Remaping/ Tuning box

[AceCobra1]

Hi guys,

Been reading about remaps etc.

What are your thoughts on this:

Also, do you guys know if remaping will invalidate any warranties? How well does the gearbox fair in the remaps?

Also, does teraclean & cataclean work for diesels?

Not sure if you have any manufacturers warranty left? If so then kiss goodbye to anything really engine related for under warranty.

If you have a BMW extended warranty then that will also cause problems.

If you want to "keep" some form of warranty you really only have the ACS one, but that is £2,500.

I just renewed the new AUC warranty via BMW. I got the comprehensive one so I assume it is still under warranty.

So anyone any ideas about the remap above ?
