airbag light - fail
handbrake - fail (12%

excessive corrosion

The tester identified a small hole in the O/S sill, just under the drivers door.
My mate had a look for me and this is what he found after removing the rubbery seal stuff and grinding back the crap
Not exactly the small hole I was expecting to find, I think the weather seal had lifted and water was sitting between it and the metal, the inside of the sill actually looks pretty good.
Its being welded up in the morning and the handbrake adjusted properly, I sorted the airbag light by unplugging/reconnecting the connectors like a man possessed and now have clean contacts.
Ho-hum, thank god for free retests !!!
