Dead Battery access

After not driving my Cayman S for a few weeks I found the battery completely dead.  I tried to gain access to the frunk by the method in the owners manual (pulled out the positive contact in the fuse box) but could nto get the frunk release to function.  I have done this before & got into the frunk by this method & was able to charge the battery & get everything back to normal.  I obviously did not expect to leave it so long before getting back to the car.  I did find that I'd plugged in a USB charger which had a light in it.

Third Brake Light

How is the third brake light accessed? Its just not obvious to me and would prefer not breaking anything.

Proper procedure for fastest Launch Control.

Hello! Everyone

I hope to find some knowledgeable answers here, this is the question which gets confusing very quickly.

For a 2018, 718 base cayman with PDK and Sport Chrono package, what is the best procedure to get the fastest 0 - 60 mph launch? The issue comes when not knowing what combinations of buttons to press.

**For all intents and purposes let's considered that you are already depressing the break, floored the gas and the "Launch Control Activated" is already showing on the dashboard. Lets also considered that the launch will be done on a dry, hot surface.

Does the DME need to be programmed when a new battery is installed?

Hi,
2016 GT4 question. What is your experience with battery life? Replace at failure, or on time? More importantly, does the ECU need to be programmed when you change the battery. I know some models of BMW require an ECU update, or the new battery is not recognized as “new,” and the alternator charges it as if it’s still the old, failing unit. 
Thanks,
John

How PSM works after traction is lost

I have a question about Porsche's PSM.  I have read the manual and understand what PSM does to help stabilize the car in a turn.  The manual does not discuss what PSM does, if anything, once the car has become unstable and has lost traction.  For the sake of discussion assume one has hit some loose material or ice at the apex of a left hand turn and the car's longitudinal axis is now on a radial line while the center of gravity of the car is following a tangential line.  This would happen extremely fast and the car probably would already be sideways before PSM kicks in.  The question is doe

Key remote not working

Hello Pedro,

I went to the store a few days ago and upon returning to my car the remote would not unlock the doors or hatch/trunk. First thought was a dead remote battery. Upon returning home, I tried my second key, also a no go. So I checked batteries with a multi meter. Both at 3.4 volts but I changed the primary key battery anyway with a tested new battery. Still no results. All doors lock and unlock with the key, the alarm sets, and lock and hatch releases function normally.  Can you advise a possible fix?

Best regards,

How to Clear check engine and airbag warning lights after installing longtube headers

way out of my league but I have been told I can "flash" the system with a computer??

Took it to dealer and they schrugged their shoulders

Auto start-stop function

My 2014 Cayman S Auto start-stop feature seems to work normally most of the time. However, sometimes when the engine is at normal operating temperature and with the air conditioner off and the auto start-stop function button engaged, the engine will not shut off when the car is stopped at a stoplight with the transmission in neutral, manual transmission, and sport button not engaged. Does anybody else experience this and or know what's going on, in other words why doesn't it shut off when the above conditions exist?

Trying to figure out my new to me Bose CDR30 with PCM2.1

OK, I've tried searching. A lot. But I can't find the answers to a couple of questions and they don't seem to be addressed in the Owner's Manual either. The stereo manual itself either doesn't seem to be available, which I think is odd. Both my BMW and Jaguar came with printed separate manuals just for the stereo.

I have a 987.1 with the 680 Bose High End Sound Package, and the P23 PCM 2.1 w/ Extended Navigation

PCM 3.1 in endless reboot

My PCM has been in an endless reboot, and I'm likely looking at a full PCM replacement. I am able to source a replacement unit independently, however I don’t quite know what the procedure would be for coding. Would this be something I’d have to take it into a dealership for, i.e. recoding the unit to the car? And would they be none too pleased that I’m bringing in a 3rd party replacement unit instead of buying it new through them? Thanks to anyone that might be able to provide some information on this!
