If the bearing is bad it has likely scarred the crankshaft; in which case the crankshaft will need to be removed and machined. Afterwards you can purchase an "undersized" bearing (insert) for that connecting rod [if the rod itself hasn't been damaged]. This will require the engine to be removed. Also, some (a lot) of VW turbo engines require that the connecting rods are replaced in sets [all four] if one is bad (so as to keep the engine in balance, because of the higher rpm's associated with the turbo application). These are all things to consider against the cost of a new engine. HOWEVER, THE FIRST THING TO DO IS TO VERIFY THAT THE NOISE IS INDEED A CONNECTING ROD PROBLEM. This could save both money and time.
