Yeah I thought it was 8/100. The S430 in queston is a 2000 and this happened in 06, so it was 6 years about 40k-50k miles at the time. The egr failed or something like that causing it to run rich back from VT and it blew the cats as a result.

His mechanic brought it to the dealer, and from the way he made it sound the dealer never batted an eye. Just did the warranty work, it gets charged back to MB anyway dealers love that stuff.
