Catalytic Converter Issues
I have an 03 Cl with 45K and I have a serious rattle in the cats. What is my best solution? Shouldn't these have lasted longer than 45K miles and will they be covered under warranty? I think if I have to spend the money for new ones I will just invest in something better than OEM. Any advice would be appreciated.

cats question
Thanks! This is my first Benz and I am not sure what is covered and what isn't and I get very vague answers from MB when I ask questions concerning things that will potentially cost them money.

Ridiculous
I have to vent! I got my car back from MBZ without them replacing the cats because they wouldn't rattle for em. But before I took it in they were rattling for about the past month. I drove the car home, went to the gym, and they are rattling again! Two days after getting the car home...it's going back in. This is ridiculous. They are telling me I have to duplicate the sound for them. I let the service guy hear the rattle over the phone but he said only if it does it when it comes in. How do I reproduce the rattle...get the engine REALLY hot?

rattling
Yeah that's what I am trying to do but the rattling is so random and this isn't a daily driver car. My dealership is about 35 miles away and I have to deal with Washington DC traffic so...not an easy thing to do! I'm taking it tomorrow after work and I am going to run the pi$$ out of her . MBZ will not cover replacing the cats under warranty once I modify, I checked. SUCKS.

Finally!!!
Well one cat has been replaced and now she is going in for the exhaust hook-up. I purchased used Eisenmann race mufflers off of this forum and I just dropped her at the Kleeman shop this afternoon. I did a couple of things to her first. I bought an AMG trim piece for the bumber($89) and cut the rear fascia so it would fit nicely...small cutouts, nothing major. The little trim piece needed to be custom fit but it was easy with a Dremel tool and a couple hours of sizing it up and sanding. I expect the shop to charge me about $180 for the muffler job. They are a little steep but the job will get done right! Hopefully I will get her back in a couple days and can share the new pics and sound with everyone. I cannot wait.
