hahnmgh63 replied to bayernstern's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)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.
I can't answer that for sure but I'm pretty sure they're not pre-wired.
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.

hahnmgh63 replied to PaulH's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)On my '06 CTTS the plug in the Boot isn't switched (always Hot) and the one I use for my Trickle charger.
You need to dissassemble it from the back side.
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.
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?
As I said, use a hard plastic spatula if you don't have a set of trim removal tools (basically plastic spatula's in different shapes and at different angles) so you don't scratch anything. Start at one side and slowly work your way across until the whole panel pops off. Here's a pic of the camera and trim piece. Not mine but found it on a Google search. Trim piece just pops back in.
If it's like the '06 CTTS then you have to remove the rear trim panel, use plastic spatula's so as not to scratch, the fasteners just pop out. Then if your mechanically inclined you can take apart the small little jackscrews and clean and lubricate them. Worked on mine, been going on 3yrs+ since I took mine apart and cleaned and re-lubricated. Use a good quality grease like a synthetic as they tend to hold up better against moisture/water.

Makes you wonder. Many of these options are more expensive that stock or about the same. Wonder if the .21 versions are any better? As it goes Porsche is changing its part number for revisions but if you check Beru's site they've had the same part number all along? Makes you wonder if they've really improved them much at all as it seems like they're regular failures still happening on every version after 3~5yrs of regular service. I also see the Spectra Premium label? A Canadian company although I don't know if they actually manufacture them in house. I just don't want to end up with a Chinese product that lasts 6mths or less for a few dollars savings. http://www.stylintrucks.com/parts/spectra_oe_replacement_ignition_coils/SPEIG93434/spectraspic793-.aspx#
I've got an old 2001 Audi TT 225bhp that I use as a commuter. For that you have the Beru coils or Hitachi. All the forums say don't use the Beru, use the Hitachi coils. I've had a set of the Hitachi coils in there for over 12yrs as the original Beru coils failed after about 3yrs. Just saying, Beru coils have a bad reputation on other forums too, but they manufactured enough versions of the 1.8T motors to use more than one OEM supplier so there is a choice, wish we had a choice.
After pretty much going up the number chain on the revisions Porsche jumped from .09 to .20, then .21. I have fairly new .09's in mine but it is pathetic that after all these revisions that there are still problems.
