I had a similar recall done on our '98 E320. It said (quoting):

Perform Action 00-1002, subsequent coating of both front longitudual members.
CAUSE: 00-1002
023206 Perform Action 00-1002, Subsequent coating of rocker panel
2 W 0.70 N/C
1 000-986-68-70-10 SEALING CAVITY

This sounds like same or similar tsb.

Can any one decode this and explain just what was done - I asked advisor, but did not get a very clear answer.
