AC Doctor - Low Port Location W211 m272
Hate to sound like a rookie.... and believe me ... I've googled and searched this forum ... site-wide. I'd like to AC Pro charge my AC, and can't seem to located the low pressure service port. Can anyone direct me to the 2006 W211 E350 4matic M272 equipped AC Low Pressure Port? It's obviously hiding somewhere. The High pressure port is there in plain site, on driver's side, out in the open ... just behind the coolant reservoir. I'm at work now, but am prepared to dismantle the engine bay bits and pieces to find this thing when I get home. I'm hoping that a reply to this thread will prevent me from having to do that... 
Thanks, all.

Isn't the low port right beside it? On mine, there's a fat line and a skinny line right above the driver's side front wheel. Port on each one. I'd be surprised if yours is much different.

Correct. Found it. It is located driver's side, underneath the Brake Fluid reservoir black plastic cover ... up near the firewall ... Of course it was the last place I looked. Took off the airbox, front cover ... Aux Battery/Fresh Air filter box and cover ... fun stuff. High pressure one is in plain site ... not covered or nuthin'. The Low Pressure one .. is underneath the cover. AC Doctor - took half the can. Brrrrrrr .... nice and cold (quickly) now.
