I have a problem with steering angle sensor on my Signum 2004. ESP light is always on. I have tried calibrating SAS modul but calibration failed. When I check the data from steering angle sensor when turning wheels angle changes but data changes in strange way (skips and shows values that are not realistic).

I have an idea to clean SAS. Has anyone tried to do that?

Replacing CIM modul is too much complicated and expensive.
