Second Hand Mercedes-Benz EQB Throttle Body

No — the EQB is a fully electric vehicle and has no internal combustion engine, so it has no throttle body at all. Throttle bodies regulate airflow into petrol or diesel engines, and because the EQB uses electric motors only, that component simply does not exist on any variant of this model. If your EQB has a drivability or power-delivery fault, the issue is more likely related to the accelerator pedal position sensor, inverter, or motor control unit — a Mercedes specialist or EV-experienced breaker would be the right starting point.

Almost certainly yes — no variant of the EQB, whether the 250, 300, or 350 4MATIC, uses a throttle body because all versions are fully battery-electric. A seller listing a throttle body for an EQB has likely misidentified the part or applied the wrong vehicle reference. It's worth going back to them with your registration or VIN to clarify what part they are actually supplying.

Because the EQB never had a throttle body fitted, there is no such part to cross-reference to another vehicle. If you need a throttle body for a different Mercedes model — such as an A-Class, C-Class, or GLC with a petrol engine — the correct approach is to search by that vehicle's engine code, which is the single most important detail for throttle body fitment across Mercedes petrol variants.

On an EQB, loss of power or unusual acceleration behaviour is typically linked to the accelerator pedal sensor, high-voltage battery management, inverter, or electric motor rather than anything resembling a throttle body. A diagnostic scan with Mercedes-compatible software (such as Xentry) will point you toward the correct component. Describe the fault to a breaker or EV specialist with your registration to hand so they can identify the right used part.
