Hi all, I’m looking at the feasibility of an n55 swap into an n20 f31 touring.
I’m in Australia so we didn’t get the 6cyl touring.🙁
I’m just in the planning stages and after coding advice. I’m looking at buying a complete damaged 435i or 335i donor car and swapping everything over. Swapping engine, trans, driveline, brakes, wiring etc isn’t an issue. What is the easiest way to go about coding to make it all work? Keep in mind I will have the full set of modules out of both the n20 f31 and the donor n55 435i/335i. I haven’t had any experience with f30 coding before so please keep it simple! I am planning on using a shop or sending the modules away to get coded so any advice would be helpful thanks.

The coding shouldnt be that complicated. Only the drivetrain modules need to be code, You can just change the typecode and code them.
