hi there was wondering if anyone knows what the common faults are for the airbag light staying on,it just popped up one day ,now i cant get a warrant because of it,also it seems to be using water , around about a litre every 50kms i had to replace water res tank as it had a crack in it,but still seems to use water,anyone that can help on these matters would be greatly appreciated
