Hello! First post. Welcome to me.

I own a 1999 V70. Twice in the past month my car's clock has reset. It just forgot what time it was. At the same time, the average MPG, average MPG, and the miles readings all reset. The master odometer and trip odometer don't reset.

What could be doing this? Maybe a low battery?

thanks

 

It could very well be the speedo assembly.
There is a circuit board in the back they call a module.
