The OP can get a V.W dealer to look at their parts list for this engine, but asking for a repair estimate is easier? The question for this engine: Is the RH engine mount a bolt on part easily replaced, or is it made integral with an engine casing part? If the former, relax, if the latter a significant part of the engine may need to be replaced . If it's the main engine block, a complete engine used or otherwise is required = car probably beyond economic repair.
If a garage isn't at fault and has been working on the car they can tell the OP whether the engine mount is replaceable or is part of a larger more expensive engine component?
In UK the annual test would fail this car for a broken engine mounting and it wouldn't legally be allowed on the road. It's sad to see a car with a serious problem like this. A close examination of the shear/tear/break/ would show how it might have happened. It doesn't look like a single fracture, manufacturing defect, or corrosion, from the photos, which is why I think it's been damage by bad workshop practice or suffered an impact of some kind?
