Fitment questions
Does the BMW M4 have a transfer box?
No — the BMW M4 has never been fitted with a transfer box in any of its variants. The M4 is a rear-wheel-drive car (or, from the G82 generation onward, optionally all-wheel drive via the M xDrive system), but the xDrive version uses a rear-biased all-wheel-drive system with a power take-off unit rather than a traditional transfer box of the type found in four-wheel-drive off-roaders. If you have received a quote for a transfer box on an M4, the part you are most likely looking for is the power take-off unit (PTU) or the rear differential.
I have an M4 Competition xDrive — is the part I need called a transfer box?
It is a common point of confusion, but the component that distributes drive between the axles on the M4 Competition xDrive is usually referred to as a power take-off unit (PTU) or transfer case in BMW technical literature, rather than a traditional transfer box. A conventional transfer box in the off-road sense was never part of the M4's drivetrain. When searching on Findapart or asking a breaker for a quote, use the terms PTU, power take-off unit, or xDrive front-axle differential to ensure you are quoted the correct component.
Could I be looking for a differential rather than a transfer box on my BMW M4?
Yes, very likely — the M4 has never used a transfer box, so if you are chasing a drivetrain noise or a fault related to power distribution, the component at fault on a standard rear-wheel-drive M4 is the rear differential, while on an xDrive M4 it could be the PTU or the front differential. When you contact a breaker on Findapart, give them your engine code (found on your V5 or via a VIN check) and confirm whether your car is standard rear-wheel drive or xDrive, as these use entirely different drivetrain components. This will ensure you receive the correct quote for the right part.
Does the M4 CSL or M4 Competition have a different setup that includes a transfer box?
No — neither the M4 CSL nor the M4 Competition, in any generation, has ever been fitted with a conventional transfer box. The CSL is rear-wheel drive only, and while the Competition is available with M xDrive, that system uses a PTU rather than a transfer box. The part you need will depend on your specific drivetrain, so confirm your engine code and drivetrain type with any breaker you contact to make sure you are quoted the correct component.
