BMW Chassis Codes (1984–2026)

What is a BMW chassis code? BMW names every generation and body style with a chassis code : a letter and a number such as E90 , F30 or G20 . E-codes ran from the 1960s to about 2013, F-codes from 2010 and G-codes from 2015, and the newest cars use U-codes (X1 U11). M cars usually carry their own code, so the M3 is an F80 or G80 while the 3 Series is an F30 or G20. The code tells a tuner which ECU and calibration a car has.

Confirm against your VIN. How to find your BMW chassis code Model and year: find the model above and match the year. VIN: AMR can confirm the chassis and engine from your 17-digit VIN. Engine too: one chassis can carry different engines (a G20 330i is a 2.0T four, an M340i a 3.0T six), and the tune follows the engine. Looking to tune your BMW?
