Maybe this will help:

1985 California wagon (300TDT), bought by me 3/89 in Los Angeles with 58K miles and owned by me since. I do all the regular maintance but took the car to the dealer at the regular 30K mile services to get trap replaced. I have every service record from when the car was sold new in 10/85, including records of my own work.

90K mile service on 3/96: replaced trap oxidizer with same (called "soot filter", P/N# 617-142-02-94)

120K mile service on 11/00: replaced trap oxidizer with catalyst (called "catalyst", P/N# 126-490-34-14). Service invoice reads, "replace trap oxidizer with an oxidation catalyst as per MBNA service campaign bulletin #96-1121, D.C. 0 14355 53 7.

All trap related service was done under warranty. The turbo and exhaust systems were not replaced as they were (and are still) in good shape. I verified with the service manager at 150K miles that the new catalyst did not need to be replaced. Note that the new and old traps look exactly the same. On the OM617 (unlike the 603) engines if there is a visual difference between the two traps it is very minor.

Hope that answers your questions.
