Hi I have discovered why the gearbox isn't performing as it should. Recently it's not wanted to set off(from 1st gear)and when it does this the 1 is flashing next to the A. Also a bit sluggish on acceleration and when braking shudders a bit like when braking and not putting the clutch in (on a fully manual gearbox)Got someone to plug in a scanner and it's come up with codes U1405,U1404,U140 and ,P0562 all starting with F -can malfunction ABS/VSA modulation control unit. Would this be an easy/cheap fix? Thanks
