Parasitic Battery Drain on 2011 V60

[L1OFF]

I've been having issues with my V60 battery draining in a couple of days, replaced the battery as it was a cheapy from ECP (look fairly old) and was on the car when I bought it a couple of years ago. The car is not used much as its the family hack and we are both working from home, new battery checked after a couple of days and its down to 11.5V (0.89A draw when locked!).
As I'm not too busy today, I spent some time browsing YouTube for clever ways of finding the issue rather than the old fashioned way of multimeter in series with the battery and pull the fuses one by one. There was one that had checking the volt drop across the fuse and checking on a chart how many milliamps that corresponded to (tried that, didn't work). Plan B isolate the 4 fuse boxes in turn to find which one is causing the issue. Turned out to be fuse block B (under dash), pulled 4 fuses at a time and narrowed to central locking \ fuel filler cap. Looking like the fuel filler cap solenoid. Disconnected and now all good. Took 1 hr to do.

Just bear in mind that if your battery got that low a few times it could well be seriously weakened by now.

Yes that was a concern. Will keep an eye on it for a few weeks.

There's a bit more to this, battery down to 11.5V again, check with the multimeter and still drawing current when all off. Went back through the routine of fuse pulling and fuse 7 (Box A) cleared the fault. Turned out to be the Steering Wheel Control Module, (EBay £15 for a SH one). Bugger getting the air bag off but done now.
