VAG MLBevo MQB Chargers

There's a generational difference between the 1-2 phase PHEV chargers, and the newer MLBevo type used on the Audi E-Tron, E-Tron GT & Porsche Taycan

Difference between MLBevo/MQB vs. MEB Chargers

MEB has different AC connector and therefore also different chargeport. Possibly not compatible with all the information here. The E-Tron chargers have several things which make them a bit different, one major being the LIN LED module and Door actuator, as well as only having a Hybrid CAN connection (No Drive CAN).

MLBevo/MQB Chargers Overview

There are many different variants of MQB and MLBevo chargers with a wide range of potential power outputs.

These charges are not recommended if you are looking for a known working solution.

AC Connection

Golf GTE and all 5QE915682 series 3.6 kW chargers - Part number TE Connectivity 2103177-2

MLBevo

TE YHVA630-5phm-6mm-A and HV output coding A is 2141256-1

HV Connection

It doesnt care what you connect to the HV wires. 360v, 12v, heating element, dead short. Its mission in life is pumping current. It just dumps out voltage even when it does not see any voltage present.

Coding

MLBevo chargers seem to all use the EV_OBC3Phase1KLOMLBev16B config/odx. 20103 for the security code.

LIN Devices still show up within the DTC Memory, However no functional issues with them disconnected as long as the coding has them coded out. Similar errors exist for the door and other coded out options. Assumption is that the base software still has the DTC codes enabled for faults, however the selection is universal for the base charger option. (much like how most times you can code out a O2 sensor, but the DTC code will remain unless digging deeper into the ECU programming)

VCDS

You can open in the VCDS LCode.exe program (no purchase needed) and it's a interactive way to determine the coding value required. Coding label file available here. Shouldn't be necessary for newer versions of VCDS. Working with a Hex_V2 Cable.

• HVEM_02 - 0x5AC - Useable Energy for Comfort Functions

• HVEM_05 - 0x552 - Fun items relating to Max Voltage and Plug Release

Signals I'm sending In addition:

• Airbag_01 - 0x40 - Monitors HV Deactivate status

• BCM1_04 - 0x64F - BCM Charge Status indication - Likely just confirmation feedback

• DCDC_03 - 0x5CD - 400v to 800v converter - Likely not required

• EM1_HYB_11 - 0x37C - Signal for E-Motor Status - Can be 0 for standby

• FCU_02 - 0x17B - Contains Tank Flap Release & Signal which may go High to signal ready for charging (EPB, Drive System Disabled)

• NavData_02 - 0x485- This along with Authentic_Time_01 contain a 32-bit epoch unix time, used for the charge time calculation.

• VIN_01 - 0x6B4 - Mux'd VIN# - Likely not required or just mimic the Donor Vin?

• ZV_01 - 0x184 - Signal to unlock via ZT - Maybe will unlock charge plug

• ZV_02 - 0x583 - Lock status, likely not required

Signals I haven't added:

• Dimmung_01 - 0x5F0

• Einheiten_01 - 0x643

• ESP_49 - 0x96A954AE - Contains Value for Regen reserve, Guessing that ESP will average typical SOC% to reserve to allow regen - Likely not required

• NVEM_02 - 0x663 - Contains Battery Voltage from Battery Data Module

• MSG_HYB_30 - 0x153 - Only seems to use the Counter & Checksum?
