DSA lamp on the dashboard (the orange triangle with a car on slippery road) lights constantly! Pressing DSA button (on|off) does nothing! I can't turn the system on. The description of the DSA system in the user manual is not detailed enough.
The official dealer service station stated "DSA system failure" but didn't offer any solution.
As far as I know the cause could be either in ABS sensor failure or ABS control unit failure or DSA unit failure. Is there any way to determine the cause without buying new units? Or could it be anything else?
