I worked in "fixing" engineering issues and you are right, not every known issue gets fixed. BMW must have calced that not doing anything is the most cost effective solution. B58 hub is different... (well partially because it is at the back of the engine and has to take all the TQ), but don't want to be stuck with a VANOS or chain guide bill haha. |
Yeah I heard that the ECU and crank position sensor was sensitive enough to save the motor, and if you had a hub fix and it spun it would take the whole motor. But if a stock hub spins it can still take the motor out since the ECU and crank position sensor doesn't retard timing in time for all cases, then piston meets valve.
