READ ANSWERMy 2009 997.2 (PCM3.0) does not have the AUX input in the arm rest. I have recently added a car play board to the head unit. In order to hear the sound from car play I need to choose the AUX input. To do that I have to code the car to tell it I have the AUX option (which, of course, I do not). I have a Durametric pro version. Can I do this, and if so, how? I was hoping to see AUX in the durametrics software and I'd simply switch it to Installed. No such luck!

Thursday 04/23/2026 | 1989 | 944 S2 | Electrical
George, I saw a thread where you say to use a Group H6/48 battery in a 944. When I tried to use that size in my 968, it hit the support structure of the hood, and I had to use a Group 91 instead. Are you sure that ALL years and variations of 944 will accommodate H6/48--particularly when the windshield-washer hose can end up between the battery and the hood? To protect against any acid-leakage damage, I have recently started to use one of those thin "battery mats" below my car batteries. T ...

I believe the power diode that sits across the positive and negative on pins 4 & 5 of the radio’s connector is bad.

The hydraulic rams had to be rebuilt. After installing them the top will not open correctly. There is a one inch gap between the front of the top and the panel which holds the pop up roll bars. It worked correctly before the rams were rebuilt. Is there an adjustment for this issue?

I find little to no discussions of the (what I understand to be) one year production of the hard top targa and was hoping you could assist me in my search for additional information, any tidbits would be greatly appreciated.

Watching Nathan Mertz on YouTube 1974 -1977 Porsche 2.7. He notes the 1976 as the last year you could instal the Targa top unfolded in the trunk, the only way the top should be stored. This seemed the perfect segue to discuss the factory hard top targa. Wondering why, and his thoughts on the matter. I am a first time porch owner, and yes, it is a 1975 Hard Top Targa, abandoned 20 year barn find in the process of restoration. Really enjoy his video's. ...

I get P1691 as a code. Thanks again, Dave I'm preparing to install front brake pads on my 2025 Cayman S, VIN # WP0AB2A88SK261009. In looking over the front pads in preparation for replacement I see that there is no wear sensor in the outer pad. Neither front caliper / pad has a wear sensor in the outer pad. Close inspection of the caliper I can see there is two (2) wires coming out of the protective sheath, on the sensor cable, but I cannot see where the second wire leads.

Called AAA to jump the car and after a bad battery test they installed a new battery. The new battery failed after a few months and a replacement battery was installed. The car started and ran for about 5 minutes and then quit. The car would not restart so the AAA tech attempted to jump the battery several times.

I have replaced all the wheel sensors. ( with Porsche parts) what could cause this intermittent issue? After reviving a dead battery, I've fixed all of the lights (PSM, airbag, etc.) but still have a 'Service now' message with a red exclamation light on the tach. The exclamation point goes away after signaling or using the high beams, only to return a few seconds later. The car is running fine otherwise. Any tips on how to reset the light without going to the dealer?

The cup holder face lid does not close, keeps dropping down everytime I try to close it. Did work, but now it doesn't. Is there a remedy for this that I can do at home? Thanks.
