Used Mercedes-Benz EQC Catalytic Converter

No — the EQC is a fully electric vehicle with no internal combustion engine, so it has no exhaust system, no catalytic converter, and no DPF at any point in its production run. If you have received a quote or are searching for a catalytic converter for an EQC, there may have been a mistake with the registration lookup. You will not find this part because it was never fitted to any variant of this model.

Almost certainly yes. Because the EQC runs entirely on battery power, it produces no exhaust emissions and has no cat or DPF to replace. It's worth double-checking that the registration you entered hasn't been matched to a different Mercedes-Benz model — for example a GLC or GLE with a petrol or diesel engine — as those do carry catalytic converters and could cause a mismatch in an automated lookup.

Because the EQC is fully electric, there are no exhaust-related parts to source — no cat, no DPF, no lambda sensor, and no exhaust pipe. If you have an emissions-related warning or fault, it is more likely to be related to the high-voltage battery system, thermal management, or on-board diagnostics rather than any exhaust component. A Mercedes specialist or dealer would be the right starting point for diagnosing any EQC warning light.

No part from a combustion-engined Mercedes will serve as a catalytic converter on an EQC, because the EQC has no exhaust system for one to connect to. If you are asking because you own both an EQC and a GLC or GLE and need a cat for the combustion vehicle, that is a separate search — engine code, fuel type, and emissions standard (Euro 5 or Euro 6) will all matter for that fitment, and you should confirm specifics with the breaker against that vehicle's registration.
