Check Engine Light On when Brake Applied?

Got an odd issue which I can't seem to figure out. The CEL goes off normal when I turn on my '92 400E, but it goes on whenever you apply and hold down the brake pedal. The light then stays on.

Any thoughts or experience? Couldn't seem to come up with something similar in search mode.

You're talking about the red light on the far right, not the amber light that looks like a light bulb, right?
