there are 3 main areas holding the engine in
1 : left engine mount
2 : right engine mount
3 : lower gearbox mount
For the sake of clarity, you might like to re-edit the above - sommat along the lines of:
The engine and transmission are supported by three specific mounts (orientation when viewed from drivers seat and car in normal forward direction of travel):
- Right engine mount. OEM consists of a voided single-part rubber bush with an additional NVH viscous damper.
- Left transmission mount. OEM consists of a voided two-part rubber bush.
- Lower rear centre engine mount. OEM consists of a voided single-part rubber bush (actually two separate circular parts; upper and lower)
These rubber inserts with voids (spaces) are highly compliant, to provide a highly insulated solution making the GTI so quiet - but they also allow for a great deal of engine-transmission movement.
Of the above, the latter lower centre mount connects to the engine via an intermediate bar, aka the 'dogbone', which also contains a 'bush'.
