My vehicle is a 2011 Mercedes Benz ML350 Base (no 4Matic), with 76,500 miles.

Yesterday morning the vehicle was fine, now I have a check engine light and after using a diagnosis tool, I got back 5 Error Codes:

P0456 - Evaporative Emission System Leak Detected (Very Small Leak) 

0522-00 - Diagnosis of tumble flap ' Intake Manifold ' : Open circuit of sensor lines / Tumble flap

1089-00 - Purge Control System Has A Slight Leak (Minor Leak)

062F-00 - Internal Control Module EEPROM Malfunction

5126-00 - L6 / 3 (left rear speed sensor) Check installation position of sensor.

Could someone please help me understand what is going on and how I may fix it myself? Thank you for your help.


You may have a small leak on the fuel tank. Have you checked or replace the gas cap.

That is one issue that you have. The rest of the codes, I think are due to a SAM failure.
