The B9 S5 coupe is a legitimate platform for a suspension upgrade, and the Quattro AWD drivetrain makes it work in almost any condition. What complicates the coilover installation is the factory EDC setup. The moment those OEM adaptive dampers come out, the Electronic Damping Control module starts throwing faults and your dash reflects it with warning lights that do not go away on their own.
The KW EDC Cancellation Kit solves it cleanly. Connect it to the existing EDC wiring harness and the factory module receives a simulated signal that reads as a normal, healthy damper connection. Warning lights clear, the fault log stays clean, and the S5's Quattro system, stability control, and other electronics continue operating without interruption.
