So yesterday, noticed the CEL (check engine light) came on (not flashing, just solid amber). Pulled the codes and reset all faults. Reseated my gas cap to ensure it is fully closed. Since I was almost empty of gas, filled up (not that it is very relevant ...lol). Today, after about 40 miles or so, CEL came back on again. Originally there were 2 codes (will post update with those), but after reset, only 1 came back (I imagine the other will return soon but we will see). Pulled codes with Durametric cable/sw, and here is what I got: ENGINE B3901 Evaporative Emission System Incorrect Purge Flow - Upper limit value exceeded, test conditions are not-completed, fault is currently active and causing a DTC light Any ideas on what can be causing this error and how it can be fixed DYI? What maintenance items could be causing something like this? (my first thought - dirty air filters? - i have not checked them yet so do not know if dirty - got the car about 2 months ago). Any help is greatly appreciated. Thanks.

I set the temp on control panel to LO (in mono mode - all sides synced to same control temp as driver front). Outside temp was 72F (as displayed inside car). Measured with my garage thermometer I took off the wall - it is about 4 inches long, I placed the mercury indicator right in front of each vent and held it there for about 3 minutes for each vent. Car doors were closed, windows closed, car turned on idling.

OK. Got more info. I reset the fault codes on Air Conditioner. The only code that returned was code 2600 Temperature flap servomotor rear right. Also, I measured the temps out of the 4 main outlets: Ambient outside temp: 72F AC condition: Set to Mono, LO, automatic (full blast), air recirculation, all windows closed and all doors closed. Measured temp of air coming out of the two front center vents, and out of the two rear center vents: FT LT - 51F FT RT - 71F RR LT - 55F RR RT - 71F So looks to me that the right side of the car is blowing air much warmer than teh left side. If anyone can hep trboubleshoot for root cause, I would greatly appreciate it.

To make sure the battery charging system is up to par - does this vehicle have 2 batteries? I thought it did. If so, do both have to be checked? I assume it would entail to verify batteries are fully charged to begin with? Like do a full charge on battery and then load test it to see if voltage drops below min levels (which would indicate weak battery). Any other ideas? Test the alternator? How (is there a tool that will test it while in the car - I cant imagine having to take it out to test)? Thanks again.

OK. The Durametric cable came in today. Here is what I see (these are the only codes I see in any section at all): AIR CONDITIONING: Part Number 11 Diagnosis Number 11 Current Fault Codes: 353 - Feedback from blower regulator front - Value below lower limit value 2600 - Temperature flap servo motor rear right How much does this narrow down my search? Would this explain the behavior I described above? Much appreciate help with this. Thank you.
-
good. am waiting for durametric cable so will start with that first. just as fyi, are those motors easy to access/change, or is it a pita job? i will post more when i get the cable.

anyone notice if the ceramic pads result in longer stop distance over oem?

this is regarding the 4 zone ac on my car. here is what i have observed so far: When i start he car and turn on ac, the driver side (front and rear) feel nice and cold, but the passenger side (front and rear) feel much warmer. It appears to me that something is not right and wanted to see if someone can help troubleshoot. the heat is not far away here in TX and i would like it resolved before then. Where do i start, whac can be suspect, etc. looking forward to having this resolved. Greatly aopreciate any help.

tire pressure question
ciaka replied to ciaka's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)
I saw the sticker but have always known that most cars display pressures not necessarily for the sake of driveability but for the sake of lawsuit prevention. For that reason many use overinflated values. Is that the case with the cayenne too? Or can I be safe with the pressures they list on the door? They do have 2 values shown (one partial load, and another full load). For my tire size (275/45/19), is shows F:38PSI, R: 42PSI - all for partial load. Should these be trusted? Thanks. -
05 ctt. Have Michelin latitude sport tires on now. Does anyone on here have these and can recommend proper inflation pressure? I know manufacturer of car provides a sticker for pressure, but that doesn't mean it is correct. They usually give pressures that are still good for fully loaded cars (to be safe). So if you can give some recommendations for front and rear, it would be great. So far I have been running 38 in front and 41 in rear.

Have an 05 ctt. I know from manual that there is a service now indicator, and that once lit, 'take it to authorized Porsche dealer for resolution'. 1. Is there a way of displaying how far into the service interval I am ( for example how many miles are on current oil?). Or do I just wait until it comes on? 2. Once lit, how do you reset it without having to go to the dealer? Button sequence or otherwise? Thank you for your info in advance.

I have an 05 CTT. Just checked the pcm and here are the versions I see (took over number from top of display on each screen): On all screens, a line at top says: sw versions: 1.0 - not sure if it refers to each screen. Navigation system: target: / actual: 00179159/4004 Satellite radio: target: 0140/2004 actual: 0140/2004 Amplifier: target: 00016457/3804. Actual: 00016457/3804 System software: target: 04114AD1/1104. Actual: 04114AD1/1104 PCM: target: 04202FD1/2704. Actual: 04202FD1/2704 Living in the USA (TX). What I would like to know is: 1. What would I need to do to update to latest software versions (attempting to update navigation maps). Detailed explanation of what software and version levels needed, sequence of update will be greatly appreciated. 2. Does anyone have a set of discs that would help me (would love a pm on this topic if possible). Again, greatly appreciate the help from you. Have a great day/night.

I took possession of a 2005 ctt. I have spoken to the owner and dealer about the kind of stuff they did with the car. Owner said oil changed about 1500 miles ago. Car has 56k on it. My questions: 1. Should I change oil now or wait (I assume there will be oil change reminder?). Should I wait for the light to come on? It was down about 1 at, which I added to top up. 2. Once light goes on, how do I reset it without having to go to dealer to do it? 3. Should I wait for same with brakes? Pads/rotors? 4. Anyone use the Mobil 1 5w30 synthetic in their cayenne? I know they recommend 0w40, but just wondering. Your input will be greatly appreciated.
