We have a 98 A4 automatic that will not go into gear or move at all. When i shift to the 'drive' position there is a loud grinding noise coming from the engine bay (front right side) and it just sits there. If i return to 'netural' the sound goes away. I get the same sound if i shift to 'reverse'. There are no lights up on the dash or codes i can see out of the obd port. Any advise on what to check? I do most of my own work but i broke my foot and i'm in a cast, so all i can do is look and point at things and let my son take over from there. Any suggestions would be apprecitated.
Thanks

 

Does not sound promising if the car will not move. You say you read the OBDII and got no codes at all??
