Red face Battery drain S55 AMG 2001

Hi!

My car is draining aprox 1,8A constantly and ive been clamping alot of cables to come closer to the fault. If you see my attached pic there are two cables going in a plastic "tunnel" over the climahousing. I know one is for the ignitionswitch and i got no amps on this one. So do somebody know where the other one goes??

I pulled out the radio/nav and climacontrol, glovebox and clamped everything.. Is it going to the front right sam/fuse box?

Thanks in advance!

1.8A is huge - lots of stuff is still awake. You need to close and lock all doors and wait half an hour before you ever see quiescent drain.

Of cause its a huge drain and yes this is when the car is in sleep with locked doors etc. I work daily as faultfinder on vag i know what im doing. Just not familiar with mb construction yet and where that cable goes.

Cheers
