Hi Everyone, had trouble starting my 2011 997.2 this morning. Got a message that said "Reduced Engine Power". Had to try several times before car started. Never happened before. I searched on forum and it seems to be related to a fuel pump issue but in the older models. Any 997's dealing with this?

Thanks!

I'm sorry to tell you that your dfi engine has suffered terminal coking up exactly as designed at <1 year old. Owners of 997.1s who have suffered half a decade of sleepless nights with IMS and RMS anxiety will be along in a minute to falsify sympathy for your misfortune and tell you they told you so

Made appointment at dealer for Monday. He thinks its a fuel pump. Wondering if other 997.2 owners have dealt with this.

It is very likely your fuel pump or injectors. BMW has had major problems with this issue.

Have not experienced this problem. Fuel pump seems a likely culprit. Good luck.

I have a 2011 C2S. Have not experienced this problem. I asked my local dealer if 2011's were subject to the high pressure fuel pump service bulletin (WB08, I think), and he said no.

About three weeks ago, my '09 997.2 C4S "woke up" one morning with what sounds like the exact same symptoms. It was the high pressure fuel pump. I have just under 60k miles on the car, so I'm out of warranty. But, since there's a service bulletin out, they replaced it FOC. So, the only thing that really stunk about it was that I had started the car to go to an autocross

You're discovering the chain tensioner flaw of the 997.2 engines. EVERY 911 made had some issue with its engineering. First it was the chain tensioners, now it's the Direct Injection system.

Hi Dan
Why is it that a $90K + car has all these engineering flaws, but a $20K Camry will run forever without a problem? It reminds me of prep schools, the more you pay the less they go to class.
I hope all is well on the Left coast. Things are cooling down here in Nudehampster. I hope to get another 6-8 weeks of driving.

Take Care

Keep in mind that these are high performance engines. Porsche gets around 400 hp out of a 3.8 litre engine. Ask Honda or Toyota to do that.

When you are pushing the engineering edge there are going to be issues that are not quickly solved. Sadly, we have always had SOME sort of shortcoming in Porsche engines. Some of the stuff is just plain stupid. Back in the early to mid 1970s Porsche insisted upon using magnesium for their engine and transmission cases. The engines leaked like a SOB, with bolts pulling within a thousand miles of delivery. Ultimately, they went to aluminum cases in 1978 and that problem was solved. The magnesium cases only were going to save them some 30 pounds back there.

I am trying my damnedest to get my Rear Main Seal to leak. And praying every night to get my Intermediate Shaft Bearings to fail. But try as I might, the thing just keeps running and running, right up to redline. No leaks. No metal in the oil filter. No catastrophic failure. I can't believe I never had to call 1-800-Porsche. What the hell good was that service if I never could use it???

If only I had this 997.2 fuel pump problem, maybe, just maybe....I could get an engine failure. But alas, I only have a mere 997.1.

Maybe I should start wishing for a 993 check engine light and carbon choked valves...

Oh no...I think I just jinxed myself.....

Ok. just got back. They tied it to low voltage. Not fuel pump. So lets see if that fixed the issue.

The fact is that direct injection with these HPFPs and piezoelectric injecors are not ready for prime time. Auto companies are committed to these systems as they do offer some modest benefits in fuel economy, power and emissions. They are NOT, however, as reliable as the traditional port injection systems. Plus there is the carbon buildup issue. Eventually, the auto companies ( or more accurately, the fuel system manufacturers) will figure out a solution. I was happy to be able to get my son a new 2012 Mazda 3 with port injection. The newer 2012 models will come with DI to achieve 36+ mpg rather than the 33 mpg on the highway. Yeah, he will pay a little more for gas but will be saved a lot of headaches and time at the dealer.

Hilarious. After nearly 4 years with not one single incidence of coking in a 997.2 dfi engine anywhere on the planet, yet said with absolute certainty. Spoken like a true 997.1 owner!

Well, let's see after a number of them get to 60K miles.
