Noises like these can be a real pain in the a--. The perceived location can be very missleading. The FIRST thing to do is call your dealer. If it is good they will have a noise locator which is nothing more than a unidirectional microphone on an isolation wand connected to a powered headset. Take the tech for a ride on a rough road and he can positively locate the exact position of the source. Then you just fix it. No guessing. If it is the B pillar, the only item of significance in there is the seat belt mechanism which you DEFINATELY do not want to mess with. Good luck.

I also have a 2006 C4S but mine is a manual. Not sure if the Tiptronic uses the same differential or not. Does the differential run on automatic fluid or does it get it's own gear oil? I am going to run a little experiment with different gear oils and will post the results. I would not do anything else to your car. In your case I think there is too much water under the bridge. There is always collateral damage with any large job on these cars and you have had several. I have had two 911s that developed issues that could not be diagnosed or were fatal flaws. I traded them in. You are obviously unhappy with that car. You need to get one that puts a smile on your face every time you get in it not grief. All you are going to do by changing parts is make things worse.

I have an upgraded system similar to Hank's. The car is an 06 C4S which came with the Bose/PCM system. This system operates on a MOST fiber optic bus. You can not just hook up a standard head unit. Fortunately, there is a company down in Fort Lauderdale, FL called NAV TV that makes what they call a MOST head unit replacement module. It is essentially an analog to digital converter that outputs through a MOST fiber optic connection. It costs $700 but you get to keep the entire Bose system. I have an Alpine INE W927 HD, a unit very similar to Hank's Pioneer. The escutcheon plate is readily available in the aftermarket converting the polygonal PCM to a standard double DIN. The finish is the factory identical golden silver. The total cost including installation will be about $2,400. In the greater Boston area the only place to go is Sound in Motion in Brighton. Rock and Roll.

Hi Brendel, This is the drivetrain lash I refer to in another thread. My car does exactly the same thing and it only has 14,000 miles on it. The Porsche tech says this is normal or rather that the car is performing to Porsche spec I am 95 percent certain that it emanates from the transaxle,

There is a depression and drainage hole in the bottom of the airbox. You can pour water down that snorkel without any ill effect.

Hi, There is no switched 12 volt source in the overhead console. You will have to run your power lead under the head liner to the left A pilar down to the fuse box. I would not mount it to the rearview mirror. It will be to low and interfere with your site lines. Mount it to the left of the rearview up as high as you can get it. Unfortunately, I have not seen a decent aftermarket mount. The suction cup affairs always fall down eventually. What I did was to take the metal bracket from the suction cup mount that came with the Escort and using high strength medium thickness cyanoacrylate glue attached it to a piece of ebony 3 X 3 X 1/8 " . Using 3M mounting tape this was then attached to the windshield just in front of the headliner. It is minimalist, attractive and you will have to break the windshield to get it off. You can use any hardwood. Just spray paint the entire assembly flat black. If you have an Escort you need to get the "Live" module. It is way cool.

Great Thread. Having owned six 911s and driven both 7speed and PDK 991S's I figured I'd throw in my 6 cents. Yes, the 911 is slowly getting larger and it does not give you the same connection to the road as it use too. Lets face it, the days of manual steering and clutches are gone forever (unless you are crazy enough to get a Caterham 7.) But, it is still a timelessly beautiful car and it is still the ultimate road weapon. Those of you who have driven a Ferrari, a Lambo, a Corvette, or a Viper know exactly what I mean. The 911 is still way smaller than them all and with those elegantly thin C-pillars offers a panoramic view of the road. You know exactly where all four corners are and can dive in and out of traffic with utter abandon, stop on a dime. I simply feel safer in a 911, any 911 than any other car. The current cars are safer and more powerful than ever and I definately do not miss the tranny, clutch and lag of the early Turbos. I'm also not nuts about the headlights in the 996 series. My personal favorites are the 993 TT and my current 997 C4S which are both crazy cars. It is enchanting how these cars have different personalities. My C4S does this real trashy burbling growl when you start it up cold. Big smiles every time. The new series is true to form. It does not feel larger to me. I do not like the PDK but then I guess I'm an old fart and conseated enough to think my right arm is the best automatic going. The 7 speed shifts well. The solenoid on 7th is totally transparent. The transaxle has more lash than I would like. I feel a bit weird with the shift lever up so high. The steering is nicely weighted, accurate and lifeless. The 997's steering dances in your hands. You feel the road and everything wrong with your front wheels/tires. I'll miss that. Hopefully, Porsche is getting enough grief from us that they will fix it before the 991 Turbo comes along. Most regular folks will unfortunately think the steering is better. These are also the people who would prefer a gentle voice. A 911 is SUPPOSED to howl like an angry chain saw. The sound symposer deal is worse than silly. Give me the aftermarket exhaust please. But, what I miss most in the post 993 cars is the wonderful click the doors made when you closed them. It said I am one tough SOB. I always delete the badging. Way easier to keep the back side buffed out nicely. The Nissan GTR is the ugliest thing on 4 wheels I have ever seen.

It is the key battery. My 06 did the same thing. Replaced the battery and life is good.

Hi Loren, A local Porsche specialist thought the same so, for short money I replaced both rear sway bar links...no change :-( Hi ,Logray Both engine mounts and the tranny mount are in fine shape. I never go to the track, but every day is a track day, you know what I mean ;-} I'm pretty sure the problem lies in the transaxle. Although some people have incriminated the dual mass flywheel. A brand new 991S 7 speed does EXACTLY the same thing. Also drove a 991S PDK and it was fine as far as PDKs go. I will never buy one. Just not sporting, the free wheeling business is plain stupid, its another 100 LB where you least need it, and my right arm will feel neglected.

I picked up a 6 speed 2006 C4S Aerokit last June with 6100 miles on it. I noticed right away a "clunk" in the seat of my pants with rapid transitions on and off the accelerator. This gets much worse in Sport mode (more aggressive accelerator programming). The dealer says it is normal. None of my previous 911s did this. If I drive real smooth I can avoid it. I drove a brand new 991 7 speed recently and it has the same exact maldady! Anyone with any ideas???

I had an Audi do exactly the same thing! It will happen again under the right circustances. The oil level sensor works by "seeing" the air/oil interface in your crankcase. Actually I think "hearing" may be the better term as I believe the sensor is similar to the one used in medical ultrasound machines (sonar). For instance if there is condensation on the surface of the oil the sensor will not see/hear the boundry correctly and report a low level. Once you stir the oil up (off idle) everything returns to normal. Do not add oil!
