I would check your battery terminal connections as well as the ground to the chassis under the driver's seat. They must be tight and clean free of corrosion.  

Any updates on the humming sound? Was it a differential issue?

Hi working4it

What prompted you to change the differential fluid? Were you experiencing any issues? I have a humming vibration coming from my front right wheel area that I'm suspecting is differential related. Thanks.

Hi,

I just bought a used 04 Cayenne S. When I start it and change it to D from P....it goes to D2. Is that normal? Shouldn't it go in D1? If i use the tiptronic "-" it goes to M1 but if its in automatic mode it always starts in D2. I didn't pay attention to it until yesterday. Did I get ripped off? Any response/help is appreciated.

As others have stated it is normal. Also note the transmission will switch to D1 if you drive under 5mph for a few seconds after a standing start at D2.

Congratulations on your Cayenne S.

I had a problem with the rear hatch switch on my Cayenne S and it had to be replaced. As a temporary way to open it: Inside the cargo area at the rear hatch door, remove small square plastic cover at the bottom center of the tailgate, stick finger in mid center bottom feel lever and lift up.

The cardan shaft was about $250 I think. $21k seems like a lower than average price. If it is clean with no accidents that would be a decent buy.

I have a 2004 Cayenne S and I recently received a warranty extension notice from Porsche on the coil packs so maybe 2005 is also covered.

Ask your mechanic if the 3 plastic coolant pipes underneath the plenum have been replaced with the aluminum ones. Mine failed around 80k miles and that was a tough job to replace and expensive if you let a dealer do it. Downtown LA Porsche was quoting $2,500 for the job.

My right side horn stopped working and that was replaced for free under extended warranty. But it was am easy $100 job if you did it yourself.

Last thing is the cardan drive shaft. Mine broke and was repaired under warranty.

That's the experience I've had with my cayenne. The car runs wonderful and I have no plans to replace it.

Good luck

What I'm curious about are the people that have proactively got the coolant lines replaced? My thinking is that if it's going to happen eventually, I'd rather get it done proactively, rather than waiting for it to happen and then potentially cause other problems indirectly (e.g. starter). I only have 27k miles on my 2006 Turbo S, but I'm not sure if its a matter of miles or age for the coolant lines to go. At this point, I'm more inclined to just bite the bullet and proactively get the job done. What are your thoughts?

I was not proactive and just waited for it to happen. My pipes failed at 67,000 miles (2004 Cayenne S). I was driving at night and got the low coolant warning on the freeway. I knew what just happened and exited. I filled up my coolant reservoir with some distilled water I was carrying in the trunk for this very moment and made it home 20 miles later. I ordered replacement kit from Sunset Imports in Beaverton OR and my parts arrived in 2 days. I spent most of Saturday replacing the plastic pipes with aluminum ones.

In total the Cayenne was out of commission for 7 days from the point of failure. If the car is not your daily driver I would just wait and keep the cash ready. If you depend on it for regular use then I would plan to change them proactively at a conservative 40k miles.

I recall there was a DIY on how to replace the coolant pipes but it looks like it was removed. Anyone know where it might have gone?

To turn off the air conditioning completely press down the fan blower toggle switch until the display reads "Off". This shuts off the compressor and the blowers.

design flaw?

Naw...just dirt, leaves and such. Do you park outside or in a garage?

Hi can anyone tell me the location of the drain holes so I can unclog my AC drain line(s)?

Thanks!

I had the same pixelated display problem and removing the battery ground for a few seconds worked for me as well. As an EXTRA bonus, my TPMS "Workshop Required" warning also went away and I have my TPMS working again!!! I am so happy that I am not going to spend the $2,000 the dealer quoted me for a new display and new tire sensors.

Pictures attached for posterity.

US model

Under the black Y-pipe between the air filters and the throttle body is a vacuum line connector. I managed to snap off the plastic side tabs when trying to disconnect it. I would appreciate the part number as Porsche Downtown LA could not find it for me. Thanks!

Here you go.

GENERAL SERVICE MANUAL

Post #2 has the service manual in .pdf format. The service manual has a step by step for the spark plug change out.

Hi,

Does anyone know what size is the triple square bolt for the stabilizer bar attached to the passenger side of the engine? I want to buy a triple square bit for it.

I drained the oil out of the bolt closer to the filter and when it was done draining I was able to drain about another quart from the second drain plug near the differential plug. So if you don't drain both, you would probably have at least a quart of old oil in there.

On a side note, I stripped one of the bolts that holds down the driver's seat when I was changing the battery under the seat. I had to use a bolt extractor to get it out but it worked after hitting it in place a couple times with a heavy mallet.

Something like this tool to get out the hex bolt. http://www.irwin.com/irwin/consumer/jhtml/...IrwinProd100509

Good luck.
