It could be any of the six airbags or the seatbelt pretensioners or something else I can't even think of so the best bet is get the error codes read, prefrrably with a Lexia. This will narrow down which item is causing a problem.

As a preliminary before doing that you could try looking for connectors in the wiring under the seats. Some Xsaras have suffered from intermittent contact in these connectors (for the seatbelt pretensioners) and umplugging and remaking sometimes fixes the problem.

Hi,

Could also be a break in one of the "flexible " leads to the steering wheel air bag.

These are not easily replaceable or removable, I think they are integral with the com2000 unit. You can gain access to the leads by removing the air bag.

However, they can be repaired in situ by carefully cutting back the plastic insulation and repairing the break by soldering.

You must disconnect the battery and allow time for capacitors etc to discharge before you remove the air bag.

Removing the air bag is a bit tricky involving two screw drivers, one inserted into each of two two slots at the back of the steering wheel and then leavering the two plastic tabs to release the air bag.

You can release the connector at the air bag end and then need to do the repair in situ.

Good luck!

In my C5 it also was accompanied by the lack of a horn whicg cost me about £300 to have the Comms unit replaced in the steering column.
