Our old light blue Jazz suffered similar issues with a harsh juddering or grain ching coming from the left, & after a local mechanic checked for movement in the engine mounts, we determined the gearbox needed serious work or replacement & sold as spares or repairs for peanuts.
If this information saves someone from scrapping a good car, or spending a fortune on a recon gearbox, then it's worth letting as many CVT Jazz owners as possible know about it.
