No one answered, but problem has been resolved by the looks of it. In my case the connector under passenger seat made both of those fault codes spit out. If anyone ever has a problem with airbag lights in a 2008 touran this might be your problem.
What i did was check vcds for fault codes, airbag lights persisted, turned airbag off with switch in glovebox, cleared fault codes and they dissapeared. Turned airbag switch on again they they came back, unscrewed 4 m10 bolts for passenger seat, lifted seat carefully, unplugged and squirted contact cleaner (isopropal alcohol) into both ends female and male, plugged back in and fault codes were gone.
