Air Bag light 10 seconds????

The post-recall airbag controller is much more sensitive to a number of
fault conditions, and can (and does) store faults in non-volatile
memory.  The fault-code can be cleared by anyone with a 1551 or equivalent
tool, including Ross-Tech's VAG-COM.  The diagnostic connectors for the
airbag controller should be in the center console behind the left side
panel--if you sit in the driver's seat, go directly right of your
knee--I've also heard reports of them being behind the right side panel, by
the airbag circuit connector.

Disconnecting the power will NOT clear this fault, and in fact,
jump-starting a flat battery is one potential cause of a fault (the system
needs a minimum voltage to operate).  Other reported situations that
trigger a fault code include turning on the ignition without the airbag
attached (i.e. "testing" your instrument panel repair work by turning on
the ignition with the steering wheel off or the connector in the center
console disconnected, enabling the Check Engine light where it had been
removed by swapping in the warning light for the airbag and incorrect
resistance in the spiral spring.  According to one report, tolerance for
the spiral spring resistance can be changed by recoding the controller;
unfortunately, this is not documented in the Bentley (but may be available
in a later car's manual).
