So I took my E85 out for a drive a few weeks back and thought the brakes felt a bit spongey.
The other day I go in it to move it and the brake pedal goes to the floor. I also have one error light, the yellow triangle with a circle round it.
If I pump the pedal then nothing happens, it still goes to the floor.
Brake fluid is on low but still has fluid in it.
I've scanned the car with Carly as I've managed to lose my proper cable for the BMW software, and I've got the following errors:

Could anyone advise if I'm correct when I say it's likely a master cylinder rather than an ABS pump issue? I've ordered a used master cylinder off ebay but if it's something else it would be good to know?
Thanks
