DIY coding and updating ?

[Paulpen]

Hi guys - sorry if this has all been covered but im pretty new to BMWs and certainly new to this part of it all !

Ive got a new twin axle air module in the post to me and im aware that as its new im going to need it coded / matched / set to my car (im not sure on the right terminology).

I also need my autogearbox / mechatronic ecu updated due to the 1-2 tranny slam having found out about it on here.

Now are these things I can do myself or am I best taking it to BMW for both of these things ?

Ive got the Romanian package on its way to me (ISTA/D 3.53, TIS, SSS v32, INPA Ediabas 5.0.6, NCSExpert 4.0.1, NavCoder demo).

Will I have the ability to do both things with that and is it safe for me to do so being a total novice ?
