Twice recently my Jan 2004, 4200 CC has had a flat battery after standing for 4-5 days. Normally the car is fine for 4-5 weeks. An ammeter shows that there is a discharge of 0.0 amps for 4 minutes, then approximately 0.5 amps for 4 minutes; 0.0amps for 4 mins then 0.5 amps - this pattern continues while being tested (over a couple of days). It makes no difference if the alarm is on or off. I have unplugged every fuse & relay in the boot, under the bonnet and in the passenger footwell and nothing makes any difference to the 4 minute pattern. Could this be the sat tracking system - fitted but not used?
Ideas please?
