Tiptronic: 4-Cylinder Engine Performance

Hello,

Are the Tiptronic transmissions also used with the 4-cylinder engines (including TDI models)?
Are the same components used as in the six-cylinder versions?
I'm not referring to the casing itself, but rather the technology inside.
Specifically, I would like to know if they also have this intermediate drive system for three-wheeled vehicles.
My file is too old and doesn't know .

Regards,

Maciek.
