READ ANSWERon my 2014 Cayman S I've had intermittent power steering loss. Most times only for a moment, but recently completely out with warning on the dash. Shop checked and found code for short/open circuit in the power steering motor. My question; is the power steering motor integrated in to the steering rack where the motor can be replaced or does the entire rack need to be replaced?

READ ANSWERWill regular use of the "stop/start" function reduce the service life of the engine bearings?
Thursday 10/09/2025 | 2016 | Cayman S | Engine
I recently acquired ths car as a CPO. The dealer had the "start/stop" feature turned off when I purchased the car. I've talked to a few other Porsche owners with cars that have this feature, and they, too, have it turned off. In a perfect engineering world Porsche would have beefed up the bearings before the US government required this feature to account for the anticipated additional wear. Did Porsche? I get no particular joy unnecessarily burning fuel at a stop light, but I want this e ...

Monday 10/06/2025 | 2006 | 911 Carrera 4S Cabriolet | Body
I’m having trouble installing the front spoiler (photo below). The valence is flexible, so it simply bends upward when I try to push the tabs into the slots. It is the correct part, and the slots all line up. Any tips?

When I activate the fan in the deck lid to stage 1, there is no movement. When I activate it in stage 2, it spins but sounds really rough unlike before. This happened after a 5 hours drive in 80 degrees. I removed the fan and it spins freely.

READ ANSWERI removed my passenger door handle to replace it with a carbon fiber one, when the door closed it will not unlock mechanically. I’ve tried pulling the door cable and hear the actuator engage, but it still does not open. I tried the key fob, disconnecting the battery, and the electronical lock inside. They all do not work, any suggestions?

READ ANSWERHi there - I have had to replace the driver's side convertible top transmission as a result of the plastic drive wheel breaking.
Tuesday 09/30/2025 | 2006 | Boxster S | Other
The installation was straightforward and the top is operational again but since installing the new CT transmission I have notice the passenger side of the clamshell is not flush with the rear quarter panel on that side, while the driver's side is flush. It is quite noticeable when the top is down (the clamshell is about 1/4in above the pax side hind panel when the top is fully retracted - see pic attached) vs when it is up (about 1-2mm above the pax side panel and barely noticeable). The od ...

I have to replace my lift side turbo . Is at the dealers for repair.. when they pulled the turbo it was a K 14 not a K 25 turbo model.
