Airbags & presafe warning

Anyone know the remedy for repairing intermittant airbags & presafe warning messages. Seatbelt also tensions & retensions periodically?

The ability to sense ghosts is a somewhat common birth defect caused by transient signals.

You can mess with everything except airbags and safety.

"Presafe being unstable and seatbelt tensioners are somewhat related to jumpy radar sensor but I dont see where airbag fit in. They are usually trouble free on a separate network.

Pls scan your car to retrieve the list of faulty modules.

The W203 and W204 C-Class are known to have problems with the seatbelt latch wire that breaks. When it breaks, it will trigger the airbag light. Not sure if it also disables other features. Search YouTube for how to replace the latch. That may solve the problem.
