Intermittent Warning Messages

[pjs1960]

Hi,

I have a 2013 Mercedes C350, and every time I use it, within 500 meters of setting off the Control Panel goes black, and normally the ABS and EPS lights come on, as well as the message "Currently unavailable" See Owner's manual on the dials.

This happens for about 2 seconds and then they all go out and everything is fine for the rest of the journey.

I've also had the warning that the parking brake is on, but then goes off after 2 seconds.

You can sometime hear the doors trying to lock even though they already have.

The voltage regulator has been changed, but still getting this very annoying problem.

Anybody got any ideas.

How old is your battery?

A failing battery can cause all sorts of electrical issues.

Battery or batteries are 7 years old so need to get them checked.

Just change them it’s not worth the hassle imo

Hi, just to let you know, that the fault was still there after the main battery was replaced.
A week later the auxiliary battery was replaced and now everything is working as expected.
Thanks everybody for your help on this issue. ​
