1. What does P0CE100 mean?
For a 2020 Audi Q5 in the US, DTC P0CE100 is documented in Audi service communications as a code that may be stored in the thermal management control module. Audi’s documented production solution is updated software for thermal management control module J1024 (address word 00C5).
2. Technical explanation
Verified Audi service-bulletin evidence identifies P0CE100 in connection with a MIL-on condition and storage of the code in the thermal management control module. The bulletin states that new software in thermal management control module J1024, address word 00C5, addressed the condition. For vehicles with high-voltage components, the bulletin specifically requires preventing high-voltage-battery charging during the software update by removing the high-voltage cable before entry of the SVM code. The source excerpt does not establish further diagnostic root-cause details.
3. What system is affected?
Thermal management control module J1024 (address word 00C5), with bulletin-specific precautions for vehicles with high-voltage components.
4. How serious is this code?
Not yet established by verified evidence. The supplied evidence documents a MIL-on condition and a software-update procedure but does not assign a severity level.
5. Symptoms you may notice
- MIL on.
- DTC P0CE100 stored in the thermal management control module.
6. Possible causes
- The verified bulletin indicates that software in thermal management control module J1024 addressed the documented condition.
- A more specific underlying cause is not yet established by verified evidence.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
Not yet established by verified evidence. The bulletin states that the high-voltage battery must not be charged during the specified software-update procedure.
9. What you can safely do
- Arrange diagnosis by an Audi-authorized service facility or a qualified technician with the appropriate Audi diagnostic and software-update capability.
- Do not attempt the bulletin’s high-voltage cable removal or software-update procedure yourself.
- If a software update is performed, follow the manufacturer procedure that prevents high-voltage-battery charging during the update.
10. Step-by-step troubleshooting
- Confirm whether P0CE100 is stored in the thermal management control module.
- Check whether the vehicle is within the documented applicability: 2020 Audi Q5, US.
- Have a qualified service facility evaluate applicable software for thermal management control module J1024, address word 00C5.
11. When to contact service
Contact an Audi-authorized service facility, particularly if the MIL is illuminated and P0CE100 is present. The verified service information identifies a control-module software solution and includes high-voltage charging precautions during that update.
12. What the service center may check
- Scan the thermal management control module for P0CE100.
- Determine whether the applicable software update for J1024 (address word 00C5) is available.
- During the documented update on a vehicle with high-voltage components, prevent high-voltage-battery charging as specified by Audi before SVM-code entry.
13. Possible repair or resolution
- Audi’s documented production solution is new software in thermal management control module J1024 (address word 00C5).
- The precise repair outcome for an individual vehicle is not yet established by verified evidence.
14. Affected vehicles
- Audi Q5 · 2020 · US
