Exclamation Sensor Errors? Aux Battery? Software update?

Hi All
My 2016 C63s started showing these - hope to get some direction from your experiences before making a trip to the dealer (would like to avoid it if this is a DIY).
Appreciate your insights/guidance, thank you!

Could be a voltage issue, like a bad 12V battery and/or aux battery.

A great point, I have ordered the aux battery as it was the original, thanks for that!

You're welcome, hopefully that does the trick! There is also a possibility of a loose cable, check all the cables under the front passenger seat, certainly possible to accidentally knock one off.

I would suspect the Distronic Radar with a little bump, cracks, water ingress

>> Distronic Radar
If we're talking water, we're probably talking a replacement... Is this a DIY and is the unit expensive? (I'm not a mechanic...)

If is about the Long range radar then is very expensive.

But first a proper diagnosis is mandatory
