    Passenger side window issue

    Taking a chance this question will be answered. Hopefully, it will given I didn’t get a full year from my membership lol. 2001 996 C4, passenger window is having issues. Window drops waaaay down automatically when rolled up. See photo. If window is in the up position when the door is open, it does not drop slightly to close the door and the glass contacts the cabriolet top when closing the door. Then, once the door is closed, the window automatically opens six inches on the up cycle inexplicably. When rolling down, the window squeaks and the rubber seal collapses into the sill and pops back o…

    Help needed, pinouts of PCM for BU camera

    Hi All, I am retro fitting an aftermarket camera into the factory automated pop out on my 2009 Cayenne Turbo S. I have an aftermarket head unit which is the pioneer DMH-WT8600nex. I have successfully integrated it into the Porsche system including the fiber optic and I now have remotely run wires for the new retrofitted pioneer BC-10 camera into the mechanical body. I reconnected the PCM temporarily to re-enable the backup camera pop out and then pulled fuse 55 to reset the system because I couldn't find the setting... I can confirm that it reset and when shifting to reverse the mechanical bo…

    2004 996.2 C4S - Engine Seized. Help?

    I do not know the cause but there is metal in the oil. I had the IMS bearing replaced 4 years ago but sadly the warrantee has expired. I had a 60k mile check up at a Porsche dealer less than 2K miles ago but they missed it and claim to have no obligation. Sad... Option 1: Replace the engine. $25k to $30 is my best guess Option 2: Sell it as is Thoughts? Advice?

    Paint code / car specs sticker

    Porsche use to have a sticker on the inside of the hood which, if I remember correctly had the vin and other identification number for the car & options. Does Porsche put that on anymore - the sticker? My ‘06 had it but not the new 992.2 I just picked up. Tks!

    Apple Carplay

    Recently purchased a 2019 718 Cayman. I expected it to have Apple CarPlay, but when I plug into the USB in the center console, the only option I get is iPad. The car has Bose and Navigation, but not the phone box. Is there anything like a software update available that will enable CarPlay through the center console USB? Sadly, the dealer has not been much help. TIA for any help.

    1996 Porsche 911 (993) Turbo — Alarm/Immobilizer Issue After Water Damage

    Hi everyone, I’m working on a 1996 Porsche 911 (993) Turbo, and I’m currently having a problem with the factory alarm/immobilizer system. The car had been exposed to water, and several electrical control modules/PCBs were affected by water intrusion. I have already removed, cleaned, and dried the affected circuit boards, and there are no obvious signs of corrosion remaining. However, I still cannot get the immobilizer/alarm system to pass its normal initialization. Current symptoms: As soon as I turn the ignition/power on, the horn starts sounding continuously. The lights keep flashing contin…

    Help me identify oil pan bits

    2004 Boxster S. 165k miles. New to me. I found some small, black, plastic pieces (smaller versions of the one in the picture) in my oil filter after a recent oil change, and when dumping the old oil I found a single ferrous metal shaving (no more than a few mm wide). I drained the fresh oil and dropped the oil pan to investigate further. The picture is what I found in the pan. The dust stuck to the magnet came from the drained oil. The strips next to the dime were one piece stuck in the oil pick-up screen, and I'm pretty sure it is a piece of the sealant. The amber, glass-like bits are brittl…

    From a Tiptronic A86/00 to an A86/20

    Hello, and if I may ... Following our first Cars'n Coffee here in my home town, I was forced to put my 986 'on hold' while I decided to fix or replace my transmission. The car is a '97 2.5 with an A86/00 transmission. A search locally has found a low mileage transmission from a 2001 S. A response from the seller indicates it to be an A86/20 transmission. Should I consider this change and what can I expect or may have to also replace with the 'upgrade' besides possibly the TCU Thanks!

    996 Calibration: I'm not smart enough to read what PIWIS is telling me

    My 2001 C2 top has not worked the entire five years I've owned the car, full saga below.* Without all the back story, here's where I am today. When I click "Calibrate," nothing happens and PIWIS 3 returns "Function inactive, end position not reached." The front latch is reset per the service manual, and the clamshell potentiometer was installed at as close to 6.2k ohms as I can get it (about 6.24-6.26). [I rebuilt this engine in my dining room with my cat, 12,000 miles ago—I may not know what I'm doing, but I can follow directions.] Top is in service position. Actual Values / Input Signals La…

    Heater pipe replacement part # 94810606910

    Does anyone have any step by step info on how to replace the plastic heater pipe with the aluminium pipe part # 94810606910. There was an attempt made on a Rennlist posting but no conclusion. The 6 Speed site shows the before and after, but very little about the how, and it appears that the engine was dropped anyway to replace the rear distribution manifold. I don't want to drop the engine, that's out of the question, so any tips would be welcome. I have removed the intake manifold and fuel rail to replace the starter for an intermittent partial crank starter issue. Found an abandoned mouse n…

    Vanishing coolant mystery

    As I mentioned in the other post, my US 996 is back on the road. But. But, there was an interesting mystery: the coolant was way down. As in, down by 3 quarts. The interesting part is: there was none on the ground, there was none in the engine bay (I assume the water pump has the usual weep hole which would cause pretty visible residue and/or spray. There was no coolant in the oil and, as far as I could tell, no oil in the coolant. What's my next diagnostic step? I am at a bit (a lot) of a loss. Thank you everyone!

    996 C2 stalling at stops

    Hello there, I am new to this forum and may not be listing all the necessary information, so please let me know what other information is necessary to troubleshoot this issue. My 2000 C2 stalls when gassing from stop (esp embarrassing at traffic lights), it has 69K miles on it and I have tried to troubleshoot and replaced several parts but not able to pin-point the source of this issue. Happens to it when it is hot (>180 deg) or cold. It seems to have started after the fuel pump change. The following parts have been changed so far (within last 500 miles); - New fuel pump and fuel filter - New…

    2013 Cayenne S 0C8 Transmission Valve Body Mounting Bolts

    After months of research and diagnostics, it was determined that the valve body on my 2013 CS, (207k miles), needed replacing. I have the new valve body but I have also read that I should, (must), replace the mounting bolts. Problem is I cannot find any reference to the bolts on any part sites. No part numbers or anything. I know they are a very low torque value +90* but I a very wary of reusing the old ones. Does anyone know a part number or a source for these bolts? Thanks Shaun
