Hi All
recently cracking sounds like TUC TUC are coming when i turn the car at slow speeds, specially when i am reversing. seems like the sound is coming from back window or back wind screen or maybe sun screen at the back. any idea what it may be and how i can fix this ? 2014 e350.
Thank you !

 

Commonly, I've seen the sunroof frame making that noise. The fix is dropping the headliner and tightening them. You'll normally find one that's really loose. I use loctite so that I don't have to do it again.

Hope this helps B

 

Thank you will try.
