.06 A (60 mA) is about right, which works out to be 1.44 A per day (.06 x 24), which would take a really long time to drain a fully charged battery, in good condition.

Per MB specifications:

.015 A Central locking pump
.020 A Radio
.005 A Seat belt extenders
.010 A Anti theft system
.003 A Clock
.002 A Seat adjust memory

.055 A Total

In my clk there is no. Seat belt extender, all dashbord was off, there is no seat memory, and radio was pull off. :/ Try to pull of one by one fuses, but didint find all time the same, except then i pull off 5 fuse in boot then it went to 7.00 A then too zero then again 7.00 and so one.

Aivaras07......In reply to your initial question, as already mentioned, after you lock the car, for a MB, .060 amperes of parasitic battery drain, is about right.

FYI, the component breakdown I mentioned, were from the MB WIS Workshop manual. Note: values based on measuring after at least 5 minutes (e.g. allowing for all the convenience features to end, such as dome lights, city lights turning on to lite walking paths etc. and on how a specific model may be equipped,

Doing the math........that works out to be 1.44 A per day (.06 x 24), which would take a really long time to drain a fully charged battery, in good condition (e.g. given that our W208s are equipped with 100 ampere-hour batteries, which works out to 100 / 1.44, or the better part of 2 months).

At this time, your question has been addressed

However, in addition to not filling out the details in your user profile, which makes diagnosis / troubleshooting on the internet even more very difficult, despite typical drain #s, at this time your pulling fuses, go figure (Read, good luck with that).

Next, even as a newbie, you never explained the problem you have, leaving us to guess.

My guess, is that, you may have no start, over night

Am I correct?
