I am crossing my fingers on the Z4 35i. I've read of a few new Z4s that have had the HPFP replaced already.
Not good for BMW... I do wonder if the V8 has the same issue.....

Not surprising, considering all the posts. I am scared of all things "turbo" and will stay away from them, no matter who makes them.

I've had lots of turbos (2 Dodge Daytonas, and 2 Mitsu 3000GT VR-4s). None had actual turbo/engine problems. Although none were kept more than 50k miles. Folks I know with stock Subies and Evos haven't had issues either. For the Z4 to be the first with issues, I'll be upset....

Question for those that have chipped it. Would the HPFP still be covered?

Given that the engine in the 135, 335 and 535 is the same, I would think that the HPFP problems would occur in all 3 models. I really hope BMW solves what is an obvious design defect in the pump because the TT I6 engine is fantastic. I have adored driving the 2 335 loaners that I have had this year.

I don't think that turbo engines are inherently bad or unreliable. My mother had a Plymouth Sundance Turbon in the 80s-90s that was flawless. Similarly, my father's last car was a mid 1980s Saab 900 Turbo that also had no engine problems. The problem with the TT Is not the turbos. It is a flawed HPFP design.

I don't understand how it's that difficult to make a working pump...like seriously.

That's what I've been thinking all this time...


Sorry to hear about the pump, Craig.

Makes you curious as to why the 135/335's don't have the severity of the HPFP as the 535i's do? Same motor so I would assume same Pump yet more failures are least from this board than the other x35 series.

Also in regards to the Automotive ranking people put comfort and handling in the ratings I think. The RFT"s has been the death of BMW. BMW makes people fearful of warranty if they replace it with something else. I was in the tire shop where a woman was told that by her REP. She said she wished they rode better and she has taken it in to the shop for the harshness. They won't blame the tires even though we know they are.

They told her they could replace them with a better riding Non-RFT and she said no she can't BMW told her it would void her warranty!

I wanted to step in but I didn't.

I am glad that I have a good SA or otherwise I would be chewing out SA's left and right for their stupid comments sometimes.

This thread serves as another reason why I am sticking with the 550i instead of a 535i. Not worth the trouble. Now it may be worth trading for the F10 550i next year. I would be willing to deal with FP issues with a V8 TT and 400/450

Is it worse for the 535 when for the other N54 powered cars? My car is right now for the HPFP but I was under the impression that it is quite rare. What is interesting is that this problem is now also showing up in Europe - which means to me that the pump has a design flaw.

Ok guys this is my first post on this forum. I'm really considering the 535i as my next BMW purchase. However the more that I read on here, the less inclined I am to pick one up, leaning more toward the 530i, or even a 545 or 550(which I have read both have their reliability issues). My last car was an e46 M3, so I'm no stranger to frequent visits to BMW and high maintenance costs, but I would like to minimize the maintenance costs this time around. I called a friend who is a tech at the BMW dealership and he says the HPFP issues are across all of the vehicles with the N54 motor. He also said once the HPFP is replaced that he is not seeing those cars coming back in with those issues. Has anyone here had any repeat issues with the HPFP once it has been replaced? The reasons I like the 535i was the blend of power(which can easily modded to almost 400 with just a chip and intercooler), looks and fuel economy(without mods). Any thoughts, advise or suggestions(especially from 535 owners)?
