I have change the central unit 1K0 909 605 S and in the driverseat i have 2 ohm resistanse.

 

Any solution?

It will be either the yellow connector that is found under a plastic removeable trim cover in front of the seat rail or in my case turned out to be a little known secondary connector tucked up under the seat squab.

 

Looking through the service history the car had been plagued by this fault for years costing previous owners literally thousands in unecessary work and resets including the alleged replacement of the airbag which had not been done.

I have the 2 ohm resistance in that connector you tell me aboat  infront of the rail. Maybe it can be the airbag on the sideprotesion. https://workshop-manuals.com/skoda/octavia-mk2/body/body_work/passenger_protection/airbag/summary_of_components_of_head_airbag_unit/

Actually reading carefully it says that its the crash sensor not the airbag, not sure where it is located but have a feeling it might be in the door in which case a broken wire in the hinge grommet would be a likely suspect.

Hi JR,,, yes it is the chrash sensor so now must i try to find them.
