Hi there new on here 

I’ve got a 2018 fabia had a small bump in the side that’s sorted now but my airbag light is on a friend plugged it in and it says all the seat belts are too low ohm could anyone please tell me the cheapest way to get rid of the light on the dash board thank you. 

Easiest way to clear the error if you dont have an OBD reader such as OBD11 or VCDS is to unplug the battery for a few minutes which will reset the ECU.  If the airbag light comes back on, you probably have an active error still ongoing and you'll need to have a garage look into it for you.

Thanks for your help I’ll try that. 👍👍👍
