That was a problem on ALL 560SL's. MB offered modified wiring harness to keep water from the CIS-E computer. MB part number 107-540-24-34. Only info is inner-office memo on the problem, never reached SI status.
The replacement numbers for the computer are 006-545-82-32 OR 006-545-96-32, orig number was 004-545-40-32.
$250 is a GOOD price
