Hello, I'm new to the forum and looking for some assistance.

I have a 2011 ML350 Bluetec. Driver side blind spot indicator light on the mirror starts flashing intermittently while the vehicle is on and not moving.
Once past 20km/h or so, it turns off as normal and will turn red if another vehicle is at either left or right side, essentially operating as normal.
When I stop, sometimes on, sometimes it's not, sometimes flashing... passenger side is completely fine.

Any advice would be greatly appreciated.

 

What is the message in the Inst. Cluster, word for word?

That's the interesting part, no message on the instrument cluster at all. Just the little triangle on the drivers flashing from time to time.
To me, it seems like a loose connection or corroded connection.

 

Well then you have to investigate.
