  1. Sorry, way late as I have been gone for a couple of months but yes, that's it.
  2. First time around I just replaced mine with a cheap $25 Ebay camera and all worked fine. As good or better picture than the original. Then recently the motor for the extend/retract function finally failed. I bought another cheap $25 Cayenne/Touareg license plate camera and installed and all is well. I pulled the back center panel and the right side of the hatch panel where the wiring loom goes. I fed the wiring into the grommet onto the side so it went inside the hatch and was able to hook the camera wiring up inside the rear hatch. The Ebay cameras all come with RCA female plugs and I only found a Fakra to Femle RCA plug but got a male to male RCA adapter on Amazon, gold plated too. Camera is working fine. Originally I found through a friend that had a video business that about 25% of the small 12v camera didn't work on the OEM ~6.5v camera input but most did. Also the Ebay license plate camera comes with a LED light for that side of the license plate illumination and it didn't set off the CAN bus fault.
  3. The fill port is kind of like a periscope tube that goes up into the pan. If while running and warm the oil doesn't pour or drip constantly when you pull the plug start filling immediately. What you want to do is fill it, let it drip as it warms and the oil expands with heat, then plug the filler when it reaches plug it when it reaches 40'C. Once the oil temp passes about 35'C it starts heating fairly quick, especially with the summer temps you're probably getting in Frankfurt. An Aisin specialty company in California said it tolerates being a little over filled but not underfilled. If you cap it at a higher temp it will be underfilled.
  4. If you're talking about the little cone bushing which goes on the passenger side wiper I think I got one for $8 from the dealer. I would never replace an arm without a new bushing, they are Aluminum and Porsche considers them a one time use item as they deform a little upon tightening.
  5. Might try disconnecting the MOST connection from the back and then try to boot it up to see if there is a difference? It would rule out that something else on the MOST bus is the cause.
  6. tebee, what year of Cayenne? The Ravenol or Shell TF-0870 would probably be just fine as they are Transfer case fluids and the manufacturers (reputable) recommend them for Cayenne, Q7, Touarge (Same transfer case). The TSB I have says LT71141 which is a different Oil specification. Can you post a link to the Porsche site? I'm curious why Porsche would recommend the TF-0870 since they sell their own re-bottled fluid in a Porsche Bottle. I do recommend replacing the Transfer case and Front Diff fluids (75w-90 gear oil) regularly as the Cayenne seems to be hard on both of them. Maybe Loren knows if Porsche has a new specification out there.
  7. Yes, I have upgraded two Bose systems from Level A to Level B. Just follow the TSB and make sure the vehicle is on a battery charger. Kind of impractical to just leave it idling as it take about a half hour if I remember right.
  8. I can't answer that for sure but I'm pretty sure they're not pre-wired.
  9. For idle I think your MAF reading is fine. Your Lambda values are close (Equivalence ratio). Not sure what the first two Lambda ones are as the 102.39 makes no sense. Lamda or 1 = 14.7 to 1 A/F ratio, optimum burn. Optimum power is a little richer around 12.8 to 13.2 to 1 which is where a Cayenne on Wide Open throttle will run, we'll call it about Lambda .87 to .90. It would be interesting to see those two Equivalence ratio's on WOT when you're making power. See if your program has instructions to see what the meanings of the Actual Lambda values in the first pics are as they should be close to the same on both banks. The Equivalence ratio reading say S1 which means coming from the first (Wide Band on Turbos) O2 sensor which is what you want, pre-cat.
  10. John, not sure what year you have but send me a PM with your E-mail address and I might be able to help you out. Mark
  11. Also: A dead/weak battery A faulty starter motor A starting system circuit Camshaft position sensor circuit poor electrical connection A faulty camshaft position sensor A camshaft position sensor harness that is shorted or open A camshaft position sensor circuit that has a poor electrical connection
  12. On my '06 CTTS the plug in the Boot isn't switched (always Hot) and the one I use for my Trickle charger.
  13. You need to dissassemble it from the back side.
  14. Congrats. When I did my Coolant pipes and 'T's I replaced all of the small vacuum lines I could fine with Silicone vacuum lines which hold up better against aging and heat.
  15. That is exactly how the '06 camera is, same part number. I just removed the pieces you show there and cleaned them, re-greased them and put them back together. You have to adjust the screws so the cover opens and closes flush with the trim piece. Is there actually a broken piece in there or can it be cleaned and re-greased?
