Instead of wasting people's time and money,why don't they learn how to use a scope? Dumbas**s... Look at the cam and crank correlation and I guarantee you it will become obvious that the waveform on that particular cylinder(s) is off...

You are going through the protocol. This is the standard procedure shop technicians must follow per the aforementioned PAG bulletin or else no reimbursement by PAG. Once apart the photographs of the camshafts and valve levers are sent to PCNA for Options 1-4 determination. Hope you get Option 1 blessing!

It's not like this is something new to the dealers. They certainly should all be aware of the engine issue. If they haven't, shame on PAG.

from what i saw today, the dealers are aware of the problem. when i pulled in they already had the tech sheets ready. its just a matter if that dealer sold enough gt3s that are hitting the track and if those are going down. my dealer said i was the first one that they had to deal with so far and they were very receptive of what happened and the data i brought them from the track and what i had read on this forum and i think they are handling it well. fingers crossed.

PAG dictates EXACTLY how and when things happen. Including swapping coils and plugs to verify misfires, even with a known issue.
As an ex-dealer technician, who also personally dealt with this exact situation with one of my close customers, I can tell you that we (the parts swapping gorillas), my dealerships management, our regional rep, and even one of the guys Porsche trusts most in the US, could not sway PAG to fully replace an engine up until the very last moment, even with metal debris scattered throughout the entire system...
So as much as we appreciate your kind words, you're f*#king clueless. And exactly why most qualified technicians get a bad taste in their mouth, while fighting the system we all hate, in just trying to do their jobs properly. Or quit and move on in order to not deal with warranty work, PAG, or customers like you.

I have been reading these forums for the past 4 days now and this seems like a little more serious then meets the eye. is it really too coincidental that all these problems are surfacing "all of a sudden" ? i had a 997 and 997.2 gt3 and i never heard of the same issue over and over again, like there is a script that these cars are following. forgive my ignorance in conspiracy theory but there is something definitely wrong here. also would like to add, did your tech or dealer have any experience with rebuilding or diagnosing gt3 engines? i don't even think i have that kind of faith in my dealer at this point, i hope I'm wrong.. btw i communicated with your tech today via text and he mentioned what had happened to you..sorry to hear..i definitely feel your pain....

My dealer called me and said my car was ready for pick up. Do you by any chance have the bulletin number so I can ask my service advisor to look into it?

I'm really surprised that Ray Catena was already on the issue. I bought my GT3 from them and serviced with them for about 6 months. I was not a fan at all. Was always waiting for call backs, never got my car back on time, I even brought it in 3 times for the same issue and they hadn't resolved it. That's when I made the switch to service at Jack Daniels. Their customer service is impeccable. The advisor has called me twice since I dropped the car off and they even have this program where the technician working on your car sends you a video of your car, showing you the car and issues as he walks around and narrates.

That being said they hadn't brought up any bulletin to me so I definitely am concerned. I intend on driving the car very swiftly on my way home, shifting at 9k multiple times, in order to recreate the issue. It's not likely that I can recreate the issue being I won't be getting the car up to track temps but I'll give it a go.

If you can just post that bulletin number and keep us posted. I will let all know how tomorrow goes.

well put, i agree, PAG isn't going to just throw engines in these cars without due diligence, especially if an entire engine isn't needed and if they did i would loose respect for the system. diagnosing problems occurs in a step wise process in order to get it right, its what we do in medine (I'm a "person mechanic") and its the proper and thorough way to diagnose...not every problem or illness is cancer...

Please go back and read what I've posted. Where did I mention that they should go straight to replacing the engine? That's absurd! That is the exact opposite of what I'm preaching here! I'm talking DIAGNOSTIC DIAGNOSTIC AND DIAGNOSTIC. HOW MANY TIMES HAVE I SEEN DEALERSHIP TECHS SWAPPING PARTS???!!! YOU HAVE NO IDEA!!!
Forget the GT3,this happens across the board and after warranty the swapping game and missed diagnosis is paid by the customer. Because it's faster for you to swap a coil instead of looking at a coil ramp. And you work flat rate. Take a fat guess,if it works,you've just saved yourself 2 hours of diagnostic.

Thanks, I had seen this on the other thread but was unsure if this was the literature you were referring to. I just attached that to an email sent to my advisor and asked her to call me in the morning.

good luck...to just clear codes and send you on your way seems too easy...esp in light of what is going on in this forum. let us know how it goes.

Once again, says someone who has no idea how the process works...

I didn't state that you mentioned "we" should go straight to replacing the engine. Because it didn't seem like the focal point of your rant, I merely left out all of the steps that are REQUIRED, as per Porsche, before replacement (or partial replacement) is performed. Which in the end, is the goal in resolving a customer's issue who spent $150k+ on a car with a failing engine.
I, as one of the aforementioned parts swapping gorillas, knew exactly what I was dealing with and why. So before I jumped to scopes and cam timing issues (or swapping parts), I checked the oil filter for debris.
Even after informing my contacts within PCNA of what we found and more than likely why due to the material present, I was still forced to follow pages upon pages of steps to confirm what we already knew.
Step 1 after clearing and verifying? Swap ignition coils and confirm fault within same cylinder(s).
Step 2? Swap spark plugs to confirm again.
All dictated, and required, verbatim by PAG. And all while I was losing money as a flat rate technician.
But I guess we should have just called you instead...

Ok,thank you for clarifying how the process works. If that is the procedure you have to follow,I believe it wasn't fair of me to blame the whole thing on the technician. It's just that I've solved too many issues in different cars by doing a proper diagnostic,after people have been charged ridiculous amounts of money at the dealership and the problem was still very much existent. And BTW,I am very much aware that warranty work doesn't pay.
I can't comment more on this procedure that PAG has imposed on you,except that it's a waste of time.
I'll leave it at that and apologize for the name calling. I do realize there are good technicians out there,just harder to find these days...
Take care...
