e63
with my car from dealer invoice. fuel pressure 3.8 bar, under hard acceleration dropped to 1.5 bar. required LS and RS fuel pumps, re and re rear seats, re and re covers for fuel pumps, new seals and torque rings. code was 3697 fuel pressure to low

hope this helps

any way to check these fuel values through OBDII with a autoenginuity tool or dashdaq?

i have a similar issue in my 63 that has happened maybe half a dozen times most always if i can remember in 1-2nd shifts with esp off....feels like ESP kicks in, bucks, hesitations, catches gear and continues at WOT...feels more like a trans issue/slipping? but who knows. never had a code thrown and it's relatively rare

No codes in my case, maybe the same for you... I would just physically check the fuel pumps out and harnesses located under the bench seat in the rear.

Well, this problem just reared it's ugly head on my car. Thank goodness I wasn't trying to turn and accelerate right to the flow of traffic in a nanosecond.

My symptoms are exactly what Craigo described. At least I can take it easy around town and figure out exactly what is going on instead of having little time to research and get the work set up to be done at a reasonable rate!

I just recently had a set of MBH long tubes installed and when I took my E63 out on the interstate and gunned it, I got the same bucking issue.
Took it back to the guys at Buckhead Imports and they checked it out and determined that all of the codes were not cleared and that there was a code for the fuel pump that needed to be cleared. Once they did that, the car is running like a champ.
Amazing how sophisticated these cars are..but when something goes wrong....it can be a real headache.
Hope you find your issue !! Good Luck.

Interesting. My car is throwing codes for the rear O2 sensor, but it has been some time that is started doing that. I am going to get with chiromikey to check codes in the coming week, so I hope to get at the bottom of this.
