  1. jpflip - In my case the culprit was cable #28 on the parts diagram, which runs from the alternator to the starter. But for good measure and to avoid future concerns, I also replaced #36, which is the engine ground strap, and because my car is blessed with a Tip / paddle shifter set-up, #24, which crosses over the transmission on Tip models. Cables #17 (MT) and #19 (TIP) are the long cables that run up to the distribution box below the battery in front. I didn't bother to replace this one (but have a new one on the shelf just just in case) because I didn't find a significant voltage drop on
  2. This is a belated reply to document the resolution of my car's low voltage problem. Replacing the cable between the alternator and the starter entirely resolved the issue. As JFP correctly noted, apparently the cable I replaced had developed internal corrosion causing an increase in resistance. It's frustrating when a Porsche dealer tells you everything is okay when you know it isn't. Now having the requisite voltage flowing throughout the vehicle is a beautiful thing.
  3. Just to clarify, you mean either the exhaust inlet or the exhaust outlet?
  4. Wouldn't I be seeing exhaust smoke (i.e., burning oil) if the rings are going? Not sure how to peek at the intake side of the turbo. Would this be looking in opening where the exhaust manifold mounts to the turbo unit? Or somewhere else? And if it gets to the point where a rebuild or replacement is necessary, who are the preferred specialists for performing a rebuild? Or am I just better off buying a reman unit and going with that? It's a stock K24 unit.
  5. While recently changing my spark plugs, I discovered about 1/4 cup of oil collected in the lower driver's side boost (pressure) hose that attaches to the intercooler. Didn't necessarily appear to be fresh, but not sure. I change my own oil, so I know with certainty that the engine has never been overfilled, at least during my ownership. Are there any diagnostic procedures I can do identify the possible culprit?
  6. Really depends on your planned usage (e.g., track, weekend fun, daily driver, etc.), but IMO, make sure it's up to snuff in stock form (i.e., maybe fresh coils and plugs, etc.), and then start with a software tune of the ECU. If you don't mind exhaust drone, many owners do an exhaust next. After that, the possibilities are pretty much limitless (or limited by how much you want to spend). You'll love it!
  7. Thanks for the response. When you say "run a voltage drop test across both primary cables", can you please be more specific (auto electric beginner here)? Do you mean the cable from the alternator to the starter, and the cable from the junction on the transmission up to the power distribution box? If so, I need it spelled out for me. Which terminals on the alternator cable should be used to test the voltage drop (alternator to starter, battery positive in engine compartment to starter, starter to junction on transmission, or alternator to junction on transmission - there's three primary c
  8. My car's two year old battery failed about a month ago, and I've been chasing electrical system issues ever since. The 996 Essential Companion book says you should see 13.8V across the battery terminals with the engine running. I was seeing low 13Vs or high 12Vs, so I started the search for the missing volts. Obviously, the battery was replaced with a new AGM battery with the correct Ah rating. Next step was to replace the voltage regulator. No significant increase in system voltage at the battery. So next, I installed a remanufactured Bosch alternator. This seemed to help. Upon start-
  9. There have been some part number supersecessions, but all the X50 and GT2 models share the same muffler. It's difficult to find used factory X50/GT2 mufflers, and there are many sellers out there misrepresenting what they are selling. The factory part number on the turbo mufflers (both base model and X50/GT2) is stamped on the bottom side of the muffler case on the passenger side of the muffler. Many sellers mistakenly identify the muffler part number by claiming one of the numbers from one of the heat shields is the muffler part number. This is not the case. The bas
  10. Porsche NA is belatedly recalling 2003 - 2006 Cayennes to repair fuel pump flanges that cracked and started leaking. The press release is attached, but I didn't see anything on the NHTSA website yet other than a complaint about the problem. Porsche_Cars_North_America_Statement_Regarding_Cayenne_Recall.pdf
  11. I'm assembling my freshly repainted front bumper cover. I ordered the protective films shown in the parts catalog that are associated with the front bumper cover (#18 and #22 in the parts diagram) and easily figured out where #18 goes. I can't figure out where the two #22s go - on the cover itself, or somewhere on the body? I've attached a picture of the actual part and for reference the parts diagram showing it orientation. Any help appreciated!
  12. My spark plugs are due for a replacement, so it might seem like a good time to throw in a fresh set of coils in order to avoid potential duplication of labor down the road. My engine presently has no coil-related DTCs, and currently has the "20" version of coils in it. In perusing the Porsche parts catalog, I note the coils for the 955 Turbo Cayennes have been updated twice since my prior coil replacement, and are now number 948 602 104 22, with "21" coils being offered for a period of time. The equivalent Beru (OEM supplier of the Porsche packaged coils) coil part number is ZSE 012, but Be
  13. To close out my experience, I ended up having both fuel pumps replaced and everything is perfect again. I'd say for anyone experiencing a strong fuel smell outside the vehicle near either rear quarter panel, plan on it being fuel pump related.
  14. Belatedly, but for the record, I ended up having the PPI performed by Eurosport Automotive in Arvada, CO. They did a thorough inspection, charged a very reasonable fee, and based on their positive report, I had enough confidence in the car to drive it the 1,400 miles to its new home. An excellent drive with the car performing flawlessly.
  15. This is a stupid debate, but having just personally installed an aftermarket exhaust on my X50, factory fitted with X54 tips, I know exactly how the optional stainless steel quad tailpipes are designed since I was just working with them. And one side is not closed off. The tip connects to the muffler as a single pipe, and then splits into the two sides of the tip, both of which flow exhaust gas. So they're differently cosmetically from the base singles tips, but exhaust gas does come out both sides of the X54 tip. They do say the X54 tips are worth an extra 6.3HP . . . just kidding. If I
