VW e-Golf

Vehicle Type: VWEG

This vehicle type supports the VW e-Golf. Connection is made via the J533 gateway module, preferably using a harness adapter that plugs into the existing connector.

Adapter

The adapter connects to the J533 gateway harness connector, giving access to the Comfort CAN (KCAN) and Powertrain CAN (FCAN) buses. KCAN carries the majority of metric data. FCAN carries the VIN and a small number of powertrain frames; the J533 also bridges KCAN traffic onto FCAN, so both buses are registered by the module.

The adapter extends the car harness — pins are connected straight through, with the CAN pairs run as twisted pair (e.g. from CAT6 cable). The connector part number is VW 8E0972420 (buy both male and female).

Installation

Installation does not require removal of any trim pieces. The J533 gateway module is located under the steering wheel, above the pedals. Position yourself face-up under the dashboard — you should see the gateway module with its red connector from there.

Unplug the red connector, plug in the adapter, connect the OVMS module to the adapter, and tuck it somewhere in the dashboard.

Basic Configuration

After selecting the VW e-Golf vehicle module, data should start flowing in once the car is awake.

Others

Cabin Climate Control

  • Temperature setpoint is set in the car’s infotainment system (e-Manager)

  • Climatise on battery power is force-enabled

  • OVMS may show the car as charging/plugged-in even if it is not charging/plugged-in

Charge Control

Charge control only applies to the default settings in the car, not the user defined charge locations/departure timers.

This means:

  • Current limit does not apply by default if you have departure timers enabled because the car will not use the default settings.

  • The moment you use the charge control feature the car will switch to the default charge profile, charging it to 100% SoC

  • You cannot switch back to your departure timer via OVMS, press the delayed charging button on the charge port

Furthermore to make it compatible with climate control:

  • When climate control is started while charging you have to turn off climate control first before you can stop charging

  • Enabling climate control while plugged in will cause the car to start charging again

  • To avoid climate preconditioning from starting when using the charge start command while unplugged the flag “climatise on battery” is cleared

Charge current limit only supports a few set values: 5A, 10A, 13A or 32A (= Max)
