Re: Flat battery!
Following a big service (replacing oil cooler pipes), I've suddenly got the same problem- maybe something was disturbed.
The battery is going flat when the car is parked. The battery itself seems fine, if I charge it is goes down but if I disconnect and charge it, it keeps its charge without problem. When I reconnect it, there's a bit of a spark so something seems to be drawing a current when the car's switched off. With the battery charged, everything seems ok, the car starts and runs. I can't see it being an earth problem because the car is drawing current.
I'll have to start tracing things back!
