what is causing 0,55 amp draw ? - all fuses are out

Dear Mercedes forum.

I decided that i want to find my battery issue.
i hooked it up and it shows 0,45-0,55 amp draw after the 20 min cool down.

i pulled all the fuses one by one and checked, in all 4 fuseboxes. and most of the modules.
today i took apart all can bus.
i checked for all lamps.

any idea what can cuase this.

how can i disconnect the gps and telaid ? i took off the power and can bus cable in the trunk. should i do more.

i have a red optima ah50 rc 100 - cca800 - it can hold a couple of days.!. its very annoying. .... 2,5 days- 3 days and still start it - depending on how much i recharge it from the last trip

im almost giving up - im dying in the south florida sun and heat !. considering to install a dead switch or prioty start.

sometimes the seat memory system will cause this. disconnect the fuses for your seats and see what happens.

There is also a fuse for the cd changer and amp in the trunk where the cd changer is located. Don't forget the fuses under the rear passenger seat. Some 215's also have a few fuses on the side of the glove box behind the plastic cover.

Priority Start or rather a Battery Brain would be my choice
. The battery brain has a model with remote control they also act as a security system
To reduce your insurance rates
