Electronic Steering Replacement?

The wife took her 2012 ML350 in for service and this is what she received.

It's more than half the vehicle's value. I'm wondering, as I am an excellent shade tree mechanic, if this doable in the garage?

Was this at a Mercedes dealership or an independent?
I would go somewhere else for a second opinion.
What is the code number that was given that would cause that message to appear?
If you are in the rust belt, it may be worth replacing the chassis grounds as they may have corroded which could cause electrical issues.

Agree on second opinion. What symptoms are/were you/wife experiencing?

I'd be seeking a second opinion based solely on spelling.
Yes, really.

It's $8000 worth of motivation!!

Don't rush to replace rack without troubleshooting!

Don't under estimate poor GND or unstable CAN modules...

First step is to SCAN THE WHOLE CHASSIS to get fault descriptions.

The rack solderless junctions may well be toast but may also be remotely upset by network... scanner time.
