Default Loss of AWD?

Driving to work this AM out of nowhere Dash lights up "Loss of 4 wheel drive safe to drive". Anybody have any ideas of anything I can check before I bring it to my dealer? Car is 2014 and has 12,345 on the clock and I do not track.

WOW never heard of that one.

Let's hope it's just a sensor and not the diff.

Please update when figured out.

Funny just got off the phone with my service Rep. and his reply was exactly the same, " WOW never heard of that". It was NOT what I wanted to here and neither did it inspire confidence.

OK C4s owners they are still looking at the car but they thing it my be the transfer case! First one they have seen on a 991. They tell me that Porsche is apparently having Macan and Cayenne transfer cases grenade themselves but this is the first 991 that MAY have the problem that they have seen. Still checking the car out and they still may find something as simple as a fuse. Hoping for the best prepping for whatever comes.

If it has to be replaced I recommend stepping up to a 4:1 RockTrac out of a Rubicon. An atlas 4 speed is going to be overkill on a Carrera.

Thank you for keeping us informed on this issue. Can you comment on if the warning was locked in still even after a restart of the engine etc. Sometimes these electrical gremlins reset after a reboot.


I've had several warnings that went away upon restart on my 981.

I'm curious why?

I am just debating to get a 911 and pondering

S v GTS
RWD v AWD
MT v PDK

there's a lot of room to think.

I do live in a snowy area, but likely will keep my Subaru as a second car, so 911 likely won't see the snow.

however rain etc.. will still be something, but I did live ok with M3 as my only car at one time with snow tires.
