P1AFA on Mercedes-Benz
Quick Charger READY Time-Out
P1AFA on Mercedes-Benz vehicles indicates quick charger ready time-out. Au7o has documented this code across 1 Mercedes-Benz model — most commonly on GLE. P1AFA is a manufacturer-specific code used on the Mitsubishi i-MiEV electric vehicle (and its platform twins, the Citroën C-Zero and Peugeot iOn) for the DC quick-charging (CHAdeMO) system. It sets when the quick charger's present output voltage stays at or below 200 V for 10 seconds or longer, meaning the external DC fast charger failed to reach its READY state. The result is that the vehicle cannot complete a DC fast charge, though normal (AC) driving and onboard charging are typically unaffected. Typical repair costs on Mercedes-Benz range from $800 to $4,500, depending on the specific model and root cause.
Common Causes of P1AFA
- •Malfunction of the external DC quick charger (CHAdeMO station) itself
- •Faulty or dirty quick-charge connector or charge-port contacts on the vehicle
- •Damaged or high-resistance quick-charge cable / communication wiring between charger and vehicle
- •CHAdeMO communication (CAN) handshake fault between charger and the vehicle's EV-ECU/battery management system
- •Quick charger output voltage too low or charger not compatible with the vehicle's high-voltage battery
- •Fault in the vehicle's quick-charge contactor circuit or charge control module

Mercedes-Benz GLE(1 issue)
- 48V Mild-Hybrid ISG / 48V Battery Malfunction Causing Sudden Power Loss2020-2025
GLE models equipped with the EQ Boost 48-volt mild-hybrid system (GLE 350, GLE 450, GLE 450d, GLE 580 and AMG variants on the W167 platform) commonly trigger a '48V Battery Malfunction' or 'Hybrid System Error' warning. The integrated starter-generator (ISG) and 48V lithium-ion battery, along with the DC/DC converter, are known weak points. Owners report sudden loss of drive power on the motorway, disabled stop/start, weak acceleration and repeated stalling, sometimes resolving only after the car is powered down for 10-15 minutes. A March 2022 Mercedes TSB acknowledged that the battery self-test can disconnect the 48V battery due to software, hardware, cooling or false-positive faults. Many owners report multiple unsuccessful dealer visits and weeks of downtime, with the fault often persisting under warranty.
