Failure of the main bearing. Worst part of the ordeal is the position as the owner and how I'm at the mercy of Porsche and lack of concern by PCNA.
Jackie is out for blood!!
This could have been real bad. The engine did locked up and if I hadn't picked up on the issue so quickly I would have had the transmission lock up and lost control on the highway doing 70.
I have yet to see proof that not following the break-in procedure puts the longevity of the car at risk.
First question from Porsche: you at the track? 2nd What were you doing? The computer showed everything normal and no issues. the computer can't see why a bearing would fail. The oil filter is the first place the dealership went. The rear wheels were locked! It needed skates. It's the luck of the draw. My car was a Friday car!

If the bearing clearance was incorrect, assembly was done poorly, or parts were flawed, no amount of break in will save you.
Transmissions and differentials are likely more important to break in gently.
Engine break in is essentially rings at this point and those are long sealed by 100 miles.
Anyone with knowledge of engine mechanics and experience building them will tell you that 2000 bloody miles are wholly unnecessary. The manual, if you havent noticed, has 4 million warnings down to dont wrap the seat belt around your neck and slam on the brakes. You dont think the suggestion that you drive gently might be due to lawyers not wanting you to go out and pound your new car into a tree at full throttle. If nothing else, the mold release on new tires would be enough to go a bit easy.

All my previous new performance cars that had manufacturer recommended break in procedures were purchased 350 kilometres away from my residence and the break in period was on a 3-4 hour non stop drive home, I always followed the break in advice during the drive home and didn’t notice any difference in the first few hours because of the highway driving.
My recent TTS was trailered to me and the first time I took it for an hour and ten minute drive I could smell a lot of hot metal, rubber etc.
The second one hour trip was the same and the VOC odours were intense, on the third one hour trip I took the odometer from 170 to 240km and the smell was gone and the drivetrain is already feeling different.
I have noticed a difference in how the drivetrain feels and even how the exhaust sounds with previous cars as they break in but the smell and odour thing is a first, I hope the odours really were the engine and exhaust breaking in and wasn’t something else burning off that shouldn’t have, the car has been perfect so I do think it was just normal burn off that you would only notice if you weren’t driving at higher speeds.

So they recommend not using it at the track or sporting events for the first 3K. But don't they use new cars for their Driver Experience programs? That type of driving can't be good for a new car, then they sell them off as CPO.

All, read above. Spot on
Now if someone can tell me why the first oil change is at 10k and differential oil is not changed along with some sort of scientific reasoning, I would appreciate it.

At the Blackwing driving school I asked the instructor what they did and he said they get the cars for personal use until they are broken in per the manual. So who knows...
An older friend with many cars spec'd told me that the buying the car was a big part of the fun. I thought that was stupid. But then i spent 8 months waiting for Christmas day. that is special as a grown up with very little left that is exciting like that.
Now that I have my car, I know that not following break in is not going to make a bit of difference to my ownership. We were thrashing the living **** out of GT3 last summer with 60 miles on it for a full track day.
However, I am following breakin on my car a bit - the delayed gratification is like foreplay.
Crossed 600 miles today and taking it over 6k is was pretty sweet - unlocked a new segment of the torque curve and the exhaust. Going to make myself wait a week to take it over 7k.
Have fun. These are just machines.

Because engine oil is slowly contaminated by gas, water and carbon which turns the oil acidic and drops it below viscosity over time and mileage. Transmissions and differential fluids are not effected by gas, water and carbon so last longer.

Um... while you are correct - the main reason for early oil changes and/or differential fluid changes is because of the wear/metal shavings that are a natural by product of a new engine/differential - and thus the entire thread Most high performance cars have early oil and diff changes.
