Running flat sensor

[mickx]

I have recently driven from the south coast of the UK to Inverness in the highlands of Scotland - 613 miles each way.

Was ga reat drive and still in my first six months of owning my 2005 X5 I am amazed at the comfort and ease of driving for 10 hours in the car.

However, on two occasions the running flat sensor light up and on both occasions the tyres and pressure were OK.

On the return trip - and to date - the sensor did not activated.

Any experiance within this group on how reliable or under/over sensitive the running flat sensor can be?

Thanks in advance
