Mike,

You are absolutely correct. FOM is the acronym for fixed operating mode. Thanks for the appreciation of sharing knowledge. I spend alot of time helping people people here and most of the time no one ever bothers to make one more little post to say thanks. Once their problem is solved they could care less until they have another problem. Quite frankly that is the reason many professionals don't bother to help.

I am very familiar with your car. I can even tell you how to pull codes from your MAS control unit without using a Mercedes breakout box should the need arise. Glad to help. Just ask.

Peter
