I had an Audi Allroad that had numerous issue's which I logged and sent a copy to Audi. I sold the car and the next day Fedex dropped an envelope through my door which had a letter stating I could drop my car off and pick up a check at the dealer. I had to call the people I sold the car to and explain to them the situation and I gave them a check for $1000 to get the car back from them. Funny thing was I bought this car used from an Audi dealer in Texas and had it shipped to California and they still bought it back. They bought it back for the same amount I paid including the shipping!

But if you are exercising your legal rights under the law and all they are doing is complying with that law, there is no requirement to remain silent. So make sure they buy your silence and ensure the price is right to justify keeping the lemon out of the public record and infosphere.

Getting a single failed HPFP is somewhat rare now. Stack up the odds of getting FOUR such failures, and you are looking at very very long odds indeed. Get struck by lightning?
Given the odds, I'd think the most likely cause is a combination of other things that are causing the pump (if it is indeed the problem) to fail.
The pump may well have failed.. but WHY. If its a design or build flaw in the pump - thats what the general concern is about and the service action is about. But if its poor installation at the dealer/mechanic, or if its a result of fuel or some other thing interacting with the pump (atmospheric, vibration, fuel lines, your air quality, who knows).. then you could replace it with perfectly good new pumps till the cows come home and still have issues every 6-10k miles.

Agree on that assessment.. I'm betting on something else failing intermitently and finally kicking the bucket. they'll probably replace the pump and find that the car still doesn't start. It's dissapointing to hear that these techs are taking this kind of replace, replace, replace, replace approach. From these higher end techs (like most porsche trained techs) i'd expect a bit more root cause analysis.

My car was burning a quart every 500 miles and then it stopped.....and I can't tell you why?

I doubt the techs are doing this on their own. It is not a cheap proposition and Porsche is proactively replacing a lot of fuel pumps in 09s which seem to be batch related. Sort of like the NSX snap ring issue.

At this point I'd suspect the cause is something else entirely, not the fuel pump.

Since I got the car back, so I probably can't pursue the lemon law. I will see how long this pump lasts.

But the real question is 'why did the pump fail'. Thats not something mechanics typically can tell you. Presumably the pumps go back to Porsche for post-mortem so they can figure out whats happening. Is the pump destroying itself or is stuff getting into the pump thats breaking it... those questions will lead to a longer term solution to the problem.
Depending on the state you live in, the lemon laws may allow you to make them buy it back. Some states' laws state that if the car is in the shop for the same reason x times over a y month period, then its a lemon and you can force them to buy it back. You having the car back may not play a role in that, since it is your car until they buy it back.
