cheers thats not what i wanted to hear, i think after all that its coming where i sealed it with silicon under the mesh not sure how maybe i broke the seal when i removed the mesh and its getting between there as i felt a drop from inside the car putting my hands up to the mesh, thanks again guys, only pet hate with mk 2s everyone i have had has leaked everywhere till i sorted them out!
Oh how the hell can it get from the rear lights to passenger footwell that is bizarre!
