Let me tell you, all those folks who said limp mode is like a 128 don't know limp mode. The car stalled if I lifted below 1.8K rpm. I don't think 128s do that.
No problems prior to the freeway incident at speed. After that I parked it for the night. Next morning it took a good 7-10 seconds cranking before the engine fired. I got this little transmission symbol flashing on my cluster. Owner's manual said the transmission symbol appears on Canadian cars to indicate an emissions issue (huh?). I took it in and told them my money was on the HPFP. Turns out I was right:
PERFORMED SHORT TEST AND RECEIVED CODES 2FBF, 29F2, 29DC, 29CE, AND 30FF. LOOKED UP SIB 12 55 06 AND PROCEEDED TO FOLLOW TEST PLAN B1214 DI6KNDR TO TEST THE LOW PRESSURE FUEL SYSTEM. THE LOW PRESSURE FUEL SYSTEM WAS ABLE TO MAINTAIN MORE THAN 5 BAR AND THE PRESSURE SENSOR WAS FUNCTIONING PROPERLY. THEN PROCEEDED TO PERFORM TEST PLAN B1214 DI6KHDR TO TEST THE HIGH PRESSURE FUEL SYSTEM. THE HIGH PRESSURE FUEL PUMP WAS ONLY ABLE TO MAINTAIN FUEL PRESSURES BELOW 30 BAR ONCE FUEL PRESSURE STABILIZED. SYSTEM REQUIRES MORE PRESSURE TO OPERATE PROPERLY. TEST PLAN PROMPTED REPLACEMENT OF HIGH PRESSURE FUEL PUMP. DIAG CODE D1350 00000000 02 001. REPLACED HIGH PRESSURE FUEL PUMP AND CLEARED FAULT CODES.
Part numbers were 13-51-7-585-655 RMFD HIGH-PRESSURE, 13-53-7-582-770 ASA-BOLT, and 11-61-7-547-242 SET OF PROFILE GASKETS.
BMW/SF took care of this in 2 days, and I received 5 phone calls with updates. Great service. BMW AG needs to get its act together and replace the part with something that works....
