I have a Audi A4 B6 2.0i 2001 with multitronic gearbox and for a while i drive the car with PRND flashing in red and now when i press the acceleration in D mode the car don't move at all, the car don't go forward and backward i scanned with VCDS and this is the error on automatic transmission

17090 - Transmission Range Sensor (F125)
P0706 - 35-00 - Implausible Signal

Can someone help me please?

 

The tranny has a computer and it broke down. Flashing PRND is not as bad as PRND lit. The cost will be like $1,000.00 to fix with the new one, but you can use a used one too.
