The PO was my late father in law who had numerous accidents. The final repair in 1992 was from his last accident which involved a brick truck and the bill for the repair was $14K. He died from old age not the accident. Apparently the dealer neglected to install the liner. That dealer also skipped the removal of the trap oxidizer although I am not clear when MB issued the rework order.

The absence of a liner on the passenger side might explain why the air intake keeps getting debris in it. Do you happen to know the part number or if it is still available? I tried the fast lane index but could not find it.
