Your C4 has a traction control system that uses hydraulic cylinders (locks) to control the differntials in response to how the car is behaving. I've attached a drawing of the lock control circuit. I'd try beelding the locks first. You need a diagnostic unit that has the proper functionality to do it. I also suggest getting the "Prosche 911" enthusiast's Companion" by Streather.

Thanks for answer I was going to start buying the wheel speed sensors but then i start thinking if is the ecu whats damage, if is the selenoide valve whats bad, so i decide to take it to the mechanic
THANKS!
