I have it written down, i'll try and dig it out, but they will be different depending on model.
Yeah, that seems to be what it is boiling down to. I will try and replace my rear end control module this summer and then re-do the 2 mosfets and 6 resistors and see what happens. I'll report back. I can help you find the part numbers, why do you believe that you need new exterior antennas?
The module is a little difficult to get to and even harder to install back. I am not sure if there is a guide online, but there should be, i'll try and look.
As you can probably see from this thread, i had the same problem, My dummy key always works, but my handles stopped working. I replaced the MOSFETS and MELT resistors and then everything started working again. But, they blew again and i replaced them a second time! and guess what they went one more time just last year, i have not replaced them for a third time because something is blowing them out after a couple months of use. I am going to investigate when it take it out of storage probably in the fall. My guess is rear end control (comfort) module (I have heard these are known to fail), tilt sensor, or passenger compartment monitoring sensor. Kira Langolf: The reason it works when you press on the rear hatch entry handle is that when you do that it sends almost like a wakeup command to the KESSY module and then your key fob will work. My money is on the MOSFETS and MELT resistors, give it a go and go from there!
Believe it or not, looks like mine have blown again! This will be the 3 time in less than 5 years! There must be a short or something causing the issue...............
I had the same problem last fall. I ended up replacing the hood latch cable, front bumper needed to be removed and both front fender linings.
I have a similar problem that I have been working on for years, except mine is 34 on driver side fuse box. I would trace fuse 22 to see where it connects to and go from there. There are wiring diagrams online.
Brit6 replied to clarksongli's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)Loren, are you sure? I think he is looking for the 955-618-036-05 (CONTROL UNIT- IMMOBI) Part Number 1 on this diagram? http://www.autoatlanta.com/porsche-parts/hardparts.php?dir=9PA-03-06§ion=901-04 clarksongli: Let me know if you get this done, I have heard that once you change the KESSEY Unit, you might have to replace other components to work with the new KESSEY.
Hey markthis, the images in the first post of this thread are still working. Can you see them? Let me know if you still need more help!
I would say the rears as the power is more in the rear (62 per cent to the rear,38 per cent to the front)
I am going to say that possibly my passenger interior monitoring sensor has a short, I have had my heated seats tested at the dealer and they are all ok. My fuse #34 on the drivers side fuse panel keeps blowing (sometimes once a day, sometimes once a week, etc) (34 Passenger compartment monitoring, seat heating 5 Amps)
I changed the 2 FETs on the weekend and all the door handles, and the rear bumper are working again. Now we will see for how long they will last.
Thanks, im going to go try it now, will report back after.
Brit6 replied to colinmartin's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)The problem with these is they break and most of the time you actually have to replace the piece that is under the carpet which snaps into the top clip.
In the tutorial you have these specs: Red lead on SOURCE (right leg), black lead on GATE (left leg) = OPEN CIRCUIT Red lead on SOURCE (right leg), black lead on DRAIN (TOP or back pad) = .5V to .8V Is that the results of good FETs or leaking FETs?
