OBD connection triggers safety warnings on dashboard on Vauxhall Combo Life

Bug Reports

I'm having quite a significant issue with OBD live data.

I have just bought an OBDLink CX adapter and linked it using ABRP. I've updated the OBDLink to the latest firmware.

My vehicle is a Vauxhall Combo Life Electric 2024 (the same as the Opel Combo Life Electric / Citroen e-Berlingo / Peugeot e-Rifter).

ABRP gets the battery data, but the vehicle is showing error messages on the dashboard: e.g. "Collision Detection System not available", "Lane keeping Assist not available", and occasionally "ESP/ASR system fault: Repair needed". These only appeared after using the OBD adapter, and can appear within a few seconds of connecting to ABRP, or many minutes.

A couple of times the vehicle seemed to "reset" itself: flashing the headlights, and clicking of relays, and then resetting all the controls as if it had just been turned on. All my tests so far have been with the vehicle stationery, with the "ignition" turned on (traction battery enabled). But I'm reluctant to use the device while driving, given the symptoms.

I have tried a different OBDLink CX adapter, which gives the same errors.

I've tried connecting using other OBD apps. I've found I can provoke a similar (but not identical) error using the "Car Scanner" app. If I do a scan of "Diagnostic trouble codes", or "ECU identifier", then in each case when it gets to the ABS system, I get the same "Collision Detection System not available" error on the dashboard, every time.

So speculating, I'm wondering if the communications over OBD are interfering with the safety system from successfully communicating with one of the systems (e.g. ABS)?

I've had a look at the PIDs, and they seem to match what I've found in various forums. (I'm not an expert on OBD or PIDs).

Where does this happen?

    I have a E-Berlingo of 2025. I have the same issue. i have used first a cheap obd plug. My dashboard go out and on. and get messages on my dashboard of safety issues. Then i bought a OBDLink CX and have still the same problem. I think the OBD PID regulation is wrong for this type of cars. Unfortunately the Enode connectivity is not good for this car. So no option to use ABRP with a Citroen E-berlingo.

    Thanks for the detailed report! We have not heard of others with this issue, so we don’t know if it is a general issue or something specific for your car.
    If you want, there is the OBD PID Editor at the bottom of the vehicle settings in ABRP where you can modify the PIDs we send. Try removing some of the init commands and see if it makes any difference, for example.
