I had a ****ed up general module causing a similar drain on my '89 525i, actually i had the car at the shop and the guy didn't want to pay dealer prices for the GM (it also needed a water pump) so he asked me if i wanted it and gave it to me, lasted another 6 or 7 months till it overheated and the head cracked in 3 placesOriginally Posted by BillionPa
The freakiest drain problem i ever had was a '88 735i with 38k miles. One night i was moving it into the garage and shut it off. At that moment my phone rang and i sat there for about 10 minutes. All the sudden the display on the cluster lit dimly and the gauges started bouncing up and down.
When does the drain begin? Is it directly after you shut off the car or does it take a minute? Also i am assuming it is a steady drain until the battery dies?
