I came across this old post in a Google search and thought I'd provide an update. The Porsche part number for the adjustable linkage is 986-424-931-06 and is available from Pelican Parts for about $250. Numeric Racing makes an all-metal version for $130. The adjustment procedure for the adjustable-length linkage is available in the Porsche OEM Service Manual.- 2 replies

U0404 - Software incompatibility with transmission control module - signal implausible. A U0404 code on a Porsche 997 indicates an issue with the Electronic Shift Module (ESM). Specifically, it means the Powertrain Control Module (PCM) or Transmission Control Module (TCM) has received implausible data from the ESM. The ESM itself could be malfunctioning, sending incorrect data. The Transmission Control Module could also be the source of the problem, either by not processing the ESM's signal correctly or being faulty itself. Damaged wiring, loose connections, or corrosion in the wiring harness connected to the ESM can also cause communication errors. Some deeper diagnostics are going to be needed to decide how to proceed............. -
Welcom to RennTech Before considering replacing ANYTHING, first do some diagnostics: Using a Porsche specific scan tool, check for any pending codes, check all four O2 sensors for function and voltage readings, check the MAF for voltage readings, and run A/F ratios; then and only then will you have the information about what, if anything, needs to be addressed.

Back in 2011 a previous owner of my 1999 Boxster replaced the bad 2.5 with a 2.7 from a 2001 Boxster. It appears to be a professional installation (or at least carefully done), and it has around 35,000 miles on it since then. The ECU has also been reprogrammed (by ECU doctors) for the 2.7. However, it smells like it is running rich and I fear will start fouling out spark plugs. I'm planning to replace the two upstream O2 sensors because those are responsible for controlling the air+fuel mixture. My question is whether I should buy O2 sensors for a 1999 Boxster with a 2.5, or a 2001 Boxster with a 2.7. I've checked a couple sources and the part numbers given for each are slightly different. What is community thinking on this?

That was it thank you so much!

I have a 981 which I retrofitted a pcm 4 I want to add a camera. I have an oem camera and harness I have wired it but I do not see the option in the pcm to activate backup camera. Where do i activate it? -
Hello Loren! Can I please request a 5-digit code for my Mercedes Benz Becker Classic BE2011 serial number T1025315 radio, usual story (Mercedes dealer themselves disconnected the battery, now say they can't find the code anywhere!) Thank you in advance
-
Aha, that would have been easier! A pair of hose removal pliers will be a great addition to my toolbox. Thanks! -
Try 8237

I would be checking the power supply wire to the actuator to measure voltage and voltage drop.

Hey everyone, I’ve been having an intermittent issue with the frunk on my 2002 996 Turbo. Hoping someone here has seen this before. Issue: When I try to open the frunk using the interior switch or key fob, I can hear the actuator making a noise like it’s engaging, but the latch doesn’t release. This happens occasionally — sometimes it works just fine, other times it won’t open at all. What I’ve done so far: Replaced the frunk actuator with a new unit. Tested the actuator using a Power Probe, and it pulls with noticeably more force than when it’s activated through the car’s system. Given this, it seems like the actuator isn’t getting full power when triggered by the car. Could it be a weak ground, wiring issue, or something in the control module? If so, anyone has the wire diagram? Has anyone dealt with low voltage going to the actuator or had similar symptoms? Appreciate any insight!

Hi Everyone I'm in the midst of rebuilding my 2011 Cayenne turbo's transfer case. I have the newer style Transfer case (1.25in chain) and I bought the internals from AWD.tech. Andrew from AWD.tech told me there's a newer software/firmware for the 2017 (or 18?) transfer cases that had CNG coated plates that I need to make my TC work properly. I have PIWIS 2 but have never used it... can I do the software update directly on my computer or is that a function that only a properly licensed and online PIWIS 2/3 would be able to accomplish? if I am able to update the software, could anyone tell me where or how to do it? I've searched a bit online and in the forum and can't seem to find it if it is out there. i've seen a few people ask how to update modules but no answers -
Like I predicted in the post above, it does indeed just "pull out". But you need to pull on it as if your life (or Porsche) depends on it, while making sure not to damage the bottom connector. It's tough because you need to hold the bottom part, but there isn't enough space to properly grip it. In my experience if you can pull it a fair way up you can then twist and turn it all the way off. Good luck to anyone who is changing this part and is having issues getting it off!
-
Looking at the both sides of the "connector", I'm guessing I should just pull on it until it comes loose. Wish me luck 🤞

Hi all! I'm working on my 2008 957 Porsche Cayenne S and I can't seem to figure out how to remove this brake booster line connector. The part # is 95535557930, it sits in the passenger side of the engine bay right by the coolant expansion tank. It doesn't seem obvious to me, and I don't want to force anything as I'd rather not replace the other end of the hose as well. Any pointers are welcome, thanks!
