i have a cayenne 2011 writing ALL WHEEL SYSTEM IS OVERLOADED !!! and this is the second time. First time i changed the sensor of the ABS, and now I'm facing the same problem. Can someone HELP plz????

This fault can be displayed when the battery is bad, so get it checked. BUT, if it only comes up when you start the car, it could be the 4 wheel drive motor. If the battery checks out ok, try this simple test before visiting repair shop: 1. Stop and start your engine (in case you got already fault message) 2. Activate off-road /Low Range mode/ driving program (use rocker switch) with gear shift lever in neutral position 3. Drive your car for a while (move forward/backward several meters) 4. Activate on-road /High Range mode/ driving program (use rocker switch) with gear shift lever in neutral position It may "heal" your all-wheel drive system, e.g. resistor, which identifes mode in which system is and generates fault message when corroded - it happens when you do not use this feature for a long time...
