HELP! HELP! HELP!

Can anyone help with the fault codes in the hidden menu, I have 2:
E12C01
E12C03

I also have a problem when selecting 1st (D) it sometimes jerks violently, and it sometime jerks when it gears down into 1st when coming to a stop.

There is no pattern as to when this will happen I.e. hot, cold or been stood for a while, I just know when its going to happen as when put into drive it does nothing for a couple seconds then jerks rather than feeling the drive engage.

Any help is welcome, if anymore info is required let me know.

No doesn't sound like what trouble i'm having,

Also mine is the N47 engine with the 8 speed auto box.

Idle is rough until it gets to optimal temp, and it sometime throws its self in 1st gear (either from N/P or gearing down)

Tried EGR cleaner and tons of fuel additives.
