RECALL on 991 GT3

Seapar I just picked up my GT3 yesterday from Bellevue for a check engine light and was told about the bulletin. The dealer didn't have the new parts in stock yet.

I e-mailed my service manager and cc'd my sales rep this afternoon and got a quick reply (on a Saturday!) from both. The recall is by VIN and my 2014 is not included although another customer's new RS was. I have to say, this kind of response from my dealer is why I keep going back to them.

I am told I have a TSB on my car, but Porsche has not issued a written recall for it. So the tech doesn't know what is is about yet.

BTW I worked in Philly in the early 80s. Became a fan of Bookbinders as well as several cheesesteak joints. I loved the city.

From what I've seen online so far it appears it's a faulty coil. If that's the case, why are they changing the style of sparkplug at the same time... Changing the sparkplug, to me points to something other than just the coil wasn't manufactured correctly, or had a few factory escapes...

Just kidding!!!! But with all the cheating VW has done, it wouldn't surprise me if the 991 GT3 wasn't also engineered around the emissions testing.

I don't remember the build date exactly, but it arrived at my dealer in Philly the week before Christmas last year.
Last 4 of my VIN is 3636

So do I. I think there is more to it myself. I bet all 991 GT3 will be included eventually. The letter states an ECU reprogramming for mid range. That is strange. I am no skeptic, but this may be a pre-emptive emissions strike. As the aftermarket header/exhaust guys are figuring out, when given more air, there is a weird dip in mid range RPM. There is overlap of the valves, where the exhaust valves stay open, allowing fresh air into the exhaust system. Perhaps this is right where they get tested? This would dilute the outgoing dirty air, at the cost of performance at a specified RPM. Another factor to be curious about, is that Porsche states the new 911's PDK can slip both clutches, providing a virtual gear between gears. Likely also done for emissions. Anyone want to bet the current PDK already does this? I bet when it is all said and done, the demise of the manual transmission will be due to emissions limitations, more than just performance reasons. And the eventual demise of the NA motor will also be due to emissions. What tends to bother me, is that in the big picture, the turbo motors are just another engineering fix to get around emissions. During testing, those turbos are not spooling, in essence, running like a lower HP engine. Yet, during real world use, the turbo motors are no better. In my last 335 BMW, it would get decent MPG when cruising on the highway, and just terrible MPG in real world in town driving. Even take the PDK auto mode for example. When the GT3 is in normal auto mode, the car shifts to 7th gear right away. So much so that it doesn't feel like a GT3. Coincidence? Do you think Porsche wanted to make the GT3 as boring as a 4 cylinder automatic Camry? I think they were forced to to make it pass emissions. And in everyday driving, we all run it in manual mode or sport auto.....producing much more emissions and burning a lot more fossil fuels.
All just speculation.......of course.......

Suppose we'll find out soon enough. We have logs of seapar's 991 GT3 before any changes, will be interesting to see what they look like after the change...
