BMW iX Charging at Mer

BMW iX Charger Won't Start? Fix It Step by Step

You've connected the CCS2 cable to your BMW iX's right rear charge port, tapped your card or waited for Plug & Charge, and nothing happens. It's frustrating, especially with the iX's premium tech. Most of the time, the fix is straightforward.

Symptoms

• CCS2 cable is connected at the right rear port but the charger shows no vehicle detected
• iDrive 8 display shows plugged in but no charging session starts
• Charger screen shows an error code after authentication
• Charge port LED on the iX blinks or stays in an error state
• My BMW app shows the vehicle is connected but not charging

What to Do

1. 1

   Remove and firmly reseat the CCS2 connector

   Press the release button on the connector, pull it out completely, and inspect the pins. Align it straight with the iX's right rear charge port and push firmly until you hear and feel the click. The charge port LED should respond.

2. 2

   Check the charge port LED for status

   A blue pulsing LED means the iX is ready and waiting for a session. Amber or flashing means an issue on the car's side. No LED response suggests the cable isn't making contact. Check the My BMW app for specific error messages.

3. 3

   Turn off any active charging schedule

   On the iDrive 8 display, go to charging settings and look for active schedules or departure times. Switch to immediate charging mode. You can re-enable the schedule after you leave the public charger.

4. 4

   Authenticate manually if Plug & Charge didn't work

   Don't wait for Plug & Charge to magically start. Open the charger operator's app and start the session manually, or tap your RFID card on the charger's reader. If using BMW Charging in the My BMW app, start the session from there.

5. 5

   Reset the charger or try a different unit

   Use the charger's stop button, unplug, wait 30 seconds, and try again. If the station has multiple chargers, move to a different one. Some stations have two CCS2 cables on one unit. Try the other cable.

6. 6

   Move to another charging station if nothing works

   After two failed attempts, the charger is likely faulty. Use iDrive 8 or the My BMW app to find the next nearest CCS2 station. Report the broken charger through the network operator's app.

BMW iX Charging Payment Failed? Get It Working Now

The CCS2 cable is connected to your BMW iX, but the payment isn't going through. Plug & Charge didn't activate, the app shows an error, or your card was declined. This happens more often than you'd expect, and there's usually a quick workaround.

Symptoms

• Plug & Charge doesn't automatically start the session when you connect the cable
• BMW Charging in the My BMW app shows a payment or authorization error
• The charger screen says payment declined or authentication failed
• Your RFID card gets no response from the charger's reader
• Contactless bank card payment is rejected at the charger terminal

What to Do

1. 1

   Verify Plug & Charge is activated in the My BMW app

   Open the My BMW app on your phone, go to the charging section, and check Plug & Charge settings. Make sure it's turned on and linked to a valid payment method. If you see a setup wizard, complete all the steps.

2. 2

   Update your payment card in BMW Charging

   In the My BMW app, find your BMW Charging account settings and review the stored payment method. If your bank card was recently replaced or renewed, update the details. Allow a few minutes for the change to sync.

3. 3

   Identify the charger operator and use their app

   Look for the operator's logo on the charger (Ionity, Shell Recharge, Allego, etc.). Download their app, register, add payment details, and start the session directly. This bypasses BMW Charging entirely.

4. 4

   Try an alternative payment method at the charger

   If you have another RFID card, try it. Check if the charger has a contactless card reader, usually a small terminal near the screen. Try your debit card if your credit card was declined. Some chargers accept multiple card networks.

5. 5

   Move to a different charger or station

   If payment fails on one unit, try the next charger at the same station. If the entire station is problematic, use iDrive 8 to navigate to the nearest alternative. Filter by your preferred charging network for easier payment.

BMW iX Charging Too Slow? How to Get Full Speed

Your BMW iX xDrive40 supports up to 150 kW DC fast charging, which is solid but not the fastest in its class. Getting close to that peak takes the right conditions. Here's what to check when your iX charges slower than expected.

Symptoms

• DC charging power stays well below 150 kW at a high-power charger
• The iDrive 8 display shows charging speed dropping early in the session
• AC home charging limited to 3.6 kW instead of the expected 11 kW
• Estimated time to full charge is much longer than the iX should need
• Battery preconditioning indicator doesn't appear when navigating to a charger

What to Do

1. 1

   Always route to chargers through iDrive 8 navigation

   Enter the charging station in iDrive 8 as your destination or a waypoint. The iX will start battery preconditioning automatically. You'll see a snowflake or battery icon indicating the system is active. This is the single most effective way to improve charging speed.

2. 2

   Plan charging stops for lower state of charge

   Aim to arrive at DC chargers between 10% and 20%. The iX xDrive40 with its 71 kWh battery will charge from 10% to 80% significantly faster than from 40% to 100%. Use iDrive's range display to plan your arrival percentage.

3. 3

   Choose a charger rated at 150 kW or higher

   Check the charger's rated power before driving there. The My BMW app and most charging maps show maximum power per station. For the iX xDrive40, any charger rated 150 kW or above will let you hit your car's maximum.

4. 4

   Pick an isolated stall when possible

   If the station has pairs of chargers sharing a power cabinet, choose one where the adjacent stall is empty. Look at the physical layout. Stalls labeled A and B on the same unit typically share power.

5. 5

   Verify your home AC installation supports three-phase

   Check with your electrician whether your home has three-phase power. In the My BMW app, monitor your AC charging session. If it stays at 3.6 kW, you're on single-phase. Upgrading to three-phase triples your home charging speed to 11 kW.

6. 6

   Stop DC charging at 80% and keep driving

   The iX's charging curve slows dramatically above 80%. On a road trip, it's almost always faster to charge to 80%, drive to the next station, and charge again rather than waiting for the last 20%.

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.
