READ ANSWERI have a leak where the rain is coming in around the passenger kick panel onto the carpet. The head liner is never wet and the sunroof drains have been updated by Clearwater Porsche. Could it be the windshield leaking or something else down in that corner?

I sent in a question before about the problem but never got an answer. Any help would be greatly appreciated.
READ ANSWERWhenever it rains the carpet on the passenger side gets wet. It comes from the rainwater running down the passenger side kick panel. Clearwater Porsche replaced the sunroof drains with updated parts. But the leak is still there. Have you run into this situation before? Could the windshield be leaking? Or could rain be coming in through the Air duct to the odor and allergen filter, which was also changed by Clearwater Porsche. Any help will be greatly appreciated.

Friday 03/13/2026 | 2018 | 718 Cayman | Performance Modifications
I'm planning some upgrades this year. Larger turbo, downpipe, cooler, etc. I am trying to identify the correct spark plug. Everything tells me I need to go 1 step colder. Research shows me NGK 97506 or NGK SILZKBR8D8S. Do you have any experience with this choice? Searching the NGK site doesn't show either of these although there are many places that sell them?

Monday 01/12/2026 | 2018 | 718 Boxster S | Electrical
My driver memory functions don't work and the memory buttons on the door are non functional. Dealer troubleshooting points to a faulty seat control unit part number 970-618-537-13. Not a terribly expensive part online, but the part and labor at the dealer is expensive. Is this module fairly easy to replace DIY and is it plug and play or does it require coding to the car by a shop? Passenger side also has at least one broken switch, so I might replace that switch module as well if I kno ...

READ ANSWERTransfer Case Service for Macans
Saturday 12/13/2025 | 2018 | Macan S | Transmission/Clutch
I have a 2018 Macan S which is AWD. Great car, wife loves it. The Porsche recommended service instructions for this model year include all the usual stuff with regard to oil changes, filters, spark plugs at 20,000, 40,000, 80,000 miles etc. However I saw no mention of service for transfer case oil changes. This seems to be different from previous year Macans 2017 and older where transfer case oil service is recommended at regular intervals, usually every 40,000 miles. ...

READ ANSWERKey Fob Gremlin Issue
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 ANSWERMy 2018 base 718 Cayman calls for replacement of the drive belt at 4 years or 40,000 miles. The build date is 7/17 and it was put into service by me in August 2017. This car now has 34,1xx miles. When last at the dealer for annual oil change/service they told me not to be concerned about the drive belt (or water pump). My understanding is the time is about as important as mileage for this type of maintenance. Which is correct?
Friday 08/29/2025 | 2018 | 718 Cayman | Engine
Most of the details in the question it seems. This a Premier Dealer, Porsche of Ocala, which I assume should know what they are saying is correct. However, it makes me wonder if they do not feel competent to do a drive belt replacement. Is this possible? Also, I purchased the extended warranty from the dealer before the original warranty expired. Do cars that exceed 40,000 miles before the original warranty expires have the drive belt replacement done under warranty? If so, will the extended ...
