The OP wil need to replace the tire as he has driven on it with extremely low pressure - however - an owner with TPMS gets an alert, tests the pressure and sees 25psi. The owner pumps it up to the proper pressure and drives to a tire shop where a nail is found and the tire patched.
Most BMW dealers won't patch a tire because they don't know how long the tire was used with low pressure (or how low the pressure actually got) but most tire places will.
It is perfectly safe to do assuming you know that the tire was never driven severely low.

Of course I patched my RFT
given how expensive these tires are and to do my little part in helping the environment by producing one less scrap tire
any shop other then BMW will happily do it for you and in most case free of charge.
You are absolutely right in the sense that it is ok to patch a RFT given it have not been driven a long time with no air pressure but the problem is this is a personal judgement of the driver as you can't really see the state of the RFT, but I rarely drives in autobahn speed so no harm in patching it.
Most BMW dealer or service center will not patch the tire because of liability issues as they don't want someone suing them after they got into an accident, so they just recommend you to change it and if the tire fail, they can always sue the tire company
For those who don't have the luxury of a government mandated TPMS, just ditch the run flats if you don't need it, is so convenient for us to call a tow truck and they wouldn't charge you an arm and a leg for towing it to the nearest tire shop.
