Hello Community I own about 9 months a Renault Grand Scenic 3 bj 09/2014 With a 1.5 dci engine 110 hp. alternator would be renewed already. Because the freewheel broke. Be in the standing of the car. Some think of the hydromotor bearing be it. As I said only in the stood irregularly. Then I have 3 months always unbalanced sounds during the ride, always to hear well at 80 km/h. I drove it out the other day, then ran on parking and engine. And exactly there I e i can hear these sounds in the stand, where otherwise only during the ride were to be heard. Then unfortunately also comes the xenon headlights become darker when I switch into the next gear or only become brighter when the gear is in it like with the moped earlier. I was already in 2 Renault workshops, without result. It is a great family car that I would like to drive even longer. Who has an idea or experience with these causes??
