Luism Posted August 30, 2018 Report Share Posted August 30, 2018 Hi all I have 2006 cayenne S and every now and then since like a month ago I get the flash up on dash with ( Four wheel drive system faulty) then goes off for a few days and comes back on. The shifter does work and the trans can be put in low and high range and goes perfectly well but its a nuisance getting the light pop up every now and then. Anyone know why this happens please? thanks all Link to comment Share on other sites More sharing options...
Gaurav Posted August 30, 2018 Report Share Posted August 30, 2018 Get your battery checked and changed (if needed), I had this same issue but only once and next day battery died. So this four wheel drive faulty is a known issue when battery dying as it has electronic oil and when that oil gets a fluctuation in voltage it throws this error. Let's root for each other & watch each other grow. Link to comment Share on other sites More sharing options...
