Hello! have a great condition (75k mikes only, very well looked after and i had it for 8 years) E53 and it recently developed what appears to be an intermittent parazitic current draw...
yes, car only used 1-2 times/week so not much use but problems only started in the last few months.
- had a new battery installed as thought old one was a suspect.. did not resolve..
- used multimeter to measure draw between battery and vehicle- after car goes to sleep - dropps to 0.23A OR sometimes to 0.17A.... i believe it should be 0.04A max
- i pulled ALL fuses (glove + rear compartment) trying to find the suspect circuit but makes no real difference to Amps reading... by the way - i pulled the fuses - did not re-installed them not to "wake" up the car... i disconnected DVD nav unit, CD changer.. no impact....
- no after market gadgets installed.... as mentioned - i had the car for 8 years and never had issues like this in the past....
about to install remotly controlled battery switch to disconnect the battery when car not in use for a few days but i would still like to fix the problem!
any thoughts / suggestions please..?
