'09 engines fuel pump failure?
I read elsewhere reports of fuel pump failures in the new '09 engines? Anyone experiencing that here? Is that a batch fluke or part of the DFI growing curve?

BMW had widespread fuel pump failures (07-08) when they switched to DFI in the TT engine so I wouldn't be surprised. Yes, mine too went into the dealer on a flatbed. However, I find Porsche to
be generally much more reliable than BMW so it might be a fluke. That being said, I'm going to
wait till next year for DFI and PDK.

No problems here so far.. but only have 1200 miles and 3 months on it so far. Me, I couldn't wait till next year.. who knows, I could be dead by then and would have missed out on the joy of driving this baby for 12 months!

I think we have heard of just one problem right?

My 09 standard Carrera has been perfect so far.

I guess I better go take mine for a ride and see what happens. Four thousand miles and nothing so far.

The new fuel injection system requires higher pressures if I'm correct - so it just might be a few off pumps while they are switching to the new system.
Worst case - a few folks will get there's replaced under warranty and never bothered again. Let's just hope the problem doesn't get worst as the cars age and a few of you get stuck with a repair once "Naked" (out of warranty).
Fingers crossed - its nothing.

This is the potential culprit:

Maybe jumping in prematurely here but - two episodes of "reduced engine power" warning with 2009 997.2 S (7000 miles) going into a near "limp home" mode. Also taking 2-3 times longer to crank when starting just last two days. Have an appointment (if I can get there!) - will keep any interested posted on findings. It sure sounds like a fuel pump failing.

As others have touched upon new DFI engine requires fuel pressure...
But high pressure gasoline pumps are rather new.
And gasoline does not quite have the lubricating qualities diesel fuel has.
I know from my time with my diesel VW ensuring engine received only highly filtered fuel with *NO* water was critical. Skimping on fuel filter services and water draining intervals was a no no.
Also, some owners recommended using a diesel fuel conditioner that supposedly helped provide some additional lubricating qualities to the diesel fuel and thus help the fuel pump.
Low sulphur diesel fuel lost some of its lubrication feature not directly due to the removal of sulphur but the process by which this sulphur was removed had a side effect of reducing the diesel fuel's lubrication feature.
I'm not a big fan of fuel or oil additives but Swepco 503 fuel additive might be worth considering.

I'm going to go out on limb here and suggest that with these new DFI engines buying quality gas, fresh gas, and avoiding running gas tank real low is going to be even more important to avoiding fuel system from pump to injector troubles.
And aggressive fuel filter service and air filter service intervals can't hurt.
I don't even want to think about what new cars that remain idle for long periods of time, unused for long periods of time, what effect this will have on these new engines and their very sophisticated fuel filtering, pumping, and injecting hardware.

of nearly 1800psi. This is no where near fuel injection pressures required by diesels (some can require 10 times 1800psi or even higher!).

I agree. Very good post. Since I started this thread I heard of a couple more HPFP issues (1 or 2) and all were taken care of quickly by replacing some internal parts.
