BMW 418d F32/F36 N47 / B47
The BMW 418d belongs to the F32/F33/F36 4 Series generation, built approximately 2014–2020. Production moved from the N47 to the B47 engine family at approximately 2015, so the exact engine must be confirmed on each vehicle. Covered body styles are Coupé and Gran Coupé. Depending on the variant, it was offered with rear-wheel drive or xDrive all-wheel drive, paired with a manual gearbox or an automatic gearbox. Engine management is by a BMW DDE; identify the exact ECU hardware and software from the vehicle before ordering a file.
