2006 Audi A4 Avant - Leaking Water In Passenger Footwell

[RJ_Head]

Hi everyone. I'm a little new to this but fancied joining up as I have recently purchased (within the year) a 2006 Audi A4 Avant S Line. I love the car, but as always, with an 06 reg carrying 118k miles, problems will happen!

Anyway, recently (not necessarily when it rains), water appears to leak into my passenger footwell and some times the drivers side too! I have taken the battery out & cleaned around that area, taken the glove box apart and looked for any obvious leaks but can't seem to find anything. 

Any suggestions? 

Thanks

Sunroof drains 

Rear wiper washer pipe runs there that causes a leak

Pellenium chamber drains blocked

Roofrails washers failed but you would see some water on the headliner
