I just came back from holidays with mit Edge, and on the Autobahn these two warning lights came up sporadically. Sometimes it came up on bumps, then it goes out on the next bump, then it came up when I went down the hill or when I accelerated.... really very.
Sometimes it was on for 10 minutes, then nothing was lighting up for 2 hours...
What could be the problem? Brake Fluid is full.
I have noticed one tire had less pressure, but nothing changed after I filled it up again.
