ignition module part number query
I've got a W123 280E with chassis # WDB123033 12 113381 and engine # 110988 12 019366.
My first question is what is the correct part number of the ignition control module for my car?
The current module installed has part # 0 227 100 023, while a part number search says that I should have a module with part # 0 227 100 001.
What, if any, is the difference between the two modules?
Lastly, what is the correct part # of the ignition coil for my car?
Much thanks in advance for all the help and advice. :-)
