“Autobunkerz Brisbane repairs VAG airbag modules damaged by water from blocked A/C drains. Fix VW and Audi airbag warning lights safely and cost-effectively without full replacement.”

About This Fault

One of the most common reasons the airbag warning light stays on in Volkswagen and Audi vehicles is water ingress into the airbag module, often caused by a blocked A/C drain.

When water collects in the passenger footwell, it can seep into the airbag control unit and damage internal electronics. This can result in:

• Continuous airbag warning light

• Seatbelt pretensioner errors

• Communication faults in diagnostics

At Autobunkerz Brisbane, we specialise in diagnosing and repairing water-damaged VAG airbag modules, restoring the system without full replacement.

​
