 10 days. The first time was a real puncture (on the day I picked the car up - dealer fitted a new tyre to replace). The second time it went off I took it to a tyre place, they said one tyre was 2lb down, but found no puncture (but did not take the tyre of the rim, just did an external inspection). I reset the monitor and its gone off again five days later. Checked all four tyre pressures, they're OK - to within a couple of pounds of each other in pairs. Reset monitor again. If this carries on I shall get a bit grumpy! Anyone else with over-keen TPM?

Can you view your tire pressure through idrive at any time?
