I don't know what year the fuse fix was added, or if it ever was before the W123 ended production. My 1984 300D still used the 25A stock fuse and it was always melting/blowing and causing problems. I added an external GM-style 30A fuse located in that little relay box on the driver's fender, which solved the problem permanently. This was cheaper than using new OE components (I had the GM stuff floating around in my Pot O' Gold), although if you can find them used that would be a more 'correct' solution. Even the early 124's had this problem, it was corrected in the middle of the 1987 production run... all 124's after 1987 have an external 30A flat fuse.
