"Help Needed"2014 E63S Wagon,rear vibration and knocking sound at full turn
Hi, guys:
My 2014 wagon is 3-month old now with 3K km on it already. Did my first LSD oil change last week, everything is fine apart from two issues.
1.When I accelerate at low speed, sometimes I can feel vibration from rear, possible rear axle. after a few seconds, it is gone.
2. When I make a almost-full left turn, I hear a one time knock sound from the front wheel. like I drove over a rock or something. it mostly happens in reverse gear while turning.
Plus I start to hear noise from front brake pad while breaking at low speed to static, not sure if it is because of cold weather.
Anyone has similar issues or experience, please share. Thanks.
Pic added, thread is less boring with pic

The rear vibration is usually the stupid mct trans wet clutch engaging and often worse in Eco mode, worse when warmed up too... Normal operation, also felt on the 2014 s63, cls64...
The tires clunking is the cold affecting the soft rubber of the summer tires ... You need winter tires to make it go away... Also normal
