Alpina B4 Generations
Not sure which Alpina B4 generation you have? It's usually tied to the build year range printed on your registration document. Pick the matching one below.
Two Alpina B4s from different generations can need completely different files, even if the badge on the back looks identical. That's why we split the 1 generations we cover before getting to engines.
Frequently asked questions
Do all Alpina B4 generations support the same tuning stages?
No — available stages depend on the specific engine in that generation, not the model as a whole. Once you pick your engine, its performance page shows exactly which stages apply.
Does turnaround time differ between Alpina B4 generations?
Not meaningfully — most Alpina B4 files across generations are handled within a few hours of upload, regardless of which ECU the generation uses.
Is my Alpina B4 generation supported for safe remapping?
If it's listed in our catalogue, yes — every engine in every generation shown here has been worked before, with stage limits set to stay within that engine's mechanical margins.
How do I know which Alpina B4 generation I have?
Check your vehicle registration document for the build year, or look up the chassis code — both narrow it down to one of the generations listed here.
