Two fuel pressure related fault codes

[Johto]

Hi!

Read fault codes from my F80 and there was two fuel pressure related fault codes:

11A401 High-pressure fuel injection upon release: too low pressure

11B401 High-pressure fuel at or after the release of injection (second environmental condition set by time delay)

Cleared the codes and drove a little and the codes came back.

There is no noticeable symptoms while driving so just the fault codes at the moment at least. Because my F80 is still under BMW warranty i visited the dealer and asked should they read the codes and see if we should react to them somehow. But dealers opinion was that if there is no noticeable symptoms and if the check engine light doesn't show up we should do nothing, just wait (when it goes boom )

What it could be. Fuel pump slowly coming to it's end? Bad injector? Has there been common problems in S55 with fueling components? Should i be concerned? Or should i just take it easy and wait? The car is at 25000 miles / 40000 km.

I know this was a while ago, but what was the outcome? I noticed the same two fault codes in my log but no CEL. Would love to know if you ever figured out the issue?

Anyone ever figure this out?

Any info on this

I just got both of these today after flashing my Flex tune. Was running perfectly before that on a full E85 tune. I'm guessing it's the fuel pump taking a dirt nap? Anyone know?

Well to close the loop on this, for me it was replacing:
