Take the car back to the dealer, since this problem seems connected to the cluster replacement. I would also call the warranty company and COMPLAIN!!! A non-Mercedes cluster is not professional.

There is programming that must be performed on the replacment cluster. It is possible the dealer missed something. What does the dealer say?
They do not act like the two are connected. They are now checking the SAM unit. The problem started right after I reset some of the info such as lights on constant. I think the two problems are related
this is what i found on this website MB recall page.

Instrument Cluster Illumination May Fail

RepairPal Expert Overview

Our Quick Take:

The instrument cluster is the component that contains your vehicle's gauges, speedometer, and warning indicators. Mercedes-Benz has found that some instrument clusters have faulty lighting, which makes the gauges and speedometer difficult to read.

What Should You Do?

Please contact your Mercedes-Benz dealer. They will check to see if your specific vehicle is affected and advise you on what to do next. Always have your vehicle identification number (VIN) handy when you call.
