The last couple of weeks my 2007 S550 with 60k miles. The display has started to display the attached error messages in random sequence. The car is running great it happens 2 to 3 times a week. The check engine light comes and goes more often no codes show up when I plug in an OBD. I swapped out the gas cap hoping that would help it did not. The gas tank is always full when the display goes crazy the full gage falls to empty. The tachometer and speedometer continue to work.

I am not sure I am going to keep the car much past 65k. I bought it last year with 40k for a song and will most likely replace it with a 2012 or 2013 in the next couple of months. Any Idea what I am dealing with here?

Battery undervolt can cause a bunch of weird meaningless messages to pop up. Is it possible the battery is weak?

thanks Mike I will check the battery.

He's referring to the large accessory battery located behind your back seat.

yes, either weak battery or one of your grounds have disappeared.

however, i would first have the car rear with star/ das. undervoltage errors very often are logged and will point to a weak battery. if not, other errors might point at potential culprits.
