Welcome to PCA's source of expert advice, where our PCA National Technical Committee experts answer your questions about all things technical.
I own a 2006 997 Carrera S Aero and the problem just about every older Porsche has with the black foam spitting out the HVAC ducts. I’ve watched videos on how to repair with new foam tape on the blending flap but some people say to do one flap or are there two flaps to recover. I know the two ways to get to it by through the heater core compartment and through the center of the dash. Any advice on one or two flapd

I just joined the PCA through the test drive program. I’m 57 yrs old, recently retired Correctional Lieutenant, and have saved up 52K to buy my dream car which is a1980’s series 911 Guards Red, Targa wide body with a whale tail. Unfortunately, a 930 Turbo is out of my reach, so I have to go with a 930 Turbo “look”. I’ve also allocated 2k a month for upgrades and repairs over a 3 year period in an attempt to bring the car up to an 80-100K car. So, if I buy an original car and modify it, will t ...

Sunday 11/02/2025 | 2018 | 718 Boxster | Electronics
I just purchased a 718 Boxster. It did come with 2 fobs, but once I got it home it seems one of the fobs is not recognized. The buttons would sometimes work to lock, and unlock, but the fob will not start the car. I replaced the battery, but that didn't help. After awhile the alarm will start going off if I use the remote in any way. I noticed the red light on the fob just keeps flashing for a period of time. I eventually can stop the alarm, but I am afraid to use that remote going forward. I ...

READ ANSWERLCD on center gauge is dimming to nothing, where is the problem?
Friday 10/31/2025 | 2006 | Cayman S | Electronics
The large LCD in the center gauge began dimming towards the end of a 4 hour drive last night. This morning it worked fine again, just to turn all the way off shortly after. It doesn't have the typical "bleed" problem that these LCDs get, it just simply fades to nothing. Is the screen failing? That seems odd since it was bright and normal again this morning after the initial issue last night.

READ ANSWERAlternative Fix for PADM Failure?
Wednesday 10/29/2025 | 2014 | Cayman | Suspension
My '14 Cayman has the dreaded PADM failure. I understand the failure causes the mount to revert to the street/"soft" suspension and most report no noticeable difference in handling qualities. I just got an estimate for replacement of the mount and it is $3600! The repair shop says there's a new, upgraded mount and that part alone is $2500, but it's on backorder. I've come across numerous reports of obtaining new sensors from "Poporacing" in China and they are relatively inexpensive at $19 ...
