Why are so many recommending a new engine? What exactly will replacing a mechanical lump of alloy do? Did I miss where they found low compression, leak down issues, bad cam timing, etc?
Might as well recommend new headlights because a failing ballast or led driver may be causing RF interference with the car's ecu...at least that has a one in a million chance of being plausible.

I feel bad for the owner of this vehicle and I would be going through the roof. Porsche needs to fly one of their best techs over there and properly diagnose it. Dealer may be nice, but after hundreds of labor hours spanning several weeks, they should have found the solution by now.
I can see several scenarios with what has been going on...

A chafed wire somewhere in the vehicle causing an intermittent issue from day one. Yes, they replaced some harnesses...probably equal to 10 miles out of a total of 500 miles of wiring.

More than one problem to begin with. They repaired the main issue by throwing $15K in parts at it and the other unrelated issue is still present.

They fixed the initial problem but caused another after 200+ hours of tearing everything apart and putting it back together.

If they replace the engine, the problem will still be there. Add in more room for error on not getting things back to exactly the way they came out of the factory. Then add in the MASSIVE loss of value to the vehicle...replacement engine ranks right up there with salvage title imo.

 

Agreed 150%

What's really pissing me off is the lack of communications and game plan .

If I did their way of communicating at JPMC I'd be out of a job along with me team .

Yeah I`d be annoyed at that too

Not trying to defend them but they do have a couple of other small issues going on in the background right now too

Another update ....


Well with a suggestion from another rennlist member , they went and checked every fuse , every module connector , wiring harness , and relay , no luck still dead . PNA is supposedly sending their NA factory service rep Wednesday all day , and just so happens I found an excuse to fly down Tomorrow for a meeting in DC .. Hehe , I guess I'll have to spent the night and " surprise I'm here ! " Wednesday morning .

Have you checked into your state's Lemon Law? NH doesn't seem to have any mileage limits.
If you had it back more than three times, you should qualify. There is also the 30 days out of service but that's business days.

I'd be going for the forced buy back at the very first opportunity.

 

This makes it sound like PNA only has one factory service rep covering all of NA. Surely that can't be possibly...?

 

I was told there is 1 factory rep per X states, except in California, Florida and New England where there are multiple. I'm not sure I believe that, but thats what customer care told me.

 

Yes I have, and was told it's best to hire a lemon law lawyer, but don't want to pull that card yet. I'll give them until the factory rep makes an attempt.

 

let the games begin....

Factory rep: This is very unusual
Me: I got that , but what is PNA going to do about it? 36 days now without my $160K vehicle , needless to say my patients are wearing thin.
Factory Rep: Let me get on it and I'll call you when I know something
Me: Oh I'll be waiting in the customer area or walking around on conference calls, I'm not leaving.
Factory Rep : Oh, OK
Me: I'm not screwing around anymore, I want a solution to the problem, keys to another one or a check in my hand. Those are PNA options.
Factory rep: got it, I'll call my boss and let him know you are here waiting and not happy in any way.
Me: you do that and feel free to have him call me.
Factory rep: Got it, let me get in the shop and take a look, it's going to be a while as I see there is a long list of parts and test procedures that were done already, that I need to do my self for the factory engineers.
Me: Got it and get a red bull or 5, I'll buy lunch if i have too. I want a game plan ASAP!
Factory rep: I understand completely. & walks away

Waiting for the outcome to all this......

 

So three potential problem areas?

Seems odd, three separate systems taking a dump all at the same time on a virtually new high end car?

 

He emailed them the logs , said there were unknown errors that his diagnostic laptop wouldn't tell him what was wrong or the definitions of the error codes . He's spending the night in DC and I'm spending another night as well .

OMG, burmeister, PTV and PASM causing a no start issue?
I presume the seat adjustment might be next one to cause the issue.

He obviously has no idea what's going on. It's probably one of the techs that can plug in PIWIS and do whatever it says to do. Nothing else.

My wife's 08 CTT had an issue with air suspension. Durametric said everything is fine, PIWIS said everything is fine, everything was OK but the compressor just wouldn't start and pump air. The actual issue was the cabling not being able to conduct enough current due to copper corrosion. If we hooked up a multimeter, even it would say everything is A okay but anything above say 10A and it would just produce sparks.
Might be a similiar issue as I'm reading this. It's a bitch to diagnose and go after.
