[b][u]Wet head lining and passenger footwell[/u][/b]..Tried to unblock front sunroof drains (from top) with 2.5mm copper wire.As suggested in a forum on here.
Found that i could hear wire rattling down A pillar(passenger side),which suggested drain hose had come off.
This is how i tackled it..
1)Remove all fixtures on head lining,and drop rear seats.
2)Take out 2x plastic clips from strip at back where head lining meets top of hatch/boot.Then from back of car pull strip out and down clear of rubber seal.
