ECU Location

Where are they hiding the ECU on an 03 E500. Is it in the engine compartment? It's not on the passenger side. Anyone know?

Ask and ye shall receive. Instructions too.

Couldn't be easier. A trick is to open your hood so it's vertical rather than at an angle. Gives you a bit more room to work in there.

Nope. Yours is smack dab in the middle of your air cleaner assembly, I believe. PM user ROUPIN, he knows exactly where it is on your car.

Thanks fellas. I guess you know why I'm looking for it. Yep, it's going off for a tune Monday. Searching and reading this damn forum has me wanting to see what all the hypes about.
