Volkswagen’s ID.4 electric vehicle has been making waves in the industry since its release. It is a compact SUV with an impressive range, quick charging times, and a sleek design.
However, some owners have reported seeing a warning message that reads “Electrical system not working correctly” on their dashboard.
This can be a concerning message for drivers, but there are several reasons why this warning may appear.
If you’re in a hurry, here’s a short summary of the article:
“Electrical system not working correctly” might be caused by many factors, but the most popular ones are faulty sensor, OBD dongle interference, software glitches, or problems with the coolant pump.
What are the Reasons Behind the Warning “Electrical System Not Working Correctly” in the VW ID.4?
Reason 1
One of the most common reasons for the warning is a random sensor error. This can happen due to a faulty sensor or a tolerance issue.
A faulty sensor may give false readings, causing the car’s electrical system to malfunction.
In contrast, a tolerance issue may occur when the sensor’s output is within an acceptable range, but the car’s system is programmed to be more sensitive, leading to a warning message being triggered.
Reason 2
Another potential cause for the warning message is the use of an OBD dongle.
An OBD (On-Board Diagnostics) dongle is an aftermarket device that can be plugged into a car’s OBD port to monitor the car’s performance and provide data on fuel economy, engine health, and other metrics.
However, using an OBD dongle can interfere with the car’s electrical system, causing random error messages to appear.
Reason 3
The warning message can also be caused by software glitches or bugs. Since the ID.4 is a highly computerized vehicle, it is possible for software issues to arise that can affect the car’s electrical system.
However, Volkswagen has provided remote patches and software updates that can be downloaded to resolve these issues. Owners should ensure that their car’s software is up-to-date to prevent these glitches from occurring.

Reason 4
One possible cause of electrical system errors in the ID.4 is a faulty coolant pump.
The coolant pump is responsible for cooling the electric motor, power electronics, and charging unit. If the coolant pump fails, the system may overheat, triggering the error message.
Reason 5
Another potential cause of electrical system errors is a low voltage battery. The ID.4 has a 12-volt auxiliary battery that powers the car’s onboard systems.
If the battery is low or failing, it could cause electrical system errors. This issue can be prevented by regularly checking the battery’s voltage and replacing it if necessary.

Reason 6
Finally, charging issues can also trigger the warning message. The ID.4 is designed to be charged at home or at public charging stations, but sometimes charging can fail, causing the car to malfunction.
If the car is not charging correctly, it may trigger the warning message, and the car’s electrical system may not function correctly until the issue is resolved.
How to Fix This Warning in the VW ID.4?
You can try the following solutions to fix this error.
- Check the sensors: As mentioned earlier, random sensor errors can trigger the warning message. A faulty sensor or a tolerance issue can cause this. You can take your VW ID 4 to a certified technician to diagnose the sensors and replace them if necessary.
- Remove the OBD dongle: If you have an OBD dongle installed in your car, try removing it and see if the warning goes away. The dongle may interfere with the car’s electrical system and cause the warning to appear.
- Software updates: VW may release remote patches or software updates to address software glitches or bugs that cause the car’s electrical system to malfunction. Make sure your car is up-to-date with the latest software version.
- Reset the error: In some cases, instead of driving to the dealer, you just need to get out of the car and lock the doors for 15 minutes might for the warning to disappear.
- Charging issues: If the warning message appears while charging, make sure the charging cable is properly connected and the power source is working correctly. You can also try using a different charging cable or charging station to see if the problem persists.
- Consult a certified technician: If none of these steps resolve the issue, it’s best to take your VW ID 4 to a certified technician. They can perform a full diagnostic check on the car’s electrical system and identify the root cause of the problem.
- Replace the battery: If the error message is caused by a low or failing auxiliary battery, you may be able to fix the issue by replacing the battery. However, it’s important to note that this should only be done by a trained technician. Attempting to replace the battery yourself could cause serious injury or damage to the car’s electrical systems.
Summary
In conclusion, the warning message “Electrical System Not Working Correctly” in the VW ID.4 can be caused by various factors such as faulty sensors, OBD dongle interference, software glitches, problems with the coolant pump, low voltage battery, or charging issues.
To fix the issue, there are several steps that can be taken, including checking the sensors, removing the OBD dongle, updating the software, resetting the error, checking the charging cable, and consulting a certified technician.
It’s important to address this issue promptly to ensure the car’s electrical system is functioning correctly and to avoid potential safety hazards.
The VW ID.4 is a highly advanced electric vehicle that requires proper maintenance and attention to keep it running smoothly.
