Cheap BMW 1 Series Oil Cooler

Oil coolers are fitted to many BMW 1 Series engines but not universally across the range — in general, the higher-output petrol and diesel engines (such as the six-cylinder units and the more powerful four-cylinder turbos) are more likely to carry an oil cooler, while some lower-output variants may not have one as standard. The definitive way to know whether your specific car has one is to check against your registration or engine code, which your breaker can run before quoting. If you are unsure whether your car has one at all, it is worth confirming this with the breaker before ordering.

The E87 and F20 are entirely different generations with different engine families, mounting arrangements, and cooling system layouts, so an oil cooler from an E87 is very unlikely to be a direct fit on an F20. Engine code is the most important detail here — even if two cars share a similar badge (for example, both badged 118d), the underlying engine and ancillaries changed significantly between generations. Always quote your engine code and registration to the breaker so they can match the correct unit.

The F20 generation ran from 2011 to 2019, with a facelift introduced in 2015, so a 2014 car is pre-facelift. Whether the facelift brought changes to the oil cooler or its mounting depends on the specific engine code, and this is something to confirm with the breaker against your registration rather than assume. Your engine code — found on your V5 or via a VIN check — is the single most useful detail to supply when getting a quote.

Trim level — SE, Sport, M Sport — does not affect oil cooler fitment because this is a mechanical part that follows the engine, not the badge or interior specification. The exception worth noting is the M135i and M140i, which use higher-output engines (the N55 and B58 respectively) that are genuinely different from the rest of the F20 range and will need an oil cooler specific to those engines. Always lead with your engine code rather than your trim name when speaking to a breaker.

No — diesel and petrol engines are mechanically distinct and their oil coolers are not interchangeable, even within the same generation and year. The engine code makes the fuel type clear and is the most reliable way to ensure you are quoted the correct part. Always confirm your engine code with the breaker rather than relying on the fuel type alone.

Body style has no bearing on oil cooler fitment; the part is determined entirely by the engine code and drivetrain, which are identical regardless of whether your car is a three-door or five-door. You can safely buy from either body style as long as the engine codes match, but always confirm the full specification with your breaker before purchasing a used part.
