Why Your Charging Speed May Differ

The MG MG4 supports up to 142 kW DC charging. Le Plein chargers deliver up to 200 kW. Your car's maximum intake is the limiting factor here, capping speed at 142 kW even on a faster charger.

  • Charging slows down above 80% state of charge on most EVs, including the MG MG4.
  • Cold weather reduces charging speed. The MG MG4 supports battery preconditioning, which helps.
  • If multiple cars share the same Le Plein station, power may be split between stalls.

MG MG4 Charging Problems

MG MG4 Charger Won't Start? How to Fix It Now

You have plugged in your MG MG4 but nothing is happening. The charger light is blinking, the car is not responding, or you are getting an error message. This is frustrating, but most failed charging sessions have a simple fix. Let's walk through the common causes.

Symptoms

  • Charger display shows an error code or red indicator
  • CCS2 connector clicks in but charging does not begin
  • Car dashboard shows no charging activity after plugging in
  • Charger screen asks for authentication but does not accept your card or app
  • Charging port light on the MG4 flashes or stays amber

What to Do

  1. 1

    Check the charger screen for error messages

    Read any error codes or messages on the charger display. Common messages include 'authentication required,' 'connector error,' or 'out of service.' This tells you whether the problem is the charger or the car.

  2. 2

    Unplug and replug the connector

    Remove the CCS2 or Type 2 connector completely, wait 10 seconds, and plug it back in firmly. Make sure you hear the click and the MG4's charge port light responds.

  3. 3

    Authenticate again

    Re-tap your RFID card, restart the session in the app, or try contactless payment. Some chargers require you to authenticate before plugging in, others after. Try both sequences.

  4. 4

    Disable scheduled charging

    On the MG4's infotainment screen, go to vehicle settings and check if scheduled charging is enabled. Turn it off temporarily to allow immediate charging.

  5. 5

    Lock and unlock the car

    Use the MG4's key fob or the MG iSMART app to lock and then unlock the car. This can reset the charge port communication and clear temporary errors.

  6. 6

    Try a different charger or stall

    If nothing works on this stall, try another one at the same station. If the entire station fails, the problem is likely the charger infrastructure, not your MG4.

MG MG4 Charging Payment Failed? Fix It Quickly

You are at a charger with your MG MG4 and the payment is not going through. Your card gets rejected, the app throws an error, or you cannot figure out how to pay at all. Payment issues are one of the most common reasons a charging session fails to start. Here is how to sort it out.

Symptoms

  • RFID card tap does not register on the charger
  • Charging app shows a payment error or insufficient funds
  • Contactless bank card is declined at the charger terminal
  • Charger asks for payment but you cannot find a method that works
  • Session starts but stops immediately due to payment authorization failure

What to Do

  1. 1

    Check which payment methods the charger accepts

    Look at the charger for logos showing accepted payment types: RFID, app, contactless card, QR code. Many chargers display the logos of compatible networks near the screen or card reader.

  2. 2

    Try the network's app

    Scan the QR code on the charger or search for the network's app in your phone's app store. Many networks let you start a session through their app even without an RFID card.

  3. 3

    Try a different payment method

    If your RFID card fails, try the app. If the app fails, try contactless. If you have a multi-network roaming card (like Plugsurfing or Shell Recharge), try that instead.

  4. 4

    Check your card balance and bank notifications

    Open your banking app to check for declined transactions or pre-authorization holds. Contact your bank if the charger is trying to authorize a large hold that exceeds your available balance.

  5. 5

    Use a roaming service

    If you do not have an account with this specific network, a roaming provider like Plugsurfing, Chargemap, or Shell Recharge may cover this charger. These services work across multiple networks with one card or app.

  6. 6

    Find an alternative charger nearby

    If payment truly will not work, search for another charger nearby. Filter your charging app by your available payment methods to find a compatible station.

MG MG4 Charging Slowly? Causes and Quick Fixes

You plugged in your MG MG4 expecting fast charging, but the kW reading is disappointingly low. This is one of the most common frustrations for MG4 drivers, and it usually has a straightforward explanation. Here is what to check and how to get closer to the 142kW DC maximum your car supports.

Symptoms

  • DC charging power showing well below 142kW on the charger display
  • AC home or destination charging stuck below 11kW
  • Estimated charging time much longer than expected
  • Battery percentage climbing very slowly after 60-70% SOC
  • Charging power drops significantly in cold weather

What to Do

  1. 1

    Check the charger's rated power

    Look at the charger label or app to confirm its maximum output. If it is a 50kW unit, your MG4 cannot charge faster regardless of its 142kW capability.

  2. 2

    Check your battery temperature and SOC

    On the MG4's instrument cluster, check your current state of charge. If you are above 70%, the taper is normal. In cold weather, use the preconditioning feature by setting the charger as your navigation destination.

  3. 3

    Activate preconditioning via navigation

    Set the fast charger as your destination in the MG4's built-in navigation. This triggers battery preconditioning, warming the pack to an optimal temperature before you arrive.

  4. 4

    Try a different CCS2 stall

    If the charger has multiple stalls, power may be shared between them. Try an adjacent stall or wait for other cars to finish. Some charging sites have dedicated high-power stalls.

  5. 5

    Check your AC charging cable

    For AC charging, make sure you are using a cable rated for at least 11kW (3-phase, 16A). A single-phase cable limits you to about 3.6kW regardless of what the charger or car supports.

  6. 6

    Verify no charging limit is set in the car

    In the MG4's settings, check if a charging current limit or maximum SOC limit has been set. A reduced AC charging current setting will cap your speed even on a capable charger.

Common Le Plein Issues

App and charger interface only in French

The Le Plein app and the charger screen interface are primarily in French. If you do not read French, navigating menus and understanding error messages takes extra effort.

Symptoms

  • The app menus, buttons, and instructions are entirely in French
  • The charger screen shows an error message you cannot read
  • You cannot find the 'start session' button because the labels are in French
  • Support articles and FAQ in the app are in French only

How to Fix It

  1. 1

    Learn the key French charging terms

    A few words go a long way. 'Démarrer' means start, 'Arrêter' means stop, 'Brancher' means plug in, 'En charge' means charging, 'Disponible' means available, 'Hors service' means out of order. With these, you can navigate most screens.

  2. 2

    Use your phone's translation feature on the charger screen

    Most smartphones can translate text from a photo. Point your camera at the charger screen and use Google Translate, Apple Translate, or a similar app to read the message. This works well for error messages you do not recognize.

  3. 3

    Set up the session flow before you arrive

    Open the Le Plein app at home and familiarize yourself with the session flow: find station, select charger, start session. Once you know where the buttons are, the French labels matter less.

  4. 4

    Use your phone's built-in app translation if available

    On Android, you can translate app interfaces using the system translation feature. On iOS, you can take a screenshot and translate it. This helps with menus and settings you need to navigate once.

RFID card ordering process through the app

Le Plein RFID cards can only be ordered through the app. There is no option to buy one at a station or from a retail location. The ordering and activation process has a few steps that can trip people up.

Symptoms

  • You want an RFID card but cannot find where to order it
  • You ordered a card but it has not arrived after the expected delivery time
  • Your RFID card arrived but does not work at the charger
  • The app says your card is active but the charger does not recognize it

How to Fix It

  1. 1

    Order the card through the Le Plein app account section

    Open the Le Plein app, go to your account or profile settings, and look for an RFID card or badge option. Follow the ordering flow, which will ask for your delivery address. Delivery takes several business days within France.

  2. 2

    Activate the card in the app after it arrives

    When the card arrives, you may need to activate it in the Le Plein app by entering the card number or scanning it. Check the instructions that came with the card. An unactivated card will not start a session.

  3. 3

    Make sure your payment method is valid

    The RFID card charges sessions to the payment method saved in your Le Plein account. If your saved card has expired or been declined, the RFID card will not work even though it is activated. Update your payment details in the app.

  4. 4

    Use the app to start sessions while waiting for the RFID card

    You do not need the physical RFID card to charge. The Le Plein app can start sessions directly. Use the app until your card arrives and is activated.

Station coverage concentrated in certain French regions

Le Plein's network does not cover all of France equally. Some regions have good coverage while others have very few or no stations. This can be a problem on longer trips.

Symptoms

  • The app shows no Le Plein stations along a section of your route
  • Stations are clustered around certain cities but absent in rural areas between them
  • You planned a trip assuming Le Plein coverage and found a gap
  • The nearest Le Plein station is far from your destination

How to Fix It

  1. 1

    Check Le Plein coverage along your entire route before departing

    Open the Le Plein app and trace your route on the map. Look for gaps where there are no stations for long stretches. Identify these gaps before you leave, not when your battery is low.

  2. 2

    Install backup charging apps for other French networks

    France has several other charging networks, including Ionity, TotalEnergies, Fastned, and local operators. Having apps for two or three networks ensures you always have a fallback when Le Plein coverage runs out.

  3. 3

    Use a roaming RFID card for multi-network access

    A roaming card from Chargemap or another aggregator can access chargers from multiple French networks. This is especially useful in areas where Le Plein has no presence.

  4. 4

    Plan with a multi-network route planner

    A Better Routeplanner (ABRP) or Chargemap show stations from all networks. Enter your vehicle and destination to get charging stops that work regardless of the operator.

Charger screen errors you cannot decipher

When something goes wrong at a Le Plein charger, the error message on the screen is in French. If you do not understand the message, you cannot tell whether to retry or move on.

Symptoms

  • The screen shows an error code or message in French after you plug in
  • The charger stopped mid-session and the screen displays a French message
  • You see 'Hors service' or 'Erreur' but do not know the specific problem
  • The screen shows instructions you cannot follow

How to Fix It

  1. 1

    Photo-translate the error message

    Take a photo of the screen and use Google Translate's camera feature or Apple Translate to read it. This gives you the specific error, not just a guess.

  2. 2

    Know the most common French charger errors

    'Hors service' means out of order, do not wait. 'Erreur de communication' means a communication error between charger and vehicle, try replugging. 'Session en cours' means a session is already active, possibly from a previous user who did not end it. 'Veuillez patienter' means please wait.

  3. 3

    Try unplugging and reconnecting

    Many charger errors clear themselves when you unplug, wait 30 seconds, and plug in again. This resets the communication between your vehicle and the charger.

  4. 4

    End any stuck session in the Le Plein app

    If the charger thinks a session is still active from a previous user, you may not be able to start a new one. Check the app to see if there is an active session on that charger. Sometimes you need to wait for it to time out.

  5. 5

    Move to another charger if the error persists

    If the same error appears after two or three attempts, the charger likely has a hardware or software issue. Try another charger at the same station, or drive to the next Le Plein or alternative station.

Support phone line in French only

Le Plein's support phone line is staffed by French-speaking agents. If you need help at a station and do not speak French, communication can be difficult.

Symptoms

  • You called support and the agent speaks only French
  • The automated phone menu is in French with no language option
  • You cannot explain your problem over the phone
  • You need urgent help at a station but cannot communicate effectively

How to Fix It

  1. 1

    Try the app's support or help section first

    Written support through the app (email, contact form, or chat) gives you time to use a translation tool. Type your question in English, translate it to French, and paste it. This is often more effective than a phone call.

  2. 2

    Prepare a few key phrases in advance

    If you may need to call, have these ready: 'La borne ne fonctionne pas' (the charger is not working), 'Le câble est bloqué' (the cable is stuck), 'J'ai besoin d'aide' (I need help), and the station number or location name.

  3. 3

    Use a real-time translation app during the call

    Google Translate's conversation mode can translate speech in both directions. It is not perfect, but it helps bridge the gap. Open it before you call.

  4. 4

    Ask a nearby person for help if available

    If you are at a station and someone nearby speaks both French and your language, asking for a quick translation assist is perfectly reasonable. Most people are happy to help.

Le Plein App Tips

  • Familiarize yourself with the Le Plein app at home before your first charging session. Walk through the menus so you know where to find stations, start a session, and check your history.
  • The app shows real-time charger availability. 'Disponible' means available. 'Occupé' means occupied. 'Hors service' means out of order.
  • Screenshot or save the station details (address, charger ID) before you start driving. If you lose signal at the station, you still have the information you need.
  • Check the app for your charging history and receipts. Each session shows energy delivered, duration, and cost.

Payment Tips

  • The Le Plein app is the fastest way to pay. You can start a session in the app without waiting for an RFID card to arrive.
  • RFID cards must be ordered through the app and shipped to a French address. If you are visiting France temporarily, use the app for payment instead.
  • Make sure your saved payment card supports international transactions if you are from outside France. Some banks block foreign pre-authorization charges unless you notify them.
  • Le Plein pricing is per kWh. The rate is displayed in the app before you start. Check it, as rates can change.
