Catalytic converters are designed to last around 10 to 15 years or about 100,000 to 150,000 miles under normal driving conditions. However, their lifespan can be affected by factors such as engine performance, fuel quality, and maintenance practices. Regular vehicle maintenance and addressing engine issues promptly can help prolong the life of a catalytic converter. If you notice any signs of poor performance or a check engine light, it's important to have it inspected.

It depends on what kind of converter you purchased. If you purchased a cheap aftermarket converter, then I'd guess it wouldn't last as long as an O.E. Volkswagen one. I'm guessing that your original one lasted seven years, so I'd think that a new one should last that long. It's possible that another problem such as a bad fuel injector or a miss in the engine could cause the engine to dump raw fuel into the converter. This would considerably shorten the life of the converter. A vacuum leak could cause the same problem. It should last more that a year and a half, either way, although it's doubtful that the part will be warranted longer than that.
