Hi, new to mercedes, in the process of fixing bits and bobs on my new toy, w124 260e, 1991 year. The car has a bad battery drain, measured at 0.35 amps. If i remove fuse 9, the drain halves and if i remove fuse C the drain drops to an acceptable 0.03 amps. I have disconnected central lock pump, electric aerial, interior light / sunroof switch, boot light all to no avail. One point to note is that the drain can be intermittant, ie when meter connected not always there. All interior lights off when drain is 0.35 amps. Any ideas chaps? Its doing my head in!
Battery drain!

Try leaving a front window open and operating a window with the doors shut and the ign off. if it still works, check door switches and then the comfort circuit diode. might have failed.
