If I have offended someone with my reply, I apologize. That was not my intent. The reason I suggested having the problem professionally diagnosed was that in the past I have made the mistake of replacing parts for what I THOUGHT was the problem instead of diagnosing the situation properly. This happened recently with the ML. After reading information from several sources, I convinced myself that the Mass Air Flow Sensor was the problem. Unfortunately, after replacing the part the check engine light and the poor running condition persisted. The true culprit was a bad catalytic converter which took a professional MB technician several hours to find. I needlessly replaced the Mass Air Flow Sensor and the money I spent would have covered the diagnostic costs for the catalytic converter

Again, I am sorry if I offended. I just wanted others to hopefully learn from my mistake.

However, I would have the engine codes read first before just randomly replacing parts in the hope that it resets the check engine light. It's an expensive way to diagnose problems.

As did I Sir Alex, complete with MB diagnostic.

tabo,

$600 CA for a MAF?

A s500 or bmw 740 Maf costs $900 ca hehe.. now I know why bosch is so rich =) a maf is only a piece of wire that is heated, than cooled by the air flow to tell the engine how much air is going into it. the ob2 scanner is a very useful tool.. I have one at home and at work..
