Audi e-tron GT Charging at Mer

Audi e-tron GT Charger Won't Start Charging

You have plugged in your e-tron GT, but nothing happens. The MMI screen stays silent or shows an error. The e-tron GT has two charge ports, one on the left rear for AC and one on the right rear for DC, which can add confusion. This is frustrating, but it is almost always fixable on the spot.

Symptoms

• CCS2 or Type 2 connector plugged in but no charging indicator on the MMI touchscreen
• Charger screen shows 'Waiting for vehicle' or stays on the start screen
• e-tron GT charge port LED blinks but charging never begins
• Authentication succeeds on the charger but the session fails to start
• Plugged into the wrong charge port for the type of charging

What to Do

1. 1

   Verify you are using the correct charge port

   For DC fast charging, use the charge port on the right rear of the car. For AC charging with a Type 2 cable, use the charge port on the left rear. Using the wrong port is the most common cause of a failed start on the e-tron GT.

2. 2

   Check for a charging schedule or departure timer

   On the MMI touchscreen, go to the e-tron charging settings. If a timer or departure schedule is active, switch it to charge immediately or turn off the timer. You can also check the myAudi app for active schedules.

3. 3

   Unplug and reconnect firmly

   Remove the connector, wait 10 seconds, then reinsert it firmly into the correct charge port until you hear a clear click. Watch the charge port LED for a steady response.

4. 4

   Restart the charger session

   On the charger, end the current session if one is active. Then start a new session by tapping your RFID card, using contactless payment, or restarting in the charger operator's app.

5. 5

   Reboot the MMI system

   Press and hold the power button on the MMI touchscreen for about 10 seconds until the screen goes dark and restarts. Once it is back, try plugging in again. This resets the charging communication on the car's side.

6. 6

   Try a different charger

   If the station has multiple stalls, move to a different one. Some chargers have firmware issues that cause 800V handshake failures. A different unit at the same station may work fine.

Audi e-tron GT Charging Payment Failed at Station

You are at the charger, your e-tron GT is plugged in, but the payment will not go through. The charger shows an error or just sits there waiting. Payment failures at public chargers are common and usually have nothing to do with your car. Here is how to get charging.

Symptoms

• Charger displays 'Payment failed' or 'Authorization error' after tapping your card
• RFID card is not recognized by the charger's reader
• myAudi or Audi charging app shows an error when trying to start a remote session
• Plug & Charge does not activate after plugging in the CCS2 connector on the right rear
• Contactless payment terminal on the charger rejects your bank card

What to Do

1. 1

   Try a different payment method

   If your RFID card failed, try contactless with your bank card or phone. If contactless failed, try the charger operator's app. Having two or three payment options gives you the best chance of getting going.

2. 2

   Check the myAudi app

   Open the myAudi app on your phone. Make sure your Audi charging account is active, your payment method is valid, and Plug & Charge is enabled if you want to use it. Try starting the session remotely through the app.

3. 3

   Scan the charger's QR code

   Most public chargers have a QR code on the unit. Scanning it with your phone's camera opens the operator's payment page. You can usually pay with a credit card through the browser without downloading an app.

4. 4

   Check your bank app for blocked transactions

   Open your banking app and check for any flagged or blocked transactions. Some banks require you to approve the charge manually. If you see a notification, approve it and try the payment again.

5. 5

   Try Plug & Charge if available

   If the charger supports Plug & Charge and your e-tron GT has it activated through the myAudi app, simply unplug and replug the CCS2 connector into the right rear charge port. The payment should authorize automatically through the cable.

6. 6

   Move to a different charger

   If nothing works at this station, the charger's payment system may be down entirely. Find a nearby alternative using the myAudi app or the e-tron GT's built-in charger finder on the MMI touchscreen.

Audi e-tron GT Charging Slower Than Expected

You plugged in your e-tron GT expecting 270 kW and the MMI touchscreen shows 50 kW. With an 800V architecture designed for ultra-fast charging, this is especially frustrating. Slow charging on the e-tron GT is almost never a defect. It is usually the charger's capability, the battery temperature, or a mismatch between the station's voltage and the car's 800V system.

Symptoms

• DC fast charging speed well below the 270 kW maximum shown on the MMI touchscreen
• AC home charging stuck at 3-4 kW instead of the full 11 kW or optional 22 kW
• Charging speed drops significantly after reaching 50-60% state of charge
• The e-tron GT charges at similar speeds to 400V vehicles despite having 800V architecture
• MMI display shows lower power than the charger's rated output

What to Do

1. 1

   Verify the charger supports 800V and high power

   Check the charger's label or the operator's app for the maximum power output and voltage. For the e-tron GT to reach its peak 270 kW, you need a charger rated for at least 270 kW at 800V. A 150 kW or 400V charger will work but at much lower speeds.

2. 2

   Check the battery temperature

   Look at the charging screen on the MMI touchscreen. If the battery is cold, use the navigation system to route to the fast charger. The e-tron GT will precondition the battery on the way using its heat pump. If you are already at the charger, driving for 15-20 minutes and returning can help.

3. 3

   Check your state of charge

   Look at the digital instrument cluster or MMI screen. If you are above 80%, the slower speed is expected. For the fastest charging, arrive at the charger between 5-20% and charge to 80%.

4. 4

   Verify the charger is not sharing power

   Look at the charger unit. If there are two cables and someone is using the other one, you may be sharing power. Move to an unoccupied charger if one is available.

5. 5

   Check the AC charge current setting

   On the MMI touchscreen, go to the e-tron charging settings. Make sure the AC charge current is set to maximum. If you have the optional 22 kW onboard charger, verify your wallbox supports it.

6. 6

   Try a different charger

   If the speed is still low, the charger itself may be degraded or faulty. Look for Ionity, Electrify America, or other 350 kW networks that support 800V to get the best speeds from your e-tron GT.

Station occupancy not updating in the app

The Mer app shows a station as available, but when you arrive, all connectors are occupied or out of service. The real-time status in the app can lag behind by several minutes.

Symptoms

• App shows "Available" but all connectors are in use when you arrive
• App shows a station as occupied but the chargers are visibly free
• Connector status flickers between available and occupied in the app
• Recently freed connectors still show as "In use" in the app for several minutes

How to Fix It

1. 1

   Pull to refresh the station detail in the Mer app

   On the station page, pull down to force a status refresh. The app does not always update automatically, and a manual refresh often shows the correct status.

2. 2

   Close and reopen the app

   Force-close the Mer app and reopen it. This clears any cached station data and pulls a fresh status from the server.

3. 3

   Check a third-party app for a second opinion

   Apps like Plugsurfing, A Better Route Planner, or Google Maps sometimes pull fresher data from Mer's backend. Use one of these to verify availability if the Mer app seems wrong.

4. 4

   Drive to the station if it is nearby

   If the station is less than five minutes away, it is often faster to just go and check. Occupancy can change in the time it takes to troubleshoot the app.

Third-party RFID card rejected

You are trying to authenticate with an RFID card from a roaming provider like Plugsurfing, NewMotion, or Virta, but the Mer charger rejects it. Not all third-party RFID cards are accepted at every Mer station.

Symptoms

• Charger screen shows "Card not recognized" after tapping
• The charger beeps once but nothing happens
• Your RFID card works at other networks but fails at Mer
• The charger prompts you to try again but repeated taps do not help

How to Fix It

1. 1

   Hold the card flat against the reader for three full seconds

   Do not tap and remove quickly. Some Mer readers need a longer hold to register the card. Keep it pressed flat against the RFID symbol.

2. 2

   Check if your roaming provider covers Mer stations

   Open your roaming provider's app and search for this specific Mer station. Some providers have roaming agreements with Mer but not for every station type or region.

3. 3

   Use the Mer app instead

   Download the Mer app if you do not have it. Create an account and add a payment method. You can start the session through the app even if your RFID card does not work.

4. 4

   Try contactless bank card payment

   Newer Mer stations have a contactless payment terminal. Look for a card reader with the contactless payment symbol. Tap your bank card or phone to start.

5. 5

   Try a Mer-issued RFID card for future visits

   You can order an RFID card directly from Mer through their app or website. Mer's own cards are accepted at all Mer stations without roaming issues.

Charger screen showing error but no error code

The charger screen displays a generic error message like "Error" or "Fault" without any specific code or explanation. This makes it hard to know if the problem is temporary or if the unit is broken.

Symptoms

• Charger screen shows "Error" or a red warning icon with no further detail
• The error appears before you even try to authenticate
• The error appears after plugging in but before power delivery starts
• Screen alternates between the normal start screen and the error message

How to Fix It

1. 1

   Unplug the connector and wait 30 seconds

   Some Mer chargers show transient errors after a previous session ended abnormally. Unplugging and waiting gives the charger time to reset its internal state.

2. 2

   Try the other connector on the same unit

   If the station has a second CCS2 connector, try that one. A hardware fault on one connector does not always affect the other.

3. 3

   Check if other cars are successfully charging at the station

   If nobody at the station is charging, the entire station may be down. If others are charging fine, the issue is limited to your connector.

4. 4

   Report the faulty unit in the Mer app

   Open the Mer app, find the station, and report the issue. Include which connector number has the error. This helps Mer send a technician and warns other drivers.

5. 5

   Move to a different station

   A charger with a persistent generic error is unlikely to start working on its own. Use the Mer app to find the nearest alternative station.

Cable locked and will not release in cold weather

You finished charging but the CCS2 cable will not unlock from your car. In Nordic winters, ice can form around the connector locking mechanism, making it physically difficult to release.

Symptoms

• Pressing the connector release button does not unlock the cable
• The connector feels frozen in place
• Your car shows "Charging complete" but the cable is stuck
• The locking pin on the connector is visibly iced over

How to Fix It

1. 1

   Make sure the charging session has fully ended

   The cable stays locked while a session is active. Stop the session in the Mer app or on the charger screen, then try releasing the connector again. Wait 10 seconds after the session ends.

2. 2

   Try unlocking from your car

   Most EVs have a cable release option in the infotainment system or a button near the charge port. Use your car's unlock function rather than the connector button.

3. 3

   Warm the connector gently

   If ice is the problem, pour lukewarm water (not boiling) over the connector and charge port area. You can also cup your hands around the connector to warm it with body heat. Do not use force or tools to pry it free.

4. 4

   Run the car's cabin heater for a few minutes

   Turning on the car's climate system can gradually warm the charge port area from the inside. This works slowly but can free a mildly frozen connector after 5-10 minutes.

5. 5

   Call Mer support if the cable is truly stuck

   If nothing works after 15 minutes, call the support number on the charger. Mer can remotely release the cable lock on their end. Do not pull with excessive force as this can damage both the connector and your car's charge port.

App requires location services for remote start

The Mer app asks you to enable location services before you can start a charging session, even when you are standing right next to the charger and selected it manually from the map.

Symptoms

• App shows "Enable location services to start charging" popup
• Start button is grayed out until location permission is granted
• The app worked fine before but now demands location after an update
• You can browse the map but cannot start a session without GPS enabled

How to Fix It

1. 1

   Enable location services temporarily

   Go to your phone's settings, find the Mer app, and set location access to "While Using the App." You can change it back after your session.

2. 2

   Make sure GPS has a fix

   In underground parking garages or areas with poor GPS reception, the app may not be able to confirm your location. Step outside or move closer to an open area until the app detects your position.

3. 3

   Use RFID or contactless payment instead

   If you do not want to share your location, use your RFID card or a contactless bank card to start the session. These methods do not require the app at all.

4. 4

   Scan the QR code on the charger

   Some Mer chargers have a QR code that opens the start process in a browser, bypassing the app's location requirement.

Former Grønn Kontakt station not found in Mer app

Mer acquired Grønn Kontakt in Norway, but some older stations may not appear correctly in the Mer app, especially during the transition period.

Symptoms

• Station visible on the street but not on the Mer app map
• Searching by the old Grønn Kontakt name returns no results
• QR code on the charger links to a Grønn Kontakt page that no longer works
• RFID card from Grønn Kontakt account rejected

How to Fix It

1. 1

   Update the Mer app to the latest version

   Older versions of the app may not include recently migrated Grønn Kontakt stations. Update from the App Store or Google Play.

2. 2

   Search by the station's physical address

   Instead of searching by station name, try the street address or zoom into the location on the app map. The station may appear under a new Mer name.

3. 3

   Enter the charger ID manually

   Look for a station or connector ID printed on the charger hardware. Enter this ID in the Mer app's manual start option.

4. 4

   Use contactless payment to bypass the app

   If the station has a payment terminal, tap your bank card to start. This works independently of whether the app has the station listed.
