Coding digital speedo on F30 with Bimmercode - tutorial

B47 all the way. The N47 timing chain issue is a deal breaker. Spend the extra money and get the B47. Your wallet will thank you later.

This was the first coding I did on my F30 and its so worth it. The digital speedo is much easier to read at a glance than the analog one. One tip: after coding, you might need to do a battery reset (disconnect for 5 minutes) for the instrument cluster to fully update. Some people report the speedo not showing until after a restart.
