Yet they call it an eLSD...VW ERWIN, official workshop books....
Note that its states:- "It is powered by the output shaft of the gearbox via the differential"...i.e. the existing "open" type differential in the gearbox....
The way it works is to "lock" the front drives shafts & the existing open diff all together/up.....its a front axle/diff lock...& yes there are existing devices in 4x4 called "diff locks"...those purpose is to lock the axle up so that both wheels spin at the same speed especially when one is in the air.....& that is what the FXD/VAQ unit does....to stop the inside unloaded wheel from spinning by locking the the front axle & diff up by varying amounts/percentages...upto 100% lock....to drive the loaded outside wheel..(in simple terms)
Sorry but you are not thinking about this logically. You are defining a differential by "how" it does something rather than "what it does".
A limited slip differential is a solution to a specific problem: Keeping proper rotation of the wheels during a turn to maintain proper traction. Your definition "assumes" incorrectly that there is only one proper solution when there could be multiple effective solutions. A traditional mechanical LSD is only one solution to that problem and it is wrong to assume there are no other solutions that could be included as an LSD. The VW solution is an electronically controlled LSD that was designed to solve the exact same problem as the traditional LSD.
Some have argued that a traditional LSD is a better solution for higher performing cars with bigger turbos. That is only partially correct. Because the eLSD is electronically controlled it is in effect "tuned" to OEM specifications. This means the eLSD in theory could be tuned to perform as effectively as a traditional LSD for higher performing cars.
If it looks like a duck, and waddles like a duck and quacks like a duck than it is a duck. If it does the same thing as a LSD and solves the same problems as a LSD than it is a LSD...
