Did the same as this guy. Reset the fault code on safety / airbag menu but light still on. No fault code showing in c110+ now.

Can anybody tell me what I’m doing wrong? Error code was 93E7 undervoltage

Thanks

So found another fault code. 990f seat belt buckle short circuit. Does anybody know what this means in real terms?

Thanks
