Boxster G please keep us updated. My CPO 09 997.2 also had the High Pressure Fuel Pump, replaced afterjust 3-4months of being put into service.
My non scientific gut tells me that issues w/ the HPFP will only rise and all the parts involved will have to get better.
I've read in the Porsche book at the pressure is north of 1700psi! Good thing im covered for 5yr/100k!
BTW is seems like these problems are not specific to P. Audi has some issues too.

Well, yes, but you're wrong. That's we keep trying to explain politely why. I do realize we're pitting nothing more than a hundred-plus years of engineering experience against a well-established old wives' tale, so I don't expect to change anyone's mind. But every time you say it, it goes into an archive, so we owe it people considering Porsches to give them the facts of the issue. Every time you say it.

Even a multi-billion dollar engineered Airbus A380 is recalled to fix issues, where those issues are fixed in the models released later. It's an absolute fact in engineering, and there are hundreds of examples of it.
AGAIN, I did NOT say first year model is unreliable, but pointed out that later models WILL have LESS issues than earlier models, as all of the issues reported here WILL BE ADDRESSED and fixed not to cost Porsche more moeny.
If you disagree with just the ^above statement^ , I really would lose respect in your opinion in other matters too, as you've been very helpful and knowledgable in a lot of other threads!

There's no need to continue this discussion in negative terms and make it personal. Gary and I have one perspective and Alex has another. The arguments were made and I suggest just leaving it at that.
And to Alex - if you think later model cars have no issues (sometimes worse problems than previous years) you do not follow the industry. I can give you several examples of that. And I repeat, you should not put down the decisions of first-year buyers - after all they paved the way to allow you to buy later year ones.

BTW, I never said later model won't have issues. I said generally there will be issues based on prior experience.
I don't even know why we came to this point... 997.1, 997.2, 993, and the rest are all amazing cars and have and will bring a lot of enjoyment to its drivers while having some flaws that are expected from a complex sports car.

LOL! Actually no.
I honestly cannot be happier with my car. It seriously has exceeded ANY expectation I had before buying it. It is as amazing on the street, as it is on track. I am sure 997.2 is even better, but for now, this does it all for me. I am a manual guy anyways, so PDK which is probably the best selling point for 997.2 is not much of a value for me.
I posted my first impression to the Audi forum I used to visit. No matter how much I improved my S4, I just couldn't possibly correct the inherent family car design of the car. 911 comes out of the factory designed for street/track usage and is very well balanced to achieve both and they've done an incredible job making the car track worthy, while it's still perfect for daily (if you're single)!

The diagnosis on my car is the HPFP as originally thought. The part was ordered and should be here today. I may get it today but definitely tomorrow if that resolves my issue.
Adias made me think of something that I dismissed earlier during startup Sunday morning when my car began to fail. I usually have my car in a warm garage so and this is the first time it was started in a cold environment. It was parked in the hotel parking garage and it started slower than normal. I am referring to ignition and not cold cranking. I dismissed it as I thought it was just because it was cold that morning and was normal. However, when I began to accelerate the car did sputter when I was accelerating out of the garage. Once again, I thought it was just cold weather related. It began to respond after a short bought with that issue. The rest of the day it ran great and performed well until I felt it "missing" or lack of acceleration that evening.
In short, I guess I didn’t acknowledge the symptoms that were there and quickly dismissed them since they went away very quickly.
Thanks Adias for jogging my memory on this one.

as somebody in the market soon for an 09 or a 2010, these discussions are very helpful. my conclusion is that there are very few issues with the 09s and i'd happily buy one. i have a great relationship with my dealer and they didn't hesistate to fix any little nit on my 2007.
OP - congrats (?) on finding what seems to be a relatively simple fix on your pcar. sorry for the trouble it caused you but thanks for the report...

On a side note, my car burned oil during this trip. I made sure the oil level was correct and filled before leaving and upon arrival I was a little over 1/4 of a quart low. I think that it was bit much for a 600 mile trip. I didnt have any performance issues. I will just have to watch it closely until it get more miles on it. Reminds me of one of my 993s so i dont mind the history lesson.

more. This is because the oil is gradually becoming
diluted with fuel or moisture, making it appear
that the oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an expressway,
making it then appear that oil is excessively
consumed after driving at high speeds.
