My son’s Mazda 6 failed its Mot yesterday for an SRS (ie airbags etc) warning and a braking one. Amazingly the main dealer (who didn’t do the MoT) accepted a booking for today and resolved these faults. The service desk says it was slightly low brake fluid and that set off the brake warning and that the SRS one was not live but due to a previous code saved by the system and representing when the brake one came up,

Maybe he or the receptionist have the wrong end of the stick but it sounds unlikely to me. Has anyone come across this?
