Is a TPMS fault likely to be expensive to fix?

A few days ago the tyre pressure warning dislayed a malfunction sign. The following day it appeared to be working and was able to display the tyre pressures. The next day the malfunction sign reappeared.
Is there a straightforward fix or is it one for a) a main dealer or b) my regular BMW specilaist garage? Is it likely to be an expensive fix?

The most likely cause of this is a faulty TPMS sensor, which are relatively inexpensive to replace but if you plan on doing this yourself it would be sensible to check if this is the cause before ordering replacements. A diagnostic scan should result in a fault code if the sensors are to blame, but you may wish to take it straight to your independent BMW specialist who can likely resolve the fault quickly and at a reasonable cost.
