I dont believe its the ethanol content, but thats a whole different discussion. Point being, he is right though, failing fuel pumps have plagued the N54 motors since they were first delivered to customers. Some people's last 40-50-60k no problems, others it a just a few hundred miles. You should feel a bit better performancce now that it gets replaced as well. Congrats on the car BTW, otheer than this issue, your gonna love it

nope, people try to pinpoint it to a certain brand of gas and nothing is consistant, certain mods/mileage,, nothing. i bought my car w/48k miles, dealer says it was replaced @ 44k, i have been tuned and driving/pushing harder and harder for 30k miles now and sign of malfunction yet.. other cant go a week. something tells me its another part of the systme overstressing it, not just the pump

So I've had my car back now for a few days with a new fuel pump and must say, it feels faster than ever. I've let some fellow driver friends of mine take it for a spin and I the acceleration is a lot more pronounce.

Maybe it's all mental, but the far feels smoother and faster. One thing to note though, I've never met with my "service advisor" and they never told me precisely why they changed the fuel pump. They just did it, and didn't even bother to upsell anything.

Kinda strange for a dealership to not want to rip off a customer, but then again, my "service advisor" might be stationed in some other country. Or office. Or desk. Whatever. I got myself a new fuel pump, some new brakes and rotors, and an oil change. Now, I await an unforeseen problem in the future with regards to the fuel pump.

well here in the US all owners got a letter stating the pump is covered under warranty for up to 10 years/100,000 miles. So if they see you are having a problem most good dealerships will replace it on the spot.
