Used Mercedes-Benz B-Class Intercooler

Only the turbocharged petrol and diesel variants of the B-Class have an intercooler — naturally aspirated engines do not use one. The B-Class range has included turbocharged engines across both the W245 (2005–2011) and W246 (2012–2018) generations, so intercoolers do exist on this model but only on specific engine variants. If you are unsure whether your engine is turbocharged, check your V5 or run a VIN check to confirm your engine code before searching for this part.

These are two different generations — the 2010 car is a W245 (built 2005–2011) and the 2013 car is a W246 (built 2012–2018), and the two generations use different engines, different engine bays, and different intercooler designs. Even where engine codes look similar across generations, the mountings and pipework are unlikely to be compatible. You should source an intercooler from the correct generation and, ideally, from a car sharing your exact engine code.

Yes, fuel type matters significantly because diesel and petrol turbocharged engines use differently sized and differently routed intercoolers suited to their respective intake systems. Always match the intercooler to your engine code rather than just the fuel type label, as even within diesel or petrol variants there can be differences between specific engine codes — for example OM651 diesel units versus CDI predecessors. Give your engine code to the breaker so they can confirm the correct unit.

The W246 ran from 2012 to 2018 and received a facelift in 2015, and while the core engine codes were carried across that update, ancillary components and mounting arrangements can change at facelift points. The engine code is the most reliable guide, but you should confirm with the breaker against your registration whether the pre- and post-facelift intercooler and its connections are directly interchangeable for your specific engine. Do not assume a 2012 unit will simply bolt straight onto a 2015 car without that check.

Trim level does not affect intercooler fitment — the intercooler follows the engine, not the badge or trim specification. A B200 CDI in SE trim and a B200 CDI in AMG Line trim will use the same intercooler provided the engine code is identical. Focus on matching the engine code rather than the trim name when sourcing from a breaker.

In most cases the gearbox type does not directly affect intercooler fitment, as the intercooler is part of the air intake system rather than the drivetrain. However, it is worth mentioning your gearbox type to the breaker as a cross-check, since some engine and gearbox combinations were offered in specific markets or model years and the breaker can use this to verify they are pulling the part from a closely matched donor car. The engine code remains the most important detail to supply.
