Why Your Charging Speed May Differ

The Audi e-tron GT supports up to 270 kW DC charging. REWE Charging chargers deliver up to 300 kW. Your car's maximum intake is the limiting factor here, capping speed at 270 kW even on a faster charger.

  • Charging slows down above 80% state of charge on most EVs, including the Audi e-tron GT.
  • Cold weather reduces charging speed. The Audi e-tron GT supports battery preconditioning, which helps.
  • If multiple cars share the same REWE Charging station, power may be split between stalls.

Audi e-tron GT Charging Problems

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.

Common REWE Charging Issues

Charger occupied by non-charging vehicles

You arrive at the REWE charger and a car is parked in the charging spot without being plugged in. This is common at supermarket locations where shoppers treat EV spots as regular parking.

Symptoms

  • Charging spot is occupied by a car with no cable connected
  • ICE vehicle parked in the EV charging bay
  • Car is plugged in but session has clearly ended and the driver is inside shopping
  • All charging spots taken despite the app showing the charger as available

How to Fix It

  1. 1

    Check if the other car is actively charging

    Look at the charger display or connector. If the session has ended and the car is just parked, REWE cannot remotely move it. The app status reflects the charger, not the parking spot.

  2. 2

    Ask at the REWE customer service desk

    REWE staff can sometimes make a store announcement asking the vehicle owner to move. This works more often than you would expect.

  3. 3

    Wait briefly or shop first

    At supermarket chargers, turnover is high. Most shoppers leave within 30 to 45 minutes. Do your shopping and check again.

  4. 4

    Check for additional REWE locations nearby

    Many German cities have multiple REWE stores with chargers within a short drive. Check the app for the next closest option.

Contactless card reader not responding

You tap your debit or credit card on the reader but nothing happens. The reader does not beep, does not show a light, or shows an error briefly before resetting.

Symptoms

  • Card reader shows no response when you tap
  • Reader beeps but the screen shows an error
  • Card works at the REWE checkout inside but not at the charger
  • Contactless symbol is visible on the reader but it seems inactive

How to Fix It

  1. 1

    Hold your card flat against the reader for 3 to 5 seconds

    Some REWE charger readers are slower than store payment terminals. Hold the card still and wait for the full processing time.

  2. 2

    Remove your phone and other cards from the area

    If you hold your wallet with multiple contactless cards near the reader, it may detect interference and reject the transaction.

  3. 3

    Try the charging app instead

    If contactless is not working, start the session through the REWE charging partner app. This bypasses the physical card reader entirely.

  4. 4

    Check if the reader is physically damaged

    Supermarket chargers are exposed to shopping carts, weather, and heavy foot traffic. If the reader looks cracked or the screen is damaged, report it to REWE staff inside and try another stall if available.

Session ends due to maximum stay time limit

Your charging session stops before the battery is full because REWE enforces a maximum parking time at the charging spot. This exists to keep spots available for other shoppers.

Symptoms

  • Charging stops after 60 to 90 minutes even though the battery is not full
  • App notification says session ended due to time limit
  • You return from shopping to find the charger disconnected
  • Charger screen shows session completed despite low battery level

How to Fix It

  1. 1

    Check the posted time limit before you start

    REWE typically allows 60 to 120 minutes depending on the location. Look for signage near the charger or check the app for time restrictions at that specific store.

  2. 2

    Plan your charge around your shopping time

    At up to 300 kW, most EVs can gain 150 to 250 km of range in 30 to 45 minutes. A normal grocery run is usually enough time for a meaningful charge.

  3. 3

    Move your car if you need more time

    If you need a longer session, move your car to a regular parking spot after the time limit and start a new session if the charger is free when you return.

  4. 4

    Use REWE chargers for top-ups, not full charges

    Supermarket chargers work best for adding range while you shop, not for charging from 10% to 100%. If you need a full charge, plan for a dedicated fast charging station.

Poor mobile signal in underground or garage parking

Some REWE stores have chargers in basement or covered parking areas where mobile signal is weak. This can prevent the app from starting a session or processing contactless payments.

Symptoms

  • App shows 'No connection' or spins without loading
  • Contactless payment times out during processing
  • You cannot scan the QR code on the charger because the page will not load
  • Session starts but the app loses connection and cannot show charging status

How to Fix It

  1. 1

    Connect to REWE store WiFi if available

    Many REWE stores offer free WiFi that may reach the parking area. Check for a REWE network in your phone's WiFi settings.

  2. 2

    Walk closer to the garage entrance to start the session

    If you need the app to start the session, walk toward the exit where signal is stronger, start the session remotely, then return to your car.

  3. 3

    Use contactless payment instead of the app

    Contactless card payments are processed through the charger's built-in connection, not your phone. If the card reader works, you do not need mobile signal.

  4. 4

    Pre-load the app before entering the garage

    Open the app and navigate to the station page while you still have signal. Some apps cache enough data to start a session even with intermittent connectivity.

Charger unavailable outside store hours

You arrive at a REWE charger outside store opening hours and the charger is inaccessible or powered down. Some locations gate their parking areas or shut down chargers when the store closes.

Symptoms

  • Parking area gate is locked and you cannot reach the charger
  • Charger screen is dark and does not respond
  • App shows the charger as available but the physical location is closed
  • Barrier arm blocks entry to the parking lot after closing time

How to Fix It

  1. 1

    Check store hours before planning a charge

    REWE stores in Germany typically close between 20:00 and 22:00 on weekdays and earlier on Saturdays. Most are closed on Sundays. If the charger is behind a gate, you cannot access it outside these hours.

  2. 2

    Verify 24/7 access in the app

    Some REWE charging locations offer 24/7 access even when the store is closed. Check the station details in the app. If it does not mention 24-hour access, assume it follows store hours.

  3. 3

    Leave the parking area before the store closes

    If you are charging and the store is about to close, make sure you can exit the parking area. Some locations lock the barrier after closing, which could trap your car overnight.

  4. 4

    Find an alternative nearby charger

    Use a multi-network app like Chargemap or the EVcourse charger finder to locate a 24/7 charger nearby. Dedicated charging stations along main roads usually operate around the clock.

REWE Charging App Tips

  • REWE chargers are often operated by a charging partner (such as Allego or EWE Go). Check which app you actually need by scanning the QR code on the charger or looking at the operator logo.
  • Pre-load the station page in the app before entering a parking garage. Underground signal issues are common at REWE locations.
  • Enable session end notifications so you can move your car promptly and avoid blocking the spot for other shoppers.
  • Check the app for time limits at each specific REWE location. They vary by store and are not always posted clearly on signage.
  • If the app is not working, look for a phone number on the charger itself. The charging operator (not REWE) handles technical support.

Payment Tips

  • Contactless debit and credit cards usually work at REWE chargers without needing an app or account. Look for the contactless symbol on the card reader.
  • Pre-authorization holds can be up to 100 EUR depending on the operator. The actual charge amount replaces the hold within a few business days.
  • Some REWE charging operators offer roaming through networks like Hubject or Gireve. Your existing charging card or app from another network may work here.
  • Keep your payment card handy, not buried in your shopping bags. If the session stops unexpectedly, you may need to re-authenticate quickly.
