Rarther than bury my findings in another thread i started regarding this problem i decided to create a new one.Given the age of the pre facelift tourer i'm sure it will help others in future.
Having first looked at the roof seam along both sides i wrongly decided my leak originated elsewhere.I then moved on to testing for leaks on the rear windows,tailgate rubber seal,lights and bootlid hinges but i ruled all these out after much testing.
This led me back to the roof itself.I next did a check on sunroof and the four drain tubes but again no leaks.At this point there was nowhere else water could leak into the car other than from the roof area so i decided to return to the roof seams.
Now my tourer is a 2004 model with no rails although there are a series of bolts along both roof channels beneath the plastic trim.After previous inspection i found NO corrosion outside and NO visible signs of splits/cracks with sealant that bonds roof to side of car.
So with it pouring down today i decided to look again but with a little inspection mirror i made for viewing areas of engine i cant view direct.I eventually discovered a tiny weep half way along the left hand channel under a bolt weld.As it is not large leak instead of dripping striaght down it trickles along the underneath of seam above interior headliner and finally drips down at the back of car.The water then drops onto tailgate wiring loom and eventually down the back of tailgate pillar and into the little trough under the first aid cubby.This in turn fills and enters wheel well and of course if not emptied fills the area below woofer speaker.
This was a tough leak to figure out but now ive found it its an easy fix.I intend to reseal both sides as soon as the rain eases to prevent any further problems.
