Apparently the wiring harness for the vehicle now has problems. Everything worked when I dropped it off except the Xenon headlamp. They swapped the modules and ballasts and determined the module was a culprit. Replaced module with a 3.5 week wait. After putting in a new module, the high beams on both sides stopped working. Eventually found that "someone" put in a 30A fuse where there should've been a 20A fuse, and flipping on the high beams fried the wire. Wired directly, bypassing the fuse and now the high beams work. 🤨 When he pulled it out today for me to pick up, the wipers aren't working anymore. Same deal, had to wire directly bypassing the wiper fuse. 🤨 Time to sell this pig.
No insight on how the high beam wiring goes?
P0441 is the vapor purge system. On my 06S theres a line next to the throttle body along the drivers side of the intake manifold that had to be replaced. Theres a good youtube video of how to do that part. I had to cut the old line to get it out as he does in that video, that rubber hose did not want to budge after that many years. 2187/9 is a oxygen sensing limitation, which could be caused by the purge solenoid/line problem, so I would definitely fix the P0441 first and see what comes back. However it could be fuel related too, fuel pumps or injectors, could also be a vacuum/PCV leak, or maybe even the gas cap and oil fill cap. It happens as it drops into closed loop once its warm and the Oxygen sensors see something amiss. They are not used in open loop immediately after startup, so that's why it runs normal when cold and not when warmed up.
Drivers' side Xenon headlight stopped working a while back, and both high beams were working along with the turn signals. 06 Cayenne S. Couldn't find a cause for drivers' side headlight Xenon beam not working, despite testing a new light, and Dealer said it was the Module. Waited 3 weeks for a new module to come from the Fatherland and get the car back home, and see they've set the headlights to be always-on anytime the car is running, and then found out that the high beams on both sides are not working at all now. Dealer thinks that some aging wires with crumbling insulation in the passenger headlight shorting are the cause and recommends a new passenger side light, as he doesn't think they make replacement wires to go in there. Now I need a crash course in how the high beam signals ground through both lights, because I don't understand how they worked when I pulled the car in 3 weeks ago and now don't.
Tested another xenon headlight that was known to work, issue remains. Put back in the old harness wiring to test that, problem remains. Nothing to do now but let the stealership look at it.
I'm not a huge fan of the tiptronic but I've had zero issues in the 88K I've put on it since I bought it at 98K. I just change the oil once a year or 10K. Coil packs go out about every 3-4 years in my experience. Its a hefty expense to do them all at the dealer, but not as hard as it looks. You can do them yourself.
In my case it has usually been a lack of tools and specific knowledge of the car that has cost me the most money since I bought mine at 98K mi. I can rebuild a chevrolet but not this thing. Fuel pumps will go out, have they been replaced? I also had a DME failure that cost me big $$$. My water pump slowly died, didn't leave me stranded. Fuel pumps did. Most of the other little things I can do myself. I wish I had bought a Durametric when I first got the car too.
Mine does it once every couple months or so. 06 S.
Unfortunately the headlight i have was a brand new factory Porsche lamp that was replaced after a minor sideswipe accident cracked the original, about 2 years ago now. Seems quite unlikely the brain inside the assembly would die after 2 years.
So tonight I took it back out, forced it into the assembly unit and I can get everything to work except the Xenon and the directional Xenon. High beam and turn signal do work. Anyone have any ideas, what about a continuity test on the harness connector? The old connector had been giving sporadic/sputtering light up of the Xenon last weekend when I pulled it initially, when being forced into the assembly, not constant light-up.
Yes even aftermarket Xenons are $700+ and this is not a good option. Pelican Parts may end up sending me another, but I am going to take it apart again and force it to seat first.
Factory as far as I know, which i thought were xenon HIDs, is there a specific car RPO code to check to confirm
I don't let my 06 S go that long on oil, about 10-15K for oil and filter. I pulled my air filters to check every time and they can go forever. I've only needed to do it once in 6-7 years.
There are 4 10mm bolts holding the tray in place, but even with their removal the whole tray doesn't come out, its blocked on the left and right by the body structure. However I was able to get it loose enough to get the harness connector replaced. Unfortunately this didn't solve the problem and the drivers headlight will not turn on at all. Before, I could force the old connector to seat and the main light would come on intermittently, telling me it had to be a connection issue, but there is a tiny bulb to the outside and below the main bulb (3 in the diagram above) that was always on whenever the lights were turned on, so I was at least getting some connection on some of the pins. Now, with the new harness, the tiny light (3 above) on the headlight assembly that is just below and to the outside of the main bulb does not come on at all, and there is no response from the main headlight assembly whatsoever to being pressed in to the connector and held in firmly, when the lights are turned on. I was able to remove some of the vanity covers to get my hands around from behind and make sure it was pressed in all the way once it was in the car too, but no luck. I did double check the part for the harness connector, its the factory as best I can tell. I'm pretty sure this idiot dealer will stick me for the charge of a brand new Porsche headlight assembly, but I don't know what else to do.
