Plenum Drains Location

[Righthammer]

I am experiencing a leak in passenger footwell in a B7 2011 1.6 tdi blumotion .I realise that this was a common problem in the b6 model but cannot see anyone else with this issue in a B7.Can anyone point me to the location of these drains in the B7 as would like to check and clear these as the most likely cause of the leak .Door drains appear fine and there is water ingress near the pollen filter..
