Can anyone inform if there is a separate Tyre Pressure Monitoring Programme for BMW X3's with run flat tyres?
Previous to having work done (unrelated fuel tank replacement) at a BMW dealer the tyre pressure indicator would alert on detecting a drop of a few lb's and instruct to drive to the nearest dealer. After the work, my tyre pressure sensors were not functioning at all (had a puncture and car didn't know) more work at BMW to correct the issue. To test I let some air out and after a few miles the display instructed to pull over immediately.
BMW told me they have loaded the latest tyre pressure monitor programme and it's the only one they have, but it looks to me like they would need two, one for standard tyres and one for run flats as run flats circumference don't change much with pressure changes. Also the new dashboard message does not correlate with a car on run flats.
