I have to agree with what Porshce engineers say there cars recommend, period. Are we smarter then those engineers? I think not. There is a reason why they ask us to use high octane fuel, but a lot of us use regular gasoline. My point here is, why do people try to change things? Who are we to think we are smarter than the other person? Anyway, that was my 2 second rant. LOL... I follow exactly what Porsche or BMW etc. tell me. Except my oil changes and fluids, my hypocrisy stops there.. But I'm running YOKO's on my CS..... There Porsche spec'd as well. If you look at the updated list, you will see what I'm talking about. So, I feel, what everyone should do is go on tirerack.com, search with those guys which tire works well on the CS...Or any other car. I have had great success over the years with them. There are some really good tires out there as well that aren't porsche spec'd but should be and probably will be next year or the following. Just my 2 cents! Good luck!

Did you ever find out what this is? Have you inspected the fluid to figure out what it is? Is it hydralic oil, water, brake fluid? It can be anything. I had the same weird issue with my X5. It turned out to be one of my brake lines cracked over time and it was leaking. If it is brake fluid, touch it with your fingers, if it feels oily it will have a funky scent as well. I would check the brake fluid level as to make sure. If so, top it off if need be and drive it to the repair shop. Hope this helps. good luck.

Ok, here is the update on what my issue was... I hope this helps anyone else that has been having this issue. Took my CS to the mechanic. He had it for the day, did a bunch of tests on the CS. Nothing was wrong with the engine. Did all the tests you can imagine. What he found was bad fuel. Really, really bad fuel. I always put Shell Vpower in the CS. So my only conclusion here is that the shell station I went to last, is not putting the right fuel into there tanks. Scamming the system and we the customers are paying for it. Everyone, be aware of where you fill up. It seems not every shell station is the same. What we did to figure this out is we added some Techron fuel system cleaner and I filled up at my normal shell. We also changed the oils and I used Castrol 5w-40 this time around. I called porshe and they said they have been using this thicker oil for sometime now and it seems to help the engine. I drove the CS all day long, put about 100 miles on it. I opened her up on the HWY as well. The next day, when the engine was cold, I started her up and she was quiet as she has been for the last 5 years. My CS only has 53k miles its a 2005. Like i said this is my experience. My CS is running perfect, quiet the whole time. No more knocking, no more rough idle. No fault codes either.

Maybe it is the fuel pump. The knocking goes away once I reach operating temperature. It's very strange and I can't seem to figure this out. I made an appointment with my mechanic, he told me that it might be the valves? Not sure, he is going to check it out and hopefully figure it out. Anyone else come across something like this?

Hey Guys, I started my CS yesterday and it began to shake and knock pretty bad! This has never happened before. I change my oils every 5k, I changed spark plugs and coils less than 5k miles ago, so thats not an issue. Everything is up to date. I ran for codes and nothing pops up. The only thing that does pop up is the knock sensor bank 2. That has been on for a while now but it doesn't seem to cause any driving issue. Is it battery? I haven't changed that, and I think its original as well. The CS sits a lot in the garage, that is for sure. The last time I drove it was over a week ago. After starting it yesterday morning, I let it warm up and it eventually fixed itself. I drove it to work and opened her up on the HWY as well to maybe get rid of any carbon in the engine. I use 93 oct as well. Now I hear a faint knocking sound from the engine. I rev it up and as the engine drops RPMs I can hear the faint knocking sound. DOes anyone know what this means, or what it could be? Please help!

I would totally do the job myself, as I love working on cars as a hobby. But you see, I have a wife who is chicken SH*T and thinks i'm going to mess up and try killing her on the road. So, I figured I'd just spend the extra 360 and get it done. Which I did and what a great difference these hawk pads are vs. the OEM. Great bite and no dust. Very happy. Happy wife, happy life fellas! Thanks for all your input. I really appreciate ya'll....

Hello All, I just wanted to get anyones input on what the cost should be for a complete brake job on my 2006 cayenne S with silver calipers... Here is the brake down.... I purchased 4 rotors (zimmerman C-coat) Hawk HPS pads front and rear and finally both sensors. I called my indy that I have taken my cayenne there before and many other cars of mine and he quoted me 360 dollars for install. Does that sound good? I think its fair, I just wanted to hear everyone's feed back and there experience on this. Thanks

I gained 2 mpg. ITs not much, but its way better then what I was getting. I was getting 12 mpg combined, now i'm getting 14.5 combined... I was getting 12mpg before because I added a few upgrades, CAI, FABSPEED EXHAUST with Catback system, plus I added wider tires to justify my 21 inch GTS wheels. So with all that, my mpg went down a lot. Now i'm getting 14 city and 19 hwy...... Combined between 14.5 and 15 mpg.... not bad. Shifting is smoother, quicker, an there is more power in the low to mid range. The lag is not as bad as it was before the FLASH. Over all, i'm very happy. For a simiple flash, you get a big bang for your buck. And its not in my mind, you can feel all this extra power in the seat of your pants. Hope this all helps...

This is from vivid.com....you cannot buy it off eBay, contact them and speak to any sales rep. I dealt with Dan Mermalstein, he is one of the head guys there. They ship you out a obd2 connector that goes onto your computer, you download the existing ecu info and then they help you download the updated flash. It's really simple and if your having problems they can log onto your computer and donit from there office. It's really a great product. Look them up and call them for a more detail breakdown.

I can see that no one has heard of this ECU FLASH TUNE before. Well, I took the leap of faith and purchased this flash. I'm here to tell anyone who has a CS that its worth every penny! If you have a turbo, its even BETTER! Very easy, very simple to install. My CS drives better then ever and I'm getting better gas mileage as well. Believe it or not, I am. When I mesh the peddle and get on it, the CS moves like its never done before. The trans shifts smoother as well. I mean everything runs better overall. I just wanted to share my experience with everyone. If anyone was even thinking of doing this, I would shell out the 700 bucks and get it done. Its worth it, believe me I was extremely leary shelling out 700 bucks. But after I asked actual people that have installed this, about this VR TUNE, I was sold. Again, i'm just expressing my opinion. I hope this helps.

Has anyone done a VR ECU flash tune on there cayenne? I spoke to the guys at vivid and they said they have had great success and feedback from customers that have used it. Does anyone know anything about this VR ECU TUNE?
-
Old thread I know, but just curious to see what the results where after doing the TSB? Cause my CS 2005 does the same hesitation only on turns. Please let me know.
-
Sounds like a pulley to me. Can't really tell but doesn't sound like an issue at all. Hope this helps. Good Luck

Sorry to bring this thread back, I know its a little old. But I'm still getting the "p0327 Knock sensor fault code on my Cayenne. There were some other codes that popped up as well but thats all do to my cluster and PCM2 not communicating cause I upgraded to the Kenwood DNN990 Head unit, which by the way ROCK'S! This is what I first received upon start up.... p0327 Knock Sensor 1 Circuit Bank 1 or single Sensor - Value below lower limit value, test conditions are not completed, fault is currently active and is not causing a DTC Light.... p1116 Value below lower limit value, test conditions are not completed, fault is not currently active and is not causing DTC Light.... So I went and earsed all the fault codes.... Took it for a long drive, came back and all codes were still gone... Next morning, started the Cayenne up and plugged in the Durametric, long and behold the p1116 was gone but the p0327 was back. So this only comes upon cold start up. Do I need to change Knock Sensors? All your help is greatly appreciated. Thanks!

There is an option to calibrate the suspension with the durametrix tool? Where is that option as I have never seen it. I have the air suspension on my cayenne.
