Auris Boot Leak But Dont Think Its The Light Cluster

[justinbarrow]

Hi Everyone, I have sprung a leak in my 2007 Auris I have checked the notorious rear light cluster seal and it doesn't seem perished and I ran some silicone around the edges of this seal but still leaking. When i cover the light cluster up with a plastic bag no water comes in so I know its coming from the cluster, however when I pour water on the car near to the light cluster and look inside I can see the water seeping in from a grommet, I've attached the picture and wanted to ask can this be the issue as I haven't read anything about this grommet causing this type of leak? it seeps in from the bottom of this grommet as well and not the top. 

I gather the seal is doing its job on the light cluster but finding its way round and running down behind the bumper where this grommet is located and then coming into the car from here.water is running.

If the seal was failed on the light cluster would it cause the water to come in from this grommet? in other words if the seal fails does the water come in from where the bulb holders are at the back of the cluster - Thanks for any advice everyone.

Check the vents behind the rear bumper

Thanks frostyballs I checked and water isn't coming in from the vents but can see it seeping in from the grommet in the picture, nightmare 👍
