One issue with runflats is they are internally damaged by driving on them while deflated, and this damage is not always visible even when removing the tire from the wheel for inspection.

If you have driven on a deflated runflat tire for any distance it's a good idea to replace it. Also, buying used ROF tires is a bad idea because you never know their history.

My 535d had 3/4 original ROF tires in unsafe condition which was not visible without putting the car in the air, the inner sidewalls were deteriorating. These were the 20" Bridgestones. I'm not sure if they were run at low pressure (I bought the car used uncertified) or if is just how they wear over time.

OP, you may be ok if the tire still had some air pressure when you arrived to get it fixed, and hopefully the shop took this into account before fixing the tire.
