Small Problem With Auris

[brainii]

At least 3-4 times in the last 2 months I have this weird issue that the car forgets what brightness setting I have set for the dashboard.

Specifically, I have set the brightness to max, for both lights on and lights off, but it forgets the lights on setting and it sets it back to the default at random.

Anyone else has this issue and is there a fix?

It first started happening when I accidentally left the fan and radio working while the car was off and it sort of drained the Battery a bit (and forgot all radio stations too), but I did manage to start it in the end and it has been 2 months since and the Battery seems fine (and radio keeps the stations too).

Try resetting the ECU - see:

I think it's Battery related. I had to replace the original Battery after 5.5 years last week. Since it didn't happen again.
