pifcat, the following Part Numbers are all the 8-pin variety from our 1991 and 1992 300CE's:
016 545 04 32 (1991 300CE failed EZL)
012 545 20 32 (1991 300CE replacement)
013 545 83 32 (1992 300CE original)

Our local indie explained to me that routine spark plug, distributor cap, distributor rotor and ignition wire maintenance prevents premature failure of the ignition control module (EZL).

The replacement module was for a 1991 300SL because the MBUSA Parts System showed modules for the 1991 300CE as "backordered".

Per a Beckmann Technologies rep these modules cannot be rebuilt because the internals are covered in epoxy which makes identification of the components impossible.

Be sure there is a coating of heat-conducting paste on the back of the replacement module you install. If not, buy some at Radio Shack and apply it to the back.
