Water has leaked onto air bag piston located right hand side

This answer was rated:

water has leaked onto air bag piston located right hand side of boot. Signs of heavy rust on piston. Can the piston be replaced and how much is a new piston?
JA: What part of the car is the leak coming from? And are you sure it's water?
Customer: The water is coming through the grummit on electrical cables passing through hatchback gutter.
JA: What year is your Hatchback?
Customer: reg no 11
JA: Are you fixing your Hatchback yourself? What have you tried so far?
Customer: The leak has been repaired by small garage. Garage proprietor noticed the rust on the piston and suggested I took the car to main agent for advice.
JA: Anything else you want the Mechanic to know before I connect you?
Customer: Is it necessary by law to have this air bag operational? Or can the piston be removed all together.
if the piston is damaged enough effecting the operation of the airbag causing leaks or malfunction then this can be a failure,
i woukd start by trying to seal around the gromet amd give the piston a good clean with a scouring pad and some penetrating oil. if it is heavily corroded then a replacement should be sourced. i believe you have to buy these with the bag at a total of around £150 plus 1 hour to fit.
