2009 135i engine question

If the CEL is in the middle it's something like complete loss of oil pressure which would require you to stop immediately. The other CEL could be a faulty sensor which wouldn't require you to stop driving right away.

But, I would bring it in ASAP.

Update: I just got my car back after four days at the dealership (and because they ran out of BMW loaners, my courtesy car was a big red Dodge Charger!!). Anyway, they believe that they have found the problem through the process of elimination and many long road tests. It wasn't the HPFP after all, but #1 fuel injector. It's now been replaced and I have my car back and she seems to be running great again. I've already had her on the freeway without incident, so I think everything may be back to great in the 135i-land that I inhabit.
Again, thanks to all who contributed their ideas to help figure this out!

Good to hear it's fixed and let's hope for good. My dealership always runs out of BMWs so I've had the displeasure of driving a Jetta and a Suzuki SX4.
