Does anyone have or know where I may have the bolt torque specs for a 2008 Cayenne Turbo? I need pretty much the specifications for all the bolts and nuts that would be included in a block replacement. I'm getting the back rebuilt by 928 Motorsports and reinstalling with an experienced friend. However, it's nearly impossible to find the specs for these motors. Additionally, if there's a place where I could find a complete 957 workshop manual, could someone please advise? Thank you.
I'm unable to connect to the engine module on my '09 Cayenne with my new Durametric cable. I called tech support for an assist and was told that they are still working on coding to allow for connecting the 957 to the engine module. The Durametric website does list the MED9 for V6 as being available for reading/clearing codes. Wondering if anyone else has found a way to get this to work. I'm using version 6 software.
I recently bought a Cayenne S 4.8 from 2008. After a month the HPFP went down so I repaired that (900 euro), no problem if it is just a standalone incident but it seems to be very common for the 4.8 engines. Mine was already replaced with the former owner in 2010 and 2011.
My engine was replaced in 2010 by Porsche and now this engine has around 100k kms (so the second HPFP failed just after a couple of thousand miles). This made me thinking about the build quality of the Porsche engines. The HPFP is not Porsche made I guess (Continental is written on it) but if "I would be" Porsche, I would look for another manufacturer for these parts. So I already got the impression that they are not as typically German as I thought. Then I got in touch with other Cayenne owners over the internet/facebook etc. And the first 10 owners (with a 4.8 engine) warned me for cylinder scoring because they all had their engine replaced or sold their car because of this problem. I knew the 4.5 had this problem but I remember calling a Porsche dealer a couple of months ago to ask if the 4.8 was better build and they said it didn't have any issues like the 4.5 had with the cylinder walls. So I checked again why my car had a new engine and indeed, also mine had scored cylinder walls at the time.
Some people say it happens because of starting the car in freezing conditions but in Belgium, it doesn't get that cold like in Alaska or Scandinavia. I suspect just a bad build engine or the wrong use of materials for the cylinder walls.
It would be nice to know how common this is on the 4.8. I am very interested in how a car works and why an engine can fail so I would like to know who has or had an Cayenne 4.8 (S, GTS or Turbo) and if you ever encountered this problem.
I've been searching for a 957 over the last few months and I think i finally found the right car. The car is being sold through Shift.com and has a 200 point check. The reports look good, except for the minor cosmetic damages. I followed up with the service centers to see if the car is in good shape and everything checks out. One concern, is the mileage being around 50k. I was told that I should expect to replace the drive shaft over the next few thousand miles. Porsche service quote $2k for labor and parts--does that seem reasonable or would be closer to half of that at an independent service center? Also, this would be my first Porsche. Until now, I've been driving BMWs, so maintenance was covered. What can I expect in maintenance costs for 50k,60k, 70k?.. for you Orange County members, any good recommendations on an independent service center?
FWIW, this car seems like a good deal with low mileage and no visible problems--at least to me. The more important question is, would you guys buy this if you were in the market for a 957? Any concerns?
Thanks in advance!
