Hi

We got hit with some heavy rain a few weeks ago and when I was returning back home from work during a storm everything was fine until I took one bend and the left side of my car went into a deep'ish puddle, car slipped a bit felt through my steering wheel but nothing dramatic, and then a warning came on saying increased steering effort drive moderately.

Steering still feels fine, I have power steering, but I noticed I have to do more rotations to U-turn and it's less stable on bumps. So I think I have lost active steering. I also can't switch driving modes I only have Comfort mode, and the DSC light is permanently on.

I thought maybe it was some water in the steering box plugs and would dry off the next day but the error was still there. Took it to a garage and he took off all the plugs and dried them, no change. Tried recalibrating the active steering on ISTA, but it always fails at the end.

I thought maybe it's the sensor on the active steering servomotor, so I swapped out the active steering sensor + servomotor, tried ISTA again but still got the error.. I'm starting to think maybe it's the Active Steering Control Unit under the driver seat carpet.

Has anyone faced this problem before? With active steering and DSC going at the same time? Is there a way to test the active steering module or the cables/plugs going into the control unit with a multimeter? I want some way of being sure before buying a replacement since it's quite expensive..
