I waited until I could confirm my problem is solved. After asking the dealer multiple time about vacuum level measured with a digital manometer and never getting a straight answer, I spent some time talking to the tech before proceeding. According to him, the reason the car would start when cold is it was still going through the 90ish second startup sequence with secondary air injection, coupled with the vacuum leak caused by the AOS. Which, to my not-very-Porsche-tech brain kind of made sense. After getting the AOS replaced, along with a cracked brittle oil fill tube and one or two other related minor bits that were also old, cracked and or worn out, the car seems to run fine, was actually quieter than I ever remember, and the stalling problem is resolved. And no CEL since the repair. There was never any big clouds of smoke usually associated with a failing / failed AOS.1 point

I put it in my 2004 Turbo Cab and it works great. plug and play though playing content through your iphone is not as loud as the normal stereo... you don't have to purchase the NAV card; you can use apple carplay... works a treat. Hope that helps.1 point

If the oil cap is hard to remove, you have a high vacuum level in the sump, which is bad for a variety of reasons, including lean stalling. The correct way to access the AOS is to fully warm up the engine by driving the car for 10-15 min, then replace the oil cap with the one in the picture above with a hose that connects to the digital manometer. If the vacuum level exceeds 6-7 inches of water vacuum, the AOS is leaking air into the intake system, causing the lean stall conditions. The normal level of vacuum is typically 4-5 inches of water, which is a really weak vacuum level, so it doesn't take much of a leak to cause problems, which is why we always checked every car that passed thru the shop with the manometer.1 point

Manual is a huge component of my attraction to Porsche. Where I live, 2 similar spec 997.1 vs .2, the price difference is $15,000. i chose a .1 four and years ago. That 15k delta was left in the stock market (S&P 500) and has atleast doubled. Meanwhile my cars only trip to a shop has been a gashed tire caused by road debris. I’ve done all small repairs and major maintenance. (Although I have new issue today) Do you see yourself keeping this car for a year or 2? Or 10 years or more? If you plan on keeping a .1 I’d recommend the following: Swap to a low temp thermostat X51 baffle upgrade in the sump. consider upgrading AOS to aftermarket Ultimate AOS. 50 weight oil instead of factory 40 add 3rd radiator. ignore ALL internet boogeyman stories about the IMS. 2008 era, it is just another moving part. However if you ever drop engine for a clutch or rear main seal then have a seal removed such that IMS is no longer sealed and engine oil will splash in to lubricate it.1 point
