CEL came on, no missing or other noticeable engine anomaly.
El cheapo ELM OBDII reader produced these codes: Was able to extinguish CEL.
P3104 Intake manifold air control solenoid - short to positive
P0104 Mass or Volume Air Flow "A" Circuit Intermittent
P0204 Injector 4 – circuit malfunction
This suggests an intermittent wiring short. Any ideas on where such might have occurred?
Thanks in advance
Hi Porsche Gurus
I’m trying to troubleshoot a little issue I have that just my drivers door courtesy lights (and drivers sunvisor light but not sure if that’s different issue) don’t work, both the red and white ones and only the one door(rhd car)
now ive checked the common things like all the fuses and the wiring to see if they were damaged or corroded but they seem fine,
The one thing I would like to check but can not find any info on is where or what is the switch or sensor that tells the lights that the door is open to turn the lights on?
If I can find that then that will at least eliminate all manual fixes that I can think of unless any of you have come across this before, if it’s something simple and I look like a fool for not thinking of it then I’m happy to be a fool as long as the lights work:)
any help would be much appreciated
Im working on a unique porsche project and as part of it im looking to use the current (>2016) generation 95B Macan LED HeadLights.
What im looking for is the Wiring Diagram from the service manual program, so i can trace what needs to be connected to where relative to my 997.1 wiring harness.
Yes, im aware this will be difficult. Im not looking to just plug and play.
I already have all the wiring for the 997.1 and 997.2 cars (and a few others)
Can anyone help
I just finished installing a factory tow package on my 2009 Cayenne. When I hook up to a trailer and test, everything works except for brake lights. I checked for power at pins 3&9 on the 7-pin and only have power present there with blinker and not brakes. I've check all fuses related to the tow package (1,3,5,19,&41) and all are good. I tested the trailer on another vehicle and the brake lights work. Since I don't have power to those pins, the issue has to be with the Cayenne. Do I need to have the computer flashed if I am not using electric brakes? The trailer I will be hooking up to has surge brakes, so I didn't think I needed to visit the dealer.
Any assist would be greatly appreciated!!!
Not sure if it makes a difference, but when I purchased this car, it had a Curt hitch with a flat blade connector in the back compartment. I didn't trace out and remove this wiring, only the hitch.
