Question im in new york this is my first year having the panamera and this past week the weather has been around 45-50 degrees i have heard my suspension compressor run for about a minute & then 20 minutes later run for about 30 seconds i checked my bags no leaks so just asking you all does the cold weather affect the suspension compressor? Ive had it fail in the past i dont want that to happen again . I also run a compressor horn on my panamera and ive notice thats been running more often since the cold weather so yea any info on the suspension and cold weather will help thanks
IMO, your system is running fine. Remember, car is actively monitoring leveling, weight, pressure, ambient temp, etc, etc, in all parts of car. Getting into the car will tell car to raise part to level up.
Changing weather will make car inflate more to keep same level in shocks and in air tank.
If you changed the compressor already, along with compressor relay, you should be in good shape. As long as system is not leaking, it should be working within design specs.
If weather gets warmer, I would check for system leaks again at shocks (front and rear), valve block, compressor connections, air tank connections, air lines. If no leaks, you should be set.
If you hear compressor running for 3 minutes, I would starting troubleshooting, but it is designed to work for about 1 minute at a time.

when I replaced my compressor last winter after extremely cold conditions (it was original) I had an option to make it work at -35 degrees for like $300 extra so a no brainer. Is this an option for you? I figured it’s worth peace of mind as I’ll be driving it to Canada this winter for a heli-ski trip and don’t want to be stranded in the boonies.

what do you mean by that extra option what was done?

My Indy told me there was a software option for the compressor (rev G?) that protected it to extremely cold temperatures so I went for it since I was spending $2k already for the replacement. Check with your mechanic he should be able to track this down for you. Good luck Lou!
Seems odd to me that a car designed for use in Germany could not handle cold weather in its stock form. Would really be interested in any more information as to what is included in the "cold" weather package.
I have driven my '14 4S through one Michigan winter -- coldest temperature last year I remember getting the car out in was about 10F. Did not appear to have any issues with the air suspension at that time.
Only issue I have ever had was when I drove through very heavy rain for about 500 miles and then the temperature dropped from about 40F to 15F that night. The compressor main fuse blew when the compressor was unable to run (I could hear it trying to run) the next morning. I have never been able to reproduce that event even with large temperature swings.
Hmm, I only heard of hot weather option, for the AC. Nothing for compressor.
Strange that it was a software option, not hardware. Software can only change intervals of run, etc, not change the physical contact, etc of internal parts.
If anyone heard of this option, please chime in.
It seems that Porsche has gone thru at least 7 design iterations trying to make this system more reliable. Mine was replaced in January of this year so maybe the latest is beyond rev G? I sure drove in plenty cold weather conditions since the replacement and so far so good!
Traveling overseas currently so no access to my paperwork but if further details are needed I’ll post upon my return.
I checked my paperwork and the option I chose was to reprogram the PASM for a $90 fee which offers protection down to -13 degrees F. I don't see the details of the part revision but I remember my mechanic telling me it was the original compressor w/ P/N "A" and the new unit was version "G". Here's the info for those interested:

Relay (small black square in trunk) is what turns on compressor after ECU tells it to turn on.
New relays were made to change voltage.
Your car showed compressor overheating.
I do not see how changing program makes it good for lower temp. Other than making it work for shorter time. Shorter on time reduces heat, preserves compressor parts, not protecting to lower temp.
Hard to tell since no explanation.
