  1. Does anyone have any information on the PDK filter? I understand that this filter is integrated into the transmission oil pan and is therefore quite an expensive part. Does this filter the PDK gearbox oil or PDK clutch oil? Is there a specified interval on when this filter/oil pan should be replaced?


    That filter is part of the pan cover. The cover and filter are replaced if the oil plug cannot be re-used, which seems to be the case in some early PDK cars.

  2. I'm due for the PDK clutch oil change. I had to request a quote from my local dealer four times. They came back today with $800 for the oil change and $780 for the filter. Is there a filter? Are these prices standard? Will anything besides a PIWIS work on the oil change? Is there a step by step procedure written up yet? Is it reasonable for an indie to attempt this service? And so forth ...

    Thanks in advance for any information you can add.


    I think you should seek another dealer opinion. :)

  3. Slicky Rick: In recirc mode there is no overt air input. You are breathing closed cabin air. Of course, there's always some air creeping in from the outside, but less than when recirc is off.

    The pollen filter, stops large particulates but not gases or smells.

    Your S-Merc cabin fllter does not renew the air, just cleans it from particulates. Are you sure that that filter is not used by external air. The fact that the filter is inside the cabin does not mean that it is strictly used in recirc mode.

  4. MWS:

    There is no tire rotation in 997s. You can exchange tires left to right on the same axle if the tires are not unidirectional but what's the point?

    Second. Never, never mix different tire styles between front and rear. Both axles must have the same exact tire compound/brand/type including N-rating if a N-rated tire. Your adding Hankook to the rear while maintaining PS2 at the front is total folly. The tire shop you used is utterly incompetent. That is why your handling was screwed up.

  5. Interesting, I am going the other way, trading in a 2009 Cayenne Turbo S for a 2011 Targa 4S. I bought the CTTS for all the reasons you list and regretted it not long after. I wanted to own a Porsche and never felt like I did with the CTTS. Anyway my 911 is at the port and should be in my driveway soon, then I will consider myself a Porsche owner, just my .02 from my experience.

    You got that right. The Cayenne is a great ute but it is worlds apart from an 11. I suppose those who seek straight-line thrills cannot tell the difference.

  6. Dear all,

    I own a 997 Carrera 2 with PDK and sport plus that performe really well. However I have a question about PDK: When I downshift from 4th to 3th gear around 3.000/3.500 RPM in normal mode, with the wheel padles, I can feel a kind of "lurching" in the transmission. I have 3.000 Klms now. Question to experts in PDK: Is that normal ?

    Thanks for your help


    Probably not. I suggest you ask your dealer to take a look.

  7. Thanks for the advice. It went into the dealer yesterday and as predicted they could not replicate - the dealer is in a very flat area and the location where the issue happened in 3rd gear is about 20 mins away. They did a full brake check, and everything checked out fine so the theory is it's just the ABS working. I've only done 250 miles so we agreed I'll live with the car for some miles and see how we get to know each other :-)

    That said, I've had several recent Audis and the ABS never felt like a single 'clunk' through the pedal. Usually it's just a pulsing. We'll see ... this is my first Porsche.

    You seem to imply that you observe that when the car is on an incline. Could the noise be the release of the brake assist (which is normal)?

  8. I will be ordering a 2011 911 C2S in the next week or so and am looking for advice on the sport suspension and limited slip differential options. I will be getting the Sport Chrono option and I am seriously considering adding the sport suspension option. This will be a daily driver but I will track it one or two times a year. I tracked my previous Porsche and had made a number of suspension modifications to improve the track experience. However, I am concerned that the sport suspension in normal mode will be too harsh for daily use. Does anyone have an opinion on how hard the ride is on the normal setting for the C2S standard suspension compared to the sport suspension?

    Also, I am not sure whether to get the limited slip differential. It seems like its a bit more that I would need since I plan to track it only 1 or 2 days a year. Any advice here?


    I recommend the LSD which you can get with either suspension. Because we drive mostly on real world roads I did not get the SPASM. The 997.2 std PASM is a great suspension and I can always put in Sport mode.

  9. The Moweraxle is fine but overbuilt/heavy and not as flexible as it should be position-wise. I prefer the product sold by JCS. It sells for $37.50 including shipping - Contact: stumberger_r@msn.com

    1 - It is well made. Well machined metal parts and good fasteners

    2 - Great (light) black stiff plastic backplate - warp-free

    3 - Flexible post mounting attach points, offering multiple offsets

    4 - And most important - light weight as compared to other heavier designs.

    Here are pics:



  10. I've got a 997.2 with PCM and iPod integration. I use an old 20gb 2nd gen iPod in the armrest, and it works great - integrates really well with the PCM. I've been using my Sony Ericsson bluetooth phone with the pcm and it works brilliantly - uploads the phonebook onto the PCM screen etc.

    Now thinking about getting an iPhone 3GS, and want to use just the phone functionality via bluetooth (ie still use the old ipod to drive the music in the car) - that way don't have to plug/unplug all the time. Has anyone used the iPhone via bluetooth, and how well does it integrate? (bluetooth standards seem to vary by manufacturer so I'm loath to believe the tech specs)

    My iPhone 3GS works perfectly in my '10 CS. Same with my iPod Photo. The IPod connector require both the USB and iPod ports connected to charge the iPod.

  11. You want PASM for daily driving. PASM on the .2 generation is just about perfect. And you'll mostly use it in normal mode on the street. The std non- PASM suspension is far more punishing over expansion joints and broken pavement. PASM Normal is not a limo suspension but it does control sharp changes quite well.

  12. The source of the picture is a Cayenne DFI engine. On the intake tract there is air and EGR products. The latter is what we see in that picture.

    I first posted this thread asking a question re the 997.2 DFI engine and this issue. I do not think that this is a major issue - I have since bought a 997.2S...

    Sorry, I'm still not buying in. ...

    What are you not 'buying in'? The problem or a new 997.2? :)

  13. Do not turn off PSM. Leave the PSM button alone (unlit).

    - Turn Sport Plus ON

    - PDK in D

    - Left foot on brake

    - Floor the throttle past the kick-down switch and leave it there

    - The tach should show a steady 6500RPM [and may flash 'Launch Control' (I forgot)]

    - Release the brake and hold on

    Do make sure you do this in a safe area with zero traffic or people around and a reasonable straight-line in front of you with space to stop.

    I have Launch control in my car and have no plans to use it. I own the car and I do not care about drag strip launches. :)
