That's one of the reasons why I went with the 30i Z4 instead of the 35i.
My thoughts exactly and the s30i with a 6 MT and the Sport Package is a hoot to drive.

Love this car so far. I'm sure you will too when yours arrives. Luckily it was 80 degrees n sunny in Socal today so a perfect day to drive with the top down.

You are killing me, it's 16 degrees here in western MD with a 35 mph wind making it feel like 0. Someone needs to tell Al Gore that I think he has it wrong.

A little off topic, but you hit my favorite nerve. Note that they're not calling it Global Warming anymore, but the name is now Climate Change. That way they can take over the world economies regardless if the atmosphere is getting warmer or cooler on any give day or decade.

I hear you.

Back on topic, has BMW ever officially given an explantion for the failure of the HPFPs? I know they switched from Siemens to Bosch about a year ago but I hear the Bosch pumps are failing as well.

My question as well.

My sense is there is a inherent design flaw with the fuel system itself, meaning that in someway the n54 HPFP has to be configured can't be overcome by a pump redesign. Maybe it's the way the pump is integrated into the engine, or something else. Maybe they'd have to redesign the n54. I say this is because BMWs other direct injection engines with HPFP don't seem to have the same issue. Other manufactures use them too.

Again a guess, based on my assumption above I think BMW has decided to take it's lumps cost wise with the n54 HPFP replacements and phase out the engine by bringing out the new n55 single turbo that is rumored to be fit into the e89 Z4 in the next year or two.

This article doesn't speak to HPFP issue but does discuss the new engine.

i would guess you are correct, after so many re-designs they have finally given up on this engine and going to another.

as for climate change, the answer is yes it is and it always has been and always will be. well at least until our sun eventually dies and the earth will be a damn cold place pretty much forever. i believe current thinking is the universe will expand forever, and eventually all stars will be dead, no new ones will be born, and the entire universe will be cold and dark.

as you all know, when you look up into the sky you are seeing light from stars reaching us after many years or even billions of years, like looking into the past. however, if you could magically "go to each star instantly" OR if the current light from each star could "reach us instantly", 70% of the stars you see in the sky tonight are already dead.

Single tubro is worst than twin turbos because of lapping.

Off topic, Al Gore is cheating us on global warning issue. Peking is -14C at the moment and expect even colder in the next few days.

BMW says that even though the n55 has only one turbo, it's less laggy due to the integration of Valvetronic technology, something the n55 didn't have before. It better controls intake induction by varying the valve opening duration.

Yes, Al Gore, the inventor of the internet has conned us all. He was flying his private jet around the world dumping tones of carbon and co2 in the atmosphere, but yet said we were killing polar bears. The interesting thing is back in the 1960's the climate was in a cooling trend and some said the world was coming to an end and it was human's fault. Then the atmosphere got a little warmer during the 70's and 80's and the world was coming to an end then. Now it's getting a little cooler again and I've heard a few of them begin their old chant.

Reference, Mr. Gore, I understand he has a HUGE house in Tennessee that uses something like 50X the energy of a normal house. He probably also has a Suburban or a 1 Ton pickup. I'm all for saving the planet but these politicians and Hollywood types that try to act so green make me sick.

go the the latest headlines on the drudge report. They are talking about how cold it is all over the nation and over in europe. Breaking cold records makes me think that this global warming is a crock.

I suppose you heard about the emails that got hacked and showed the organization Al Gore is dealing with in Europe has falsified the global warming data. It's been all over the news lately and came out just a couple of weeks before the big climate summit - what a joke.

Did you scan the ECU for tuner codes? I use the Bavarian Technic cable. If they find hidden tuner codes you are screwed. I check my car every few weeks and definitely before a dealer visit.

yes i had the performance workshop to remove all codes before sending it in. by the way, do you have any specific tuner codes that you come across? Might be useful to note them. Some of the codes Ive seen myself will be a 30FF.

I have the JB+ set at 100% which is supposed to throw a code once in a while, but I have never seen a "tuner" code on my car. Only codes I got were fuel pump related when the fuel pump was failing. I would have to look back for an email I sent to Terry at BMS to see what the common fuel pump code was. Something like Initial Fuel Release IIRC.

Interesting tidbit.

It looked like the data you scanned was for 2010 - is that right?

I think the rumor I read here somewhere is the n55 is slated for the 35i in 2011 or 2012 (can't remember which year).

Some of the comments on your thread echoed my thoughts and feelings about the rumored change to the n55. Could be overreacting because some people are looking forward to it. But have to wonder what BMW has in mind after all the hype on the n54, which is a great performance engine. My sense, and again, just a hunch, the n54 HPFP issue has to be a big disappointment to BMW, especially after winning all those awards. Makes you wonder what's so difficult to solve with that fuel pump when the same people that designed such fantastic engines. . .

FWIW just my 2 cents.
