My W211 E220 CDI can't start with showing ESP display faulty and ABS display faulty. Please help me. Appreciate any suggestions. thank you.

 

Gotta get the codes to know what's happening...

 

 

Remove your central gateway module which is located under the dash on the driver's side. Unplug both connectors and check for corrosion.

 

I will try follow your suggestion this weekend and tell you then.Thank you very much.

 

i did this while troubleshooting a nonresponsive airmatic situation. found corrosion on the circuit board, then cleaned the corrosion. i have not tried SDS yet but im unable to read many control modules in the car using similar scan tools. only ME, TCU, SBC modules are communicating. thinking its the central gateway but the diagnosis tab on the star wiring says not many wires are able to be tested anyways
