random battery leakage
Hi. I have a 2004 E53 X5 owned since new. Throughout it's life it has randomly flattened the battery for no apparent reason. BMW specialists could not offer any solution however recently it was suggested I should replace a resistor associated with the cabin fan assembly and this was done without providing a solution. More recently the problem has increased so that the vehicle is virtually unusable. As soon as the car is taken out of sleep mode it will suddenly cause a battery leakage of around 30 amps which very quickly results in the battery going flat with a voltage of 8 or less volts. the vehicle has now been with a specialist auto electrician for 3 weeks and he cannot identify the cause of the leakage. the battery is not considered to be faulty and I actually replaced one around 2 years ago in the hope this would solve the problem but it did not and the old battery was checked over some months and proved to be perfectly OK. Unless I can have this problem fixed the vehicle is only good for wrecking. Can anyone help?
