That seems like a bad connection or faulty wire from where I sit.
It could be worst and one of the computer bit the dust or works only half or???

CAN (Controller Area Network) is a electronic bus (two wire) that communicates serially binary data between the various On Board Computer and other "smart " devices.

Strangely, I am guessing your car does run, with a CAN failure your car should not run, or at least miserable.
If it runs but badly, this is a good sign! Then the ECU might have fallen into "LIMB HOME" or simply runs of default without any adaptation.

Meaning, the ECU is probably fine. The next one could be the e-gas, passenger side under carpet, there is a metal plate that is held by a single phillips screw.
Underneath is the e-gas computer. Check that connector.
Since all devices, connected to CAN, have the abillity to keep the bus signal at a fixed state, any device that is on that bus is suspect, even the ABS computer!

Check your connector, passenger side behind the battery and make sure they are properly seated.
Other than that, only a STAR diagnostics scanner with live data might shed light into the dark.
If the CAN is canned, then the scanner can't hook up with computer either, since it would try to pull data from the CAN.

A MB shop might be able to swap ECU, E-gas and other "smart" controller to determine which one is holding the bus down.

Otherwise, anything is guess works.
