BMW i4 Charging at REWE Charging

BMW i4 Charger Won't Start? Step-by-Step Solutions

You've plugged in the CCS2 cable to your BMW i4's right rear charge port, but nothing happens. This is one of the most common frustrations at public chargers. The good news is that most causes are fixable on the spot.

Symptoms

• CCS2 connector is plugged into the right rear port but the charger screen shows no vehicle detected
• Charger displays an error code and refuses to start the session
• My BMW app shows the car is plugged in but not charging
• The charge port LED on the i4 flashes or stays amber instead of turning blue
• Authentication via app or RFID card goes through but charging never begins

What to Do

1. 1

   Unplug the CCS2 cable and reseat it firmly

   Pull the connector out completely. Check the pins for debris or damage. Line it up straight with the charge port on the right rear and push until you hear a clear click. The charge port LED should respond.

2. 2

   Check the charge port LED color on the car

   Blue pulsing means the car is ready to charge. Amber or yellow means something is wrong on the car side. No light at all may mean the port isn't detecting the cable. Open the My BMW app for more detail.

3. 3

   Disable any charging schedule in iDrive

   On the iDrive curved display, go to the charging settings and check for active schedules or departure times. Disable scheduled charging temporarily if you want to charge immediately at a public station.

4. 4

   Try authenticating again or use a different method

   If Plug & Charge didn't start the session, open the charging network's app and start manually. If the app fails, try an RFID card. If you're using BMW Charging, check that your payment method is current in the My BMW app.

5. 5

   Restart the charger if possible

   Some chargers have a stop/reset button on the screen. Unplug, wait 30 seconds, and try again. If the charger has two cables, try the other connector. Check the charger's screen for error messages or an out-of-service notice.

6. 6

   Move to a different charger if the problem persists

   If nothing works after two attempts, the charger is likely faulty. Use the My BMW app or a charging map to find the next nearest station. Report the broken charger through the network's app to help other drivers.

BMW i4 Charging Payment Failed? How to Fix It Now

You're at the charger, the CCS2 cable is plugged into your BMW i4, but payment won't go through. Maybe Plug & Charge didn't kick in, the app is throwing errors, or your card was declined. Here's how to sort it out and start charging.

Symptoms

• Plug & Charge doesn't activate when you connect the CCS2 cable
• BMW Charging shows a payment error in the My BMW app
• The charger screen says authentication failed or payment declined
• Your RFID card is not recognized at this charging station
• Contactless card payment at the charger terminal is rejected

What to Do

1. 1

   Check if Plug & Charge is set up in the My BMW app

   Open the My BMW app, go to your charging settings, and verify that Plug & Charge is enabled and linked to an active payment method. If you see a setup prompt, complete it before trying again.

2. 2

   Update your payment method in BMW Charging

   In the My BMW app, navigate to your BMW Charging account and check your stored payment card. Update it if it's expired or recently replaced. The change should take effect within a few minutes.

3. 3

   Try the charging network's own app

   Identify which company operates the charger (the logo is usually on the unit). Download their app, create an account, add a payment method, and start the session through their app instead of BMW Charging.

4. 4

   Use a different RFID card or contactless payment

   If you have another RFID card from a different network, try that. Some chargers also accept contactless debit or credit cards. Look for a payment terminal on the charger, usually near the screen.

5. 5

   Try a different charger at the same station or a nearby station

   Sometimes a single charger's payment terminal malfunctions while others work fine. Try the next unit over. If the whole station is problematic, use iDrive navigation to find an alternative station nearby.

BMW i4 Charging Slower Than Expected? Fixes Here

Your BMW i4 eDrive40 supports up to 205 kW DC fast charging, but real-world speeds often fall short. Several factors specific to the i4's 80.7 kWh battery and 400V architecture can limit charging power. Here's how to diagnose and fix slow charging on your i4.

Symptoms

• DC charging speed stays well below 205 kW even at a high-power charger
• Charging curve drops sharply before reaching 60% state of charge
• AC charging at home or destination chargers maxes out at 3.6 kW instead of 11 kW
• iDrive curved display shows a lower charging rate than the charger's rated output
• Estimated charging time on the iDrive screen is much longer than expected

What to Do

1. 1

   Use iDrive navigation to route to your charging stop

   Enter the charging station as a waypoint or destination in iDrive. The i4 will automatically precondition the battery while you drive, warming it to the ideal temperature for fast charging. This alone can double your charging speed in cold weather.

2. 2

   Arrive at the charger with a lower state of charge

   The i4 charges fastest between 10% and 50%. If possible, plan your stop so you arrive closer to 10-20%. The difference between arriving at 15% versus 50% can save significant time.

3. 3

   Choose a charger stall that isn't sharing power

   Look at the charger setup. If two CCS2 cables come from one cabinet, pick a stall where the neighboring connector is free. Some stations label paired stalls with A/B designations.

4. 4

   Check your AC charging setup at home

   Open the My BMW app and look at the charging details during an AC session. If you're only getting 3.6 kW, your installation likely provides single-phase power. Ask your electrician about a three-phase connection to unlock the full 11 kW.

5. 5

   Check the charging status on the iDrive curved display

   While charging, the iDrive screen shows current power, estimated time remaining, and battery temperature. If power is low and battery temperature is also low, the car is still warming the pack. Give it a few minutes to ramp up.

6. 6

   Unplug at 80% and drive to the next charger if needed

   Charging from 80% to 100% on DC can take as long as 10% to 80%. On road trips, it's almost always faster to charge to 80%, drive, and stop again rather than waiting for a full charge.

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.
