Brewtoo,

I'm standing by my statement, but MB does have some slop over model changes which is why you must use the last 6 digits of the chassis # when ordering parts. You can't just go by year model. On the one hand you are lucky if your fuel pump relay quits, because you will have to replace the MAS unit and not the main computer. On the other hand if you get codes stored in the MAS unit, you will need a 35 pin breakout box to reset the codes. Codes stay stored in a MAS unit even when it is removed unlike the main computer which can be reset by disconnecting the battery.:p
