BMW 4 series Coupé, G22 / G82 (EU)

Manual transmission fluid capacity & service interval

BMW 4 series Coupé, G22 / G82 (EU) requires manual transmission fluid with a capacity range of 1,2 to 1,6 liters. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Type	Specifications
M4 3.0 CSL Coupé PF (412 kW) (2022-2023)	Use: Normal Capacity 1,2-1,6 liter Code: ZF GS6-45BZ/DZ 6/1
M4 CSL Coupé PF (405 kW) (2022-2023)	Use: Normal Capacity 1,2-1,6 liter Code: ZF GS6-45BZ/DZ 6/1
M4 Coupé PF (353 kW) (2021- )	Use: Normal Capacity 1,2-1,6 liter Code: ZF GS6-45BZ/DZ 6/1

The manual transmission fluid capacity across all three M4 variants listed is given as a range of 1.2 to 1.6 liters rather than a single fixed value, which is typical for manual gearboxes where the accepted fill level is confirmed by fluid reaching the filler hole rather than by measuring a precise volume.
The BMW M4 Coupé PF (353 kW) carries the same 1.2–1.6 liter capacity range as the higher-output CSL variants, indicating the manual gearbox housing shares a common fluid volume specification regardless of power output differences within the M4 lineup.
Both CSL-designated variants, the 412 kW and 405 kW versions, share an identical 1.2–1.6 liter manual transmission fluid capacity, meaning the power difference between the two does not correspond to any difference in gearbox fluid volume.
All three configurations carry a normal use condition designation, meaning the listed 1.2–1.6 liter capacity applies under standard operating conditions rather than a modified interval tied to severe or track use.
The M4 CSL Coupé PF (412 kW) and M4 CSL Coupé PF (405 kW) both entered the specification from 2022, while the M4 Coupé PF (353 kW) has a starting year of 2021, making the base M4 the earliest model year represented in the manual transmission fluid data.
