Hi all, I have this auxillery battery malfunction error in my dash at the moment. I had it 2 times before, but it went away again(both times it lasted 2 days and then it was gone again) this time its gone on day 3 - and I have seen errors in the navigation(drives where there is no roads) reading speedsigns wrong and left side climate control button was not working(not able to turn the degrees up or down) speedsigns works again, so does climate control but navigation is still a mess. Is it time to change this aux. battery?

Forgot to mention that the 2 x 2 days has been in a period of 2 months... like with 3 weeks apart atleast

I'd say it's a good place to start. it's not a battery, but a supercapacitor bank and the caps leak. You might want to scan for codes first, but the aux battery is a cheap thing to try since that's what it's been diagnosing.
