WHERE is the MAF and HOW do you remove it on M119/400E?
Step two, remove airbox.
Step three, look down.
Big round thing on top of throttle actuator, screen on top. Last I checked, new ones were pretty expensive. $300 or so.
You can also connect the maf directly to the SDS system and it will tell you if the voltage is within spec, thats how the dealer determines if the maf needs to be replaced.
