airbag warning light

Recently had X5 rear passenger widow actuator replaced. In the process, the airbag warning light has illuminated. The local shop doing the work claims there are no codes in the computer to reset and they seem to be stuck despite many conversations with a BMW dealership. Shop has a reputable history....has anyone experienced similar problem?

Same thing happened to me... Replaced rear window actuator and now air bag warning light goes off and on... I'll have my mechanic check this problem soon. If you find out the root cause or solution, pls update me also.
Thx.
