s70 awd angle gear & rear drive removed
 

I removed the angle gear and rear drive shaft 1yr ago, front wheel drive works fine; except in the snow. The computer still thinks its awd and the front wheels slip. Is it possible to trick the computer or disable sensors?

Isn't this normal?

Normal yes for AWD; however, without the AWD the the transmission is sending power to the rear wheels and there is no angle gear or drive shaft to the rear wheels. therefore no power to the front wheels
