You're relatively new here but of the five people I know who own(ed) N54 powered cars, every single one had at least one HPFP replaced. One of them had four replaced, one had three, and my coworker is on his third as well. The issue may have been resolved but for a good couple of years, HPFP failures were sadly the norm.

How does the 120,000 mile warranty help you when you're stuck on the side of the highway? This happened to many people. Mine gave up as I was pulling onto my street... the day I was supposed to take it on vacation... on my birthday. That is not "reliable" by any stretch of the imagination.

preventative maintenance

they issued a full recall on all effected HPFP's

if yours happened before the recall, well... bad luck in that case, you were an early adopter.

Preventative maintenance on a car with 6k miles on the clock? Give me a break...

Early adopter? The engine had been around since 2007 and my car was a 2010, the last year of the N54 in the 1er.

im with king on this one, from 07-10 hpfps were an absolute problem, this was not a rare or unusual occurance. mine was replaced at 24k in 2010 and i consider myself lucky. LOTS of people had to go through 2+ pumps. It does appear that the revised pump holds up though, you certainly dont hear about it as often.

My recently purchased ...CPO 2010 went in today, after 3 mornings of cold start issues (Engine warning, struggling to idle and loss of power).

Their initial diagnosis is a misfire on cylinder 1, but the problem disappears when engine warms up. So they're keeping it over night for retest in the morning.

So I'm going with unreliable...

did you get a check engine or service engine soon? And was the misfire itself noticeable, or just the symptoms (poor idle, limp mode etc). just curious...

I am a recent new owner of a 2009 135 CV 6spd manual. I am very happy so far, mine is out of warranty but I purchased a 3/36K from Zurich to give me a piece of mind. I have a few friends with N54's and all the same discussion. My only other mention would be the wastegate rattle also now under an extended BMW warranty. I recently traded my 2008 X5 (4.8i) for a 2013 X3 3.5i, so I hope to chime in and give my own impressions between the N54 and N55.

Yeah, I got check engine and symptoms. Poor idling... loss of power. I experienced a similar loss of power when one of my solenoids went on my e46 330i.

Hopefully the dealer has a definitive answer for me this morning.

I'm interested in this too. I'm currently looking at this CPO. Thoughts?
