2011 M56X here 148k currently With a Fuel pump crapping out. The M56 has had its timing chain recall done back in 17 well yesterday car was bucking on accerlation like it hit a wall or a Fuel Cut Off. Car went into limp mode as I got home and parked it car cut off . Was struggling to Start for 20 mins . Pulled the Codes with my Scanner P0090 and P0087 20 minutes Later Car started up normal but the codes remain . Will not be driving it till it has been checked out . Have any owners dealt with this ?

Don't drive it again
Don't start out again
Get it towed to your mechanic asap
Take it to a mechanic you trust and get it replaced now.

I liked on eBay the other day cuz I'm concerned about this issue and I saw the pump on there for under $900 which is way better than the $2000 that the dealer wanted.

Good luck
Andy

Agreed . might auction it off we will see had a P0014 code first but I cleared it then engine was was flashing then went Away . 20 minutes later being almost home that’s when that s*** went crazy

The high pressure fuel pump sounds like it's why quite a few people are having catastrophic engine failure.

I would think that you should be good after that gets replaced.

Let us know what's going on with this issue.

Good luck

Roger that .mainly the lifter underneath cracks

were there any noticeable symptoms before it died?

Every now and then after driving it for a while and it sits if I start it up it would bog down and die and I’d start it up give it some gas and she was fine afterwards . She went into limp mode and I parked her in front of my house where she sputtered and died . After 20 minutes she started up normally for the most part but the fuel sensor code still exist . I have videos

Does anyone have the high pressure fuel pump part number? I'm hesitant to buy one off of ebay without confirmation of the part number. I appreciate it!
