In my 2006 octavia 2 automatic it starts fine.bt within few yard it start flashing prnds n gears dont shift.earlier it had problem in manifold flap motor in which egr value is not working.i didnt get that repiared.is it a new problem or flapmotor problem?

Get the codes read via vcds. This sounds like its a new problem to me.

Can this be a call for new clutch plates??

Could be related to low oil level.
