My car hasn't been performing very well in snow even though the awd seems to be working. When driving in snowy roads uphill i have to use much power to get it going and the feeling is not great, even though its awd i have a feeling like driving 2wheel driving. It doesnt feel secure in turns so i'd say something isnt right. In the same conditions going uphill old quattro had no problems at all.. Even stopping on a hill and starting again when i couldnt do that. And the quattro didnt ride on very good tires. I have a set of cooper tires with 8mm thread left and 1 year old. So my question is there a possibility that awd just isnt performing right? Feels like its working just 60 or 70%. My guess is awd either works or doesnt work but i dont know. When tested on ice all tires are spinning so my guess was that awd is working. Any ideas??
