Hi there
I'm new to this forum, and I have a problem (Audi A3 8P 2010).
It has a new battery, just six months old, and over the past few weeks it's been running right down while the car is parked up. It holds its charge when the positive terminal is disconnected, so I'm looking for a fault in the car.
With the battery fully charged, and the ignition off, I've checked for current across whatever fuses in the engine compartment that I can access while the fuse is in place (all the smaller fuses up to 20-30A - the thinking (possibly false?) that there should be no current flowing while the car is switched off. I'm getting a current across the 5A fuse at position F6, and a bit of a search on Google brings me to the diagram corresponding to the layour of my fuse box. F6 is the Instrumentation Control Module.
My initial questions are: first, would a current across this fuse indicate a fault in the Instrumentation Control Module; and second, if so, then what - is it possible to buy a new module and just plug it in (wherever it's located, which I don't know), and would that be very expensive or is there another option? I live in a pretty remote place, so that getting the car to an Audi service place and leaving it there would be difficult for me.
I'm by no means a car expert, as you can probably tell, but I'm hoping someone might be able to advise. The next step, I'm thinking, might be to remove that fuse and see whether the battery still discharges when the car is sitting and not switched on; the battery won't be fully charged till tomorrow, so in the meantime I'm trying to explore whether I'm on the right track or not. I should add that as far as I know the various instrument functions are ok, but again I can't confirm that till the battery is back connected up.
Thanks in advance
Heather
