Newbie from Poland - just bought my first BMW

Welcome! The F30 318i is a solid first BMW. Before thinking about tuning, make sure all the maintenance is up to date - oil, filters, brake fluid, coolant. The B38 3-cylinder engine in the 318i is actually quite peppy for what it is. Bimmercode is a great starting point for coding some cool features without any risk.

I was in the same boat a year ago with my first BMW. My advice: join this forum, read a lot before doing anything, and start with small mods. Coding with Bimmercode is addictive and free (well, the app costs 30 EUR but thats it). Welcome aboard!
