I'm in the middle of debugging my E39 (same M54 engine you have) parasitic battery drain so the OP might benefit from the extensive writeup I did over here to debug and narrow it down with respect to the Final Stage Resistor (aka Final Stage Unit):

Please read the suggested threads and add value, either by pictures or by descriptions, so the next person stands on your shoulders.
