2010 Mercedes Benz E350. Am getting system malfunctions showing up on the instrument panel, but they seem to be intermittent.

What is your question?

The "auxiliary battery malfunction" appeared, so the aux battery was replaced. Still reappears every couple of days. Also, had the "cruise control inoperable" appear, but the next day it was working. Another day the automatic lights feature was inoperable, Next day it was fine. Do I need a new computer or an update? Should also tell you that last January there was some sort of computer failure that would not allow the vehicle to shift into gear from park, with a red alert "do not shift gears, service required". Repaired: "M.E. was taking down can bus. Replaced M.E. and profgrammed."

What makes this problem better or worse?
