Mercedes-Benz EQB Charger Won't Start: Quick Fixes
You have connected your Mercedes-Benz EQB to a public charger, but the session will not start. MBUX shows nothing, the charger sits idle, and you are wondering what is wrong. This is one of the most common complaints at public chargers, and it is usually fixable on the spot.
Symptoms
- The charger screen stays on 'waiting' or 'connect vehicle' after plugging in
- MBUX does not show any charging activity
- The EQB's charge port LED does not illuminate
- The charger returns an error code after you connect
- The CCS2 connector does not click into place
What to Do
- 1
Unlock the EQB and open the charge port
Ensure the car is unlocked. Press the charge port flap to open it. On some EQB models, you can also open it through the Mercedes me app.
- 2
Insert the connector firmly
Push the CCS2 or Type 2 connector straight into the port until it clicks. The charge port is on the right side of the EQB. A locked connector triggers the charging protocol.
- 3
Authenticate at the charger
Tap your RFID card on the charger reader, start the session in the network app, or tap your bank card on the contactless terminal. The charger needs authorization before sending power.
- 4
Disable scheduled charging in MBUX
In MBUX, navigate to EV settings, then charging. If a schedule is set, switch to immediate charging so the EQB does not wait for a timer.
- 5
Disconnect and retry
Unplug the cable, wait 15 seconds, and reconnect. This forces a fresh handshake between the EQB and the charger.
- 6
Try another charger
If the charger remains unresponsive, it is likely out of service. Move to a different stall or station and report the faulty unit through the network's app.
