Hi All,
I have a 2002 Laguna 1.9 DCI that has a battery discharge problem. Below are the diagnostics I have performed so far.
8-month-old battery, drop test OK
Charging system tested OK
The car is driven 100 miles daily and starts the next day. However, when left for 2 or 3 days the battery is discharged. I am not leaving any electrical item on and there are no third party devices. I have checked interior lights etc.
I have checked the current drain by connecting a digital multi meter in series with the negative terminal. This test appeared OK with a 30 mA reading after about 30 seconds.
I suspected an internal fault on the battery even though it is new and tested. To eliminate it, I took it out of the car and left for 2 or 3 days. It's reading after this period of disconnection was 12.48V - OK.
There appears to be an intermittent problem with an electrical device "waking up" and not shutting down. Could anyone give advice on how to diagnose/solve the problem?
Any help greatly appreciated as I cannot afford to trade the vehicle.
Kind regards
