Hi car is 2007 335i, and has been running fine, until i was joining highway and hit about 5k, engine light came on,pulled over code read 29DC cylinder injection switch-off, it was idling terrible, reset code ,and started logging idle was perfect 700psi hpfp at idle, then about 5k i get code again, pull in check log and the log is below, am thinking the Hpfp is dead, but looking for confirmation really, if i didnt have the log and kept below 5k there would be no other symptoms and youd never no,and suppose thats why i need the extra help as i thought a failing pump would have more symptoms, anyway and help would be appreciated
