Hello,
Where is the ambient air temperature sensor located? It is a ML350 2006 SUV, and the OBD II code is P0073.
Thanks!

If you mean ambient Air Temp Sensor for the Climate Control System,

usually located at front of the vehicle (attached to the bumper),,

Yes, this is the right part that I am looking for. Is it easy to remove the front bumper? Are you aware of any instructions/diagram for the bumper removal?
Thanks!

Don't have specifically instruction for "W164",

but mostly, no need to remove bumper,

as i think; this sensor attached to the bumper grill, you can pull it out easily to replace it..
