The problem is a constant 0.45A drain from the battery. When i pull out the fuse nr. 4 (20A) in the dash on the right side (The car is LHD) the drain lowers to 0.08A which is fine.
This fuse goes to the basic module underneat the dash on the right side.
I have checked and disconnected the following:
- All 5 doors.
- Both ECU in the engine room
- Windscreen wiper engie
- Checked fuse under passanger seat on the right side. (in the floor).
Ive also changed the basic module and coded it with Autologic, and then a strange thing happend. The drain where then about 0.54A constant and when i took out the fuse nr.4 it just lowers to 0.19A.
Ive changed back to the old basic module and then the problem is as it first was.
The only problem with this car is this constant drain...
