  1. 2012 Cayenne Turbo, 209K miles. Stock Prosche parts and tuning. Durametric reads these codes, if driving around city streets not in sports mode. P1071 Mass air flow at idle speed implausibly high (fast deviation) P0068 Mass air flow implausible. Value below lower limit value These codes seem contradictory. Seems to idles and perform perfectly, and the auto shut of feature, activated with brake on a stop lights, also works as before. Air filters are new as is the MAP (Manifold Absolute Pressure Sensor). Wires seem securely atta
  2. Durametric reader, shows two engine codes: P0346 Camshaft sensor 2, upper limit exceeded. P0050 O2 sensor heater control circuit (bank 2, sensor 1), no signal/communication. (It's December and cold in Utah near the mountains.) Vehicle seems to idle and run well for 206K miles. Suggestions please on what to do and how to proceed with these codes? Thank you.
  3. For the last 9 years (and over 140K miles) my daily drive has been 1999 C4. I live in Sandy, Utah, near the mountains (15 minutes from Snowbird), and somes take this car up skiing (skis inside the car always). It does well in the snow, with 17" Blizzaks during winter months. I use no more than 36 front 38 rear, and a pound or two less if there is a fresh foot of snow to plow through. Sunner with Michelin Sport Cups 33 front 35 rear, since it gets over 100 degress most of July. Too high pressure especially on winter tires, on a freeway gives you the feel of fishy tail as you change langes.
  4. Thanks for this thread. I just replaced mine in my 1999 C4. $14 for same part number: 996.606.103.01. Hardest part is locating it, which isn't hard -- took toward the front of the car, that end of the tranny; mine was on the passenger side. Needs a 19mm wrench with short handle, or of course a crescent wrench.
  5. 1999 C4, 182K. Runs great, strong, no oil leaks, or issues (I've owned it since 38K miles). There's much to be said for ontime, regular maintenance.
  6. Thanks for the direction and courage it provided, Loren. The cover is located above the passenger foot. There is a small Torx screw, in the middle of the cover, right near the bottom, i.e. the hinge line, of the glove box. It helps, or is necessary, to remove this. Pull the cover down at the glove box hinge line, then pull it slightly forward, to remove. It takes a strong pull to pop it free. There is also a plastic air channel tube that has to be removed before one can see the image under Loren's #2, above. A 7/32 socket will remove the two screws that tightly cover the openi
  7. Can some one get me started, on how to change the cabin air filter, or particle air filter, on a 2009 Cayenne V6? It is definitely different from the DIY for 2003-2006 models. thanks in advanced.
  8. Thanks Loren. And then do you always replace rotors in pairs? And does replacement of rotors necessitate replacement of lug bolts?
  9. Loren: Per your post above, at August 09, 2012 - 09:44 AM: If a lug bolt hole is stripped, are you recommending replacing the rotors on both sides of the car, and replacing all the lug bolts? When would one replace lug bolts in the normal course? if they get rusty, or just age? Mine is a 1999 C4 with 177K happy miles which I've owned for the last 140K miles and 9 years. Thanks in advance.
  10. So, I at mghorayeb's insightful and most helpful (if less than obvious to me) suggestion, I obtained a whole new roof cassette assembly (everything but the motor) on ebay shipped to me for $360. It came complete the the exterior painted roof panel, which was replaced with my own. The part was was from the same model and year as my car, but one with half as many miles as my car has. Thank you mghorayeb. That saved me $1K in parts. My local shop charged me $600 (i.e. 6 hrs) for the remove and re-install, and it works well now, again. Moral: I think I kept my roof lubed, but I'm sure to co
  11. Mghorayeb, thanks for your reply. I took the car to my Porsche mechanic, a shop dedicated to Porsches and European cars. Apparently the sliding roof has come off its rail on one side, and he thinks a cable is broken. He's quoting me $1400 in parts (including a "cassette" and two other less expensive parts, but not including a motor, since my motor is apparently OK), and 5 hours of labor. I'm more than a little surprised that fixing a sun roof is about a 2K hit. Does this seem reasonable and appropriate?
  12. 1999 C4, which I've owned and enjoyed for 7 years, since 38K miles (now 159K miles). This evening the sliding sunroof was sliding open nicely. It only slides open if I hold down the button. But then a slight bit of rough road, at 35 mph caused it to hick-up a bit (clicking noises). And I probably briefly pushed the wrong button(s). Now it's wide open (slid all the way back, i.e. roof open to the sky). It will only shut about one inch, then stops. And repeated attempts make it close back up only result in opening back up that one inch. The tracks look clean, and were last lubricated 2
  13. Also tighten the bolts on the strutts. That cured a nasty squeek in mine that developed over the winter..
  14. I recently had similar symptoms, but with a 1999 C4 at over 140K miles. Try cleaning he throttle body, and the mass air flow sensor (with electrical spray cleaner). It sounds like an leak in the air intake system (which is what mine was). Indy mechanic uses a smoke system to check for leaks. Wasnt' that expenseive to diagonse and fix. Make sure the oil cap is on tight, and fits tightly (mine also required some smoothing of the interface where the oil cap screws on).
