Water drip Passat TDI AFN

Hello, I am new in this forum, so I forgive if I make any mistake or I do not explain well I have a passat tdi year 99 engine AFN with 400000 km My question is the following, do you know if that block has any plug that to access the beech to separate the field of cambios and go out there? Thanks in advance and greetings to all

In the upper part of the gearbox between the engine and the change they carry a tea of ​​the antifreeze circuit that are plastic and when they lose the antifreeze down by the registration of the point of the engine and appear where you see it. It seems to me that it does not carry any cap in the block on that side.

Thank you very much Ivacoma I will look good to see if I see where you say greetings
