C5 lateral rocking: actuator test doesn't show sensors' information.

Post by sbregov »

Hi, I suffer from excessive lateral rocking and look for any information.

The ride itself is soft enough, Diagbox doesn't show any mistakes, Hydractive height corrector works well, switching sport mode makes it distinctive in the ride. Stock corner spheres are all right as their pressure has decreased only by 10-15% for years. ESP and headlights cornering operate properly. Suspension bushings are ok.

I've tried to perform the actuator test to confirm that the electrovalve has been energised, but in the field "Cause: changing between firm / soft" there is only "Compression movement" and "Acceleration". I suppose to see something like "steering wheel speed change" or "lateral acceleration" but nothing else is shown.

May it point to any certain failure? Is there any other tests to show whether roll relates to BHI or actuator?

Is there anybody who ever conducted actuator test in drive? Some tech guy told me that it is correct behavior of test.
