(Power)steering failure

[dangerdred]

I have a multimeter yes. I went out now to test the voltage on the battery and it's at 12.2V. I got into the car and turned on the ignition and now I see two bars on the MMI!. When I checked the fluid earlier I started the engine for no more than 30 seconds after I saw that the system did indeed have fluid and to check if I still had my PS issue (which I did). If the running engine charged the battery from one to two segments in that short time and now a couple of hours later the two segments (12.2V) are still in the battery then the battery drain must indeed be very slow.
The engine still turns and starts no problem with the battery at one bar on the MMI. but I'm thinking I can't have had this drain all along or my keyless would have stopped working long before now, so I'm al a loss where all of a sudden this battery drain has come from.

I'll need to charge up the battery again before a scan or I'll be getting errors all over the place.
