C32
Catalytic Convertor
My dealer in the UK, Greanoaks Slough, tells me that my Cats are rattling (I can't hear it). They tell me that when the cats break up then the engine will ingest the particles severely damaging the engine. The local shop around the corner tells me not to worry until are really loud. Thoughts? Is Greenoaks trying to rip me off? My C32 has 93k miles.

since the cat is downstream of the engine, the only thing that will happen to the particles is they will end up coming out of the tail pipe. you have no reason to worry. also, unless you're running really rich or really lean the cats probably last forever.

The engine pushes air out and not in, so don't listen to some one who is telling you that engine will suck in things from your cats. That's rediculous
