I own the car for more than a year and it has always been like this, but it's now starting to work on my nerves and I wonder if I can do anything to prevent it.
During this time I have changed most of the suspension: Koni sport shocks and all kinds of bushings. Everything that my mechanics advised for. Currently they say that "there is nothing that needs changing". I'm thinking about changing the springs with more stiff ones as well (currently I have the original ones I guess), but I have no idea if this is going to better the situation.
The car is stable while cornering... at least with the speeds I dare to corner
But the problem is when going over bumps. And especially over steeper speed-bumps.
I am not sure I can describe it very well but I'll try:
Variant A:
1. one front wheel hits the bump and my steering wheel does (or tries to do) several jerky motions.
2. the other wheel hits the bump and again, the same happens.
Variant B:
Both wheels hit the bump at (almost) the same time. It feels like both wheels get displaced backwards. The steering wheel becomes "softer" then "stiffer" several times before the car finally gets stabilized on top of the speed bump
I have servotronic fitted from another car but this problem was present before we installed it.
I have talked to other people driving C4 cars and they say that "these cars drive like that".
Still, I decided to ask you, as it really annoys me and it would be great if I can do something to fix it.
