Has anyone had a issue with the rear seats getting wet? Seam to be coming from the boot possible the rear lights can anyone shed some light as it's starting to smell! 

Manythanks

Is your rear screen washer working OK ? as there is a production break in the pipework by the rear passenger upper seatbelt mounting point, Leaking rear lights normally just floods the boot/spare wheel well

Seams fine it sprays normal but should this be something I check? As the foam around the lights seam to be soaking wet. I have also sealed the below grommet as it looks like they have tried to seal it before

Thanks for replying! 

If the washer pipe is leaking you can normally tell as the water will have that smell of slight alcohol, (unless your not using any additives) As I said when the light seals fail it normally just fills the spare wheel well, but not getting the seats wet ?

Ah yes I see what you mean would it still leak if I didn't use the rear washer? As it's leaking from the front anyways 

I had exactly the same issue with my MK3, it was a leak in the rear washer tube. Try not using your rear washer for a while and it should dry out

Seams to be pointing that way how would I go about getting to the pipe? Should I look in the gator in between the boot or take the pipe off at the the front and not have it at all?

Unfortunately I don't know exactly what to do for your model. For me, I could access the tubes from inside the boot and didn't need to take anything apart. My rear washer hasn't worked since I got the car though, so I just disconnected it.
