I’ve had this little drip-drip-drip on the front floor of the Cayenne for about a year.
It only seemed to happen after hot weather and lots of aircon use.
It never seemed to be a problem.
Just goes to show how wrong I am at times.
hashtag epicly wrong.
Long Story Short
The occasional drip drip (onto the drivers foot and also sometimes passengers foot) slowly soaks into floor mats. Overtime this is trapped under the floor mats in the hugely spongy underlay.
This leads to water damage and corrosion of some electrical wires under there. These corroded wires will eventually (incorrectly) send bad signals to the engine computer which then lights up the dashboard like a Christmas tree and scares you half to death: warnings of Brake Proportioning, ABS Failure, Key not recognized and some others.
But don’t panic – help is easy for anyone with some basic tools and the urge to fix it themselves (rather than the $1800 I was quoted by Porsche)
It took me a lot of trial and error to find these culprits but it’s done and I managed to video each part. I will edit a video together showing how to do it. It’s really very simple. This definitely seems to be a design flaw from the Porsche Peeps and hopefully my solution will help some other folks out…
UPDATE – I found the DRIP DRIP DRIP and fixed it.
I just stumbled across this video by a German youtuber called Techben: I love his videography style and (obviously) his awesome Porsche 911E Targa.
“In meinem heutigen CINEMATIC-VIDEO zum Porsche 911E Targa, zeige ich was mit der Sony a6300 (Kit-Objektiv) in Kombination mit der Inspire 1, GoPro Hero 4 und Edelkrone Slider so möglich ist.”
“In my current CINEMATIC-VIDEO to the Porsche 911E Targa, I show what is possible with the Sony a6300 (kit lens) in combination with the Inspire 1, GoPro Hero 4 and Edelkrone slider.”
Is there a midget with a hammer hiding inside your Porsche Cayenne (or VW Tourag) gearbox? Does light acceleration make your car twitter like a flock of angry birds? Chances are it’s the Porsche Cayenne Drive Shaft support failing – This part is basically a rubber support that is in the middle of the driveshaft. This is a well known piece that wears out on Porsche Cayenne (and VW Tourags) at around 100k miles. On mine it suddenly wore out quite spectacularly, while pulling away reasonably hard into traffic there was a loud *BANG* and then *KNOCK KNOCK KNOCK KNOCK* which sounded like it was coming from inside the gear box housing, or where the gear change lever is.
I was quoted $2000+ to fix this from a local Porsche Dealer so decided to do it myself. I’m a noob mechanic and this is the first mechanical thing I have ever undertaken with this car.
This “Porsche Cayenne Drive Shaft” fix was a simple procedure (even for a mechanically inept buffoon such as myself) and took me about 40 minutes, and that is including reading instructions, trying to records this nonsense and (obviously) spending many minutes trying to squeeze my fat belly under the car….
I don’t work for Vertex nor do I have any interest – but it fixed the problem and was easy for a fat fingered mechanically inept gray haired old fart like me to install!
You can buy the part from VERTEX and will need to buy some ramps (about $40) and an angle grinder (also about $40-50) and then a few basic tools (couple of spanners, some wire snips and a razor blade to trim the old rubber off the center support on the drive shaft).
I just stumbled across this wonderful video on YouTube, a bunch of guys driving various Porsche 911 models around the beautiful curvy Austrian roads. With a only 35 views and only 2 likes? This video needs some adverting, it’s wonderful!
I know nothing about the YouTube channel Unique 911 Driving but I’m subscribed and hoping for new videos soon. Described as “…a group of Porsche 911 enthusiasts, who love this car and spend quality time together to get out and drive. Here we share some of our experiences.”
I’m looking forward to the next 911 adventure. 🙂
