2.5 v6 tdi gearbox fill plug location.

[Leigh1984]

Hi guys, new to the group so I’ll start firstly by saying hi to you all. I’m trying to locate the gearbox oil fill plug on my 2.5 v6 Passat, it’s a b5.5 and believe it is running the dsq box. It has a slight whine which speeds up and slows down with vehicle speed so thought I’d try topping up the oil before I go down the route of diff bearings. Any help is greatly appreciated. Leigh.
