Fuse C has 1.94 ma
Fuse 9 has 2.1 ma

All other fuses were 0. Between battery and negative terminal, 3.56 with all fuses in place, about 2.0 ma with fuses C & 9 out.

Please check how many milli amps you are getting at these 2 fuses with the key removed.

Fuse C (rear roof light, turnk light, rear door locking system, safery belt handover arm, seat back arrester, central locking system, door lights, reading lamps, aut. antenna)

Fuse 9 (diagnostic term 6, hazard warning system, clock, front roof light, radio, vanity mirror light, relay comfort circuitry term 86)

Intermitently, my fuel door fails to open, could that cause the drain?

The above testing was done by removing each fuse and placeing the multi meter in its place.
