Mercedes-Benz CLA Exhaust Manifold Replacement Parts

Most CLA engines are turbocharged, and on these variants the exhaust manifold is typically integrated into the turbocharger housing or the cylinder head itself rather than being a separate bolt-on component — so a standalone 'exhaust manifold' as a separate part is not commonly found on these engines. What you may actually be looking for is a turbo inlet/outlet pipe, a downpipe, or a combined turbo-manifold assembly. Tell the breaker your exact engine code (for example M270, M133, OM651, or OM607) and describe the specific section you need, so they can identify the correct component. If your car is showing exhaust-related fault codes or symptoms, a breaker can also advise whether the issue is more likely the turbocharger assembly itself.

The C117 CLA ran from 2013 through to 2019, with a facelift in 2016, and the 2014 car sits in the pre-facelift phase while a 2018 car is post-facelift; both generations share the OM651 diesel engine family, but emissions calibration and associated pipework can differ across that facelift boundary. Because diesel exhaust components are closely tied to the emissions era and DPF configuration, you should not assume a downpipe or turbo outlet from a post-facelift 2018 car will be a straight swap onto your 2014 car. Confirm the engine code, Euro emissions standard, and DPF arrangement with the breaker against your registration before purchasing. Fitting the wrong emissions-era pipework could also cause MOT issues.

Trim level does not affect the exhaust manifold or downpipe fitment on the CLA — what matters is the engine code and the emissions era, not whether your car is badged SE, Sport, or AMG Line. The exception worth noting is the AMG CLA 45, which uses a completely different high-performance engine (the M133) and its own turbo-manifold assembly, so parts from a CLA 45 are not interchangeable with standard CLA engines. When searching with a breaker, focus on matching the engine code and fuel type rather than trim name. You may find cosmetic differences in rear exhaust tips between trims, but those are aesthetic and unrelated to the manifold or downpipe.

The second-generation CLA (X118) launched in 2019 and is a completely different platform to the original C117 (2013–2019), so exhaust and turbo-related components are not interchangeable between the two generations. Even where engine families appear similar on paper, the packaging, sensor positions, and emissions hardware differ between the C117 and X118. Always confirm which generation the donor car belongs to by checking the chassis code or registration with the breaker. Do not rely on year alone, as late C117 and early X118 production years overlap in the used-parts market.

The engine code is the single most important piece of information for matching exhaust components on the CLA — common petrol units include the M270 (used in the CLA 180 and CLA 200) and M133 (CLA 45 AMG), while diesel variants typically use the OM651 (CLA 220 CDI/d) or OM607 (CLA 180 CDI/d). You can find the engine code on a sticker inside the engine bay, on the V5C, or by entering your registration into a data check. Pass both the engine code and your registration to the breaker, as they can then verify the correct emissions standard and ensure any DPF or catalytic converter arrangement matches — specifics around those components should always be confirmed with the breaker directly. Getting the engine code right upfront saves time and avoids buying a part from the wrong emissions era.
