Yes it might be a catalytic converter. Does it sound like there are marbles ratting around against metal in that area? There is a 8 year 80,000 factory warranty on those so you might be just in time.
Yes, any dealer should honor that and you don't have to be the original owner. You obviously beat the 80,000 miles; now check to see how many years your car has been in service (start from original date of purchase). If it's less than 8 years you're in luck!Is that honored at any dealership? I am the 2nd owner and did not purchase it from a mb dealer. I have an idy mech. and have never had it to the local dealer here.
Like Ohlord said, ask the dealer anyway even though you are over the years "limit". If you were over on the mileage too, that might be different. I think you can only harm other parts of your engine if it is completely plugged up. I think you are only causing a little more pollution by driving it in that condition, but wait for Ohlord's answer to that.april 9th 1999 the vehicle was registered as a personal vehicle in Illinois. sounds like I will be reading the post on changing converters soon. But I will probably wait untill it fails completely. Any harm in doing that?
