GLC 350e Hybrid plugin, 2017 fault code P1D8C9
with the cold engine I can drive the car normally in hybrid, electric, charging mode.
If I stop the car after 30km, the above functions will not work anymore, the car will run just on the fuel engine even if the battery is at 50% charged. Also the charging while driving is not working.
yesterday I went to a grind and read the fault codes,
P1D8C9 was the one that pup back after reset the faults.
Some suggestions will help.
Thank you
