Sooty exhaust smoke, sluggish throttle response or an intake drawing in unfiltered air are classic signs that the air filter and its mounting should be checked on a 740 with the D24 diesel. A clogged filter restricts airflow, while worn rubber bushings and loose clamps in the air filter housing can let unfiltered air slip past – something a diesel engine is especially sensitive to.

This category includes air filter elements, air filter housings and the small parts that keep the system in place: rubber bushings (including M8), buffers, clamps, washers and screws. You'll also find thermostat-related parts that sit close to the air path during the same service job.
The D24 is its own engine variant in the 700 series, so the filter and housing differ from the gas variants B200/B230 and B280. Therefore, check that the element and mounting match your specific D24 before ordering – the bushing dimensions and the housing's mounting points are common differences to verify.
