Summary
Complaint After the charging process is complete, an instrument cluster message with a charging error appears and FC P0CFE00 is stored in control unit "N83 - AC charger for high-voltage battery (SG-LG)". The instrument cluster message and the FC memory entry can also appear at the beginning of the charging pause during delayed charging. Both only occur in combination with active pre-entry climate control. Cause Software in control unit "N83 - AC charger for high-voltage battery (SG-LG)". Remedy For model series 206 and 223 with code 802: Perform SCN coding in control unit "N83 - AC charger for high-voltage battery (SG-LG)". Please do not replace any parts even if the FC P0CFE00 coding continues to appear after successfully completing this step. A new software fix is currently in development and will likely be published in 01/2026. Replacing parts will not remedy the issue. For model series 243: The correction is already available. Perform a software update and SCN coding for the control units "N116/5 - Direct current charging connection unit (DCCU)" and "N83/11 - AC charger for high-voltage battery (SG-LG)" in order to remedy the problem.
