1990 Mercedes-Benz 300SE Q&A
1990 Mercedes-Benz 300SE Question: why did my odometer and gas guage stop working?
my car did the same. I had to replace a fuse that had blown. - merced300
Check the coffin box, located at right side engine near passenger. It has a hard plastic cover and attached by 4 lug screws. Once you open, you will see several computer modules. The one at the far back should have fuses inserted into it. They should all be 10amp. Check them all and I will bet that one is bad. It controls your speed censor and ABS. It has worked for numerous people. Thanks - brownrice
