  1. Codes cleared, you did a highspeed run down the A3 or A5 and all is well?????
  2. I've been to just below the headlights before and very slow. Definitely wouldn't recommend going any higher. My low tone horn failed soon thereafter but the high tone still works fine, that was about 2yrs ago.
  3. Congratulations on finally fixing that problem. A lot of work but you've fixed a lot of weak points which will contribute to long term reliability. I can't remember, do you have stock air filters? A more open filter can let some of the intake and/or Turbo whistling noise through.
  4. I may have been mistaken quoting the diagram number Lewis. Are you saying that Porsche has chosen to only to only sense off of one Turbo? On my Audi with ME7.1.1 both wastegate hoses go to a tee then onto the N75 and both Turbos have a sense line that tee's then goes onto the N75.
  5. Great discussions here, yes, a plugged or disconnected line should and will cause an quick overboost before the ECU shuts it down with a fault/limp mode. Keep in mind that lines (picture above) 10 and 5 (from each Turbo) go to a Tee before connecting to the N75 valve. So line 10 may be Ok but line 5 may be the problem. This is where my portable Snapon Bk6000 video scope saved me on my Audi.
  6. The N75 compares the ambient air to the compressed air from Turbine side (cold side) and adjusts boost accordingly. If you have a leak in the line going to the cold side from the N75 the sensed pressure will be lower than actual and the Turbos will try to overboost for a few seconds then the ECU will detect it, through the MAP sensor I think and will cause limp mode or just plain reduced boost. I had this happen on my Audi RS6 which also uses Motronic 7.1.1. Had just did an engine pull & replace, then had a custom tune and I started asking the guy for a tune with less boost. He gave
  7. Very similar on the 955 to the 957. Scroll down and download his pdf. I installed mine under the plastic trim panel so you don't see the can but it does catch a fair amount of oil that would otherwise be coating the Intercooler, throttle body, intake manifold, and turbos.
  8. Oil isn't good but it is normal. Most of the oil comes from the PCV vent system and not from the Turbo seals. I found the delamination in my Y-pipe also a couple years ago and happened to find a new old stock IPD plenum to replace it. I don't think I would ever pay full price for the IPD product, it is better made and better flowing than the stock plastic pipe but not that much better. With that said, the stock plastic Y-pipe is pretty cheap to replace. Also, I installed two Oil catch cans in the PVC system to catch some of the oil going to the Intercoolers and intake, they do make a huge
  9. I'm at 91K on original pumps ('06 CTTS). Probably around 100K I will do the pumps/filter as preventative.
  10. Sorry, way late as I have been gone for a couple of months but yes, that's it.
  11. 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 fo
  12. 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
  13. 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.
  14. 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.
  15. 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 know
  16. 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.
  17. I can't answer that for sure but I'm pretty sure they're not pre-wired.
  18. 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
  19. 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
  20. 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
  21. On my '06 CTTS the plug in the Boot isn't switched (always Hot) and the one I use for my Trickle charger.
  22. 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.
  23. 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?
