BMW iX3 Charging at Mer

BMW iX3 Charger Will Not Start or Authenticate

You have plugged the CCS2 cable into your BMW iX3's charge port on the left rear fender, but nothing happens. No green light, no charging screen on iDrive, just silence. This is frustrating but usually fixable on the spot. The cause is almost always an authentication issue, a locked connector, or a setting in the car.

Symptoms

• CCS2 or Type 2 cable plugged in but iDrive shows no charging activity
• Charger screen shows an authentication or authorization error
• Charge port LED flashes or stays amber instead of turning green
• Plug and Charge does not activate automatically at a supported station
• Charger displays 'waiting for vehicle' and nothing happens

What to Do

1. 1

   Unplug, wait, and reconnect firmly

   Remove the cable from the charge port on the left rear fender. Wait 30 seconds. Push the connector back in firmly until you hear and feel it click into place. Watch the charge port LED for a color change.

2. 2

   Check authentication on the charger

   Make sure you have tapped your RFID card, opened the correct charging app, or confirmed that Plug and Charge is enabled in iDrive for BMW Charging. Some chargers require you to start the session from the charger screen or app before plugging in.

3. 3

   Disable any charging schedule in iDrive

   On the 14.9-inch center display, go to Charging settings and check for an active departure timer or charging window. If one is set, either disable it or switch to 'charge immediately.' The car may be waiting for your scheduled time.

4. 4

   Check for ice or debris around the charge port

   In cold weather, inspect the charge port flap and the connector area on the left rear fender for ice buildup. Gently clear any ice. Do not use sharp tools. If the port is frozen shut, use the My BMW app to try unlocking it remotely, or warm the car interior to help thaw the mechanism.

5. 5

   Try a different charger or cable

   If the charger has multiple cables, try the other one. If another charger is available nearby, move to it. Charger faults are common and switching stations often solves the problem immediately.

6. 6

   Restart the iDrive system

   If nothing works, try restarting the iDrive system. Press and hold the start/stop button for about 30 seconds with the car in park and doors closed. Wait for the system to reboot, then try plugging in again.

BMW iX3 Charging Payment Failed or Card Declined

You are at the charger, ready to plug in your BMW iX3, and the payment does not go through. Your RFID card is rejected, the app shows an error, or Plug and Charge through BMW Charging does not activate. Payment problems are one of the most common reasons a charging session fails to start, and they are almost always fixable on the spot.

Symptoms

• Charger screen shows 'payment declined' or 'authorization failed' after tapping your card
• The charging network app shows a payment error or asks you to update your payment method
• Plug and Charge does not activate automatically when you connect the CCS2 cable
• Contactless payment terminal on the charger does not respond or times out
• RFID card tap is not recognized by the charger reader

What to Do

1. 1

   Check your payment method in the charging app

   Open the charging network's app on your phone. Go to payment settings and verify that the linked credit or debit card has not expired. If it has, update it with a valid card. Some networks also show your account balance or prepaid credit here.

2. 2

   Try a different payment method at the same charger

   If your RFID card is rejected, try the network's app QR code scan or contactless bank card. If the app fails, try RFID. Having at least two different ways to pay at any charger saves time. The iX3 itself does not process payment, so this is all handled at the charger.

3. 3

   Check if Plug and Charge is enabled in iDrive

   On the curved display, go to Charging settings and look for the Plug and Charge or BMW Charging option. Make sure it is turned on and your BMW Charging account is active. If the station does not support Plug and Charge, you will need to authenticate manually.

4. 4

   Verify the charger accepts your card or network

   Look at the logos on the charger or check the station listing in your app. Not every charger accepts every RFID card or network. If yours is not listed, you may need to download the charger operator's own app and create an account to use that specific station.

5. 5

   Use the My BMW app to find an alternative nearby charger

   If payment will not work at this station, open the My BMW app or use iDrive navigation to find another charger nearby. Filter by your preferred payment network. BMW Charging shows compatible stations where your BMW account is accepted.

6. 6

   Contact the charging network's support line

   Most chargers display a phone number or QR code for customer support. If you have tried everything and payment still fails, call or message support. They can sometimes start the session remotely or identify a known issue with that specific charger.

BMW iX3 Charging Slower Than Expected at DC or AC

You plugged in your BMW iX3 at a fast charger expecting 270 kW, but iDrive shows 60 kW. Or your home wallbox is stuck at 3 kW instead of 11 kW. Slow charging on the iX3 is almost never a defect. It is usually the battery temperature, the charger itself, or a setting in iDrive you can fix in a minute.

Symptoms

• DC fast charging speed well below the 270 kW maximum shown on iDrive
• AC home charging stuck at 3-4 kW instead of the full 11 kW
• Charging speed drops sharply after reaching 50-60% state of charge
• Charging session starts at a reasonable speed but slows down within minutes
• The curved display shows lower power than the charger's rated output

What to Do

1. 1

   Route to the charger using iDrive navigation

   Enter the charging station as your destination in iDrive. This activates automatic battery preconditioning, which heats or cools the 108.7 kWh battery to the ideal temperature range before you arrive. You will see a notification on the curved display confirming preconditioning is active.

2. 2

   Check the battery temperature and charging power on the display

   On the 14.9-inch center display, look at the charging screen. If the battery temperature is shown as cold, the car is limiting power to protect the cells. Give it 5-10 minutes to warm up, or next time route through iDrive so preconditioning runs in advance.

3. 3

   Check your state of charge

   If you are above 80%, the slower speed is expected. For the fastest DC charging, arrive at the charger between 10-20% and charge to 80%. The iX3's 270 kW peak is only available in the lower state of charge range.

4. 4

   Verify the charger is not sharing power

   Look at the charger unit. If there are two CCS2 cables and someone is using the other one, you may be splitting the charger's capacity. Move to an unoccupied charger if one is available.

5. 5

   Check the AC charge current setting in iDrive

   Go to iDrive Settings, then Charging. Make sure the maximum charge current is set to the highest value. If it shows a reduced amperage, increase it. This is the most common fix for slow home charging.

6. 6

   Try a different charger or restart the session

   If the speed is still low, unplug, wait 30 seconds, and plug in again at the charge port on the left rear fender. If that does not help, try a different charger. Some chargers degrade over time and cannot deliver their rated power.

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.
