MINI Cooper S stalling problems

Filed Jan 7, 2025 · Electrical, Engine · CT

Car stalls while driving and will not start again. No codes thrown. Found relay K96 on Junction Box Electronics module to have cracked through-hole solder joints resulting in bad continuity. Relay K96 supplies power to the low pressure fuel pump in the tank, thus with bad continuity, the pump gets no power. Relay K96 P/N is NEC Philippines P/N EP2F-B3G1ST. This issue has happened to many other people with the same car that I know. I suspect heat cycles over time stressed and fatigued the solder joints, causing the joint to crack. Overall the circuit board layout needs a heat sink for the relay to alleviate the heat produced from operation. I am IPC certified and work with aircraft engine electronics regularly and have seen similar issues.

During a rain shower, drove at about 15mph into roughly 4" of water gathered on the shoulder of an access road adjacent to the highway and the engine stalled. Would not restart. Puddle of water was not high enough to breach the cabin - running boards were still above water and the curb adjacent to the street was not submerged. Car would not start and transmission locked up. Bmw roadside assistance contacted and advised not to start; tow truck had difficulty loading onto the flatbed because the electrical system had malfunctioned in the electric convertible top and was overriding the ability to put the car into neutral.
