Why do I keep getting a tyre pressure warning?

The tyre pressure warning came up on my Audi A3. I had it checked by a tyre fitter and they found no need to pump them up and reset the alarm. This happened a few more annoying times and it became quite frightening especially when driving on to a motorway.

On changing the A3 for an 18 plate Q2 Audi Sport wheels, it started again, this time the rear off side. Second time the car went to an Audi main dealer and I was handed the technician's report with video. No charge and off I went.

It has since come on again. Do I need a new wheel ? Are alloy wheels porous?

Has the tyre actually lost pressure when you have it checked? If it has then it is likely the wheel has been damaged – though it's probably not porous on such a new car. If the tyre is at the correct pressure something has likely triggered the sensor, you may have hit a big bump or pot hole, although you should be able to reset the sensors. If that doesn't work, there's likely something wrong with the sensor.
