It could be either of two places, 1) in the engine compartment, passenger side close to the fire wall. 2) in the cabin, under the passenger dashboard, behind the glove box. That's where it located on a C300 and C350. My E63, it's in the engine compartment, and my C63 it's in the cabin behing the glove box.
