Sunroof leak into cabin. Diagram / picture wanted

Rover 75 cdti Tourer 2004.



I have had a good look round posts and the net but cannot find a picture showing the drain points on the sunroof and their piping to outside. Can you help?



Suffering water flood in drivers floor well and separately into the rear passenger well behind the driver.



Looking into the sunroof frame there are two drainage holes front right and front left corners. Front left drains nicely to the nearside front wheel arch without water in the passenger side floor. Front right hole drains nicely into the drivers floor and does not make it to the outside. Well known problem with break presumably at the front bulkhead. I need to get a clever person to do a fix. Have removed offside front wheel arch liner and snipped the strange spout so no muck. Confirmed with a piece of stiff 'strimmer line' that the pipe is disconnected inside - hence the flood.



The rear compartment is more of a problem. If I pour water into the sunroof offside gutter I get no water coming from rear offside drain whose pipe I have traced. Water just gushes down the door post inner, between front and rear offside doors. Roof lining gets wet.



First struggle is to understand where the holes are in rear of sunroof and whether pipes join together before draining to vehicle offside rear. Hence diagram need. I cannot find a nearside pipe draining at the rear.



Advice please as I'm guessing inner headlining will need to come off to locate and cure leak. Could I 'rod' it somehow or is a break likely as per front drainhole problems?



To confirm front plenum completely clear, drain pipes clean.



Obliged for help please.
