This is exactly what it is. Just low fluid, same thing happened to me after i took it to the track. I assume I wore off a bunch of brake pad, therefore there the brake cylinders were pushed out farther making more room for fluid. So the reservoir level dropped and triggered the lights under hard acceleration. Just fill it up with a dot 4 brake fluid and it will be fine, even mixed with the motul. Unless you are really **** or see a lot of track time, then order more motul. DO NOT use dot 5, that is silicone based and will royally f your system over time. I'd keep checking the level every couple weeks to see if it keeps dropping.
