Hi guys....after some advice.
I have just acquired an E46 2001 325 Touring.....Seems to have a battery drain issue. I've owned it for less than 3 months, and immediately this problem presented itself. Am talking to the dealer with regards to the warranty at present.
Battery fully drains itself from a fully charged battery to completely flat within a 3 day period. That said....sometimes it doesn't.
I replaced the battery just assuming that the old one was knocking on a bit. No joy. BMW looked at the car and told me that it was the ballast (sic?) resistor causing the drain and replaced this as well. However...a week later I am stuck with a fully flat batteried 325 on my drive again.
Am so fed up...anyone experienced anything similar or have experience of similar issue and remedy?
