I recently replaced front silent blocks on my volvo S40 2010 model. After replacement headlights performance was reduced. Actually the beam is very short. It is very difficult to drive high speeds during the night. The headlights are active bending xenon, so they do not have manual adjustment. I visited twice local volvo dealer but they did not manage to fix the problem. During start up headlights did not move evenly. After a couple of weeks an alarm for headlight malfunction came up. Still, the local volvo dealer could not do anything. Please advice.
