Hello
I own a 02 audi A4 3.0 quattro,when i tried to start the engine i noticed "PRNDS" flashing on my dashboard and it feels a beat when trying to move from P to reverse or drive and the car runs hardly,restarting the engine solved the problem
I scan the vehicle with vAG and this what it cames from:

18232 -pressure control valve 3 (N217)
* * * * * * P1824-003- open or short to ground- intermittent
* * * * * * Freeze frame:
* * * * * * RPM :64/min
* * * * * * RPM:0/min
* * * * * * RPM:0/min
* * * * * * No units :0.0
* * * * * * Torque :60NM
* * * * * * Temperature 28.0 degre

18227- Pressure control valve 2 (N 216)
* * * * * *Open or short to ground -intermittent

Any idea
Thnk u in advance
