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

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.

Coding

MLBevo chargers seem to all use the EV_OBC3Phase1KLOMLBev16B config/odx

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.

• 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
