Cheap Mercedes-Benz EQC Glow Plugs

No — the EQC is a fully electric vehicle and has never been fitted with glow plugs on any variant. Glow plugs are used to pre-heat the combustion chambers in diesel engines, and because the EQC has no internal combustion engine at all, there is nothing for them to do. If you are searching for a heating-related component, you may be thinking of the EQC's high-voltage coolant heater or PTC heater element, which warms the cabin and battery in cold weather — confirm exactly which part you need with a breaker who specialises in electric vehicles.

Almost certainly yes — the EQC is a battery-electric vehicle with two electric motors and no diesel or petrol engine, so glow plugs simply do not exist on this model. It is likely the garage looked up the wrong vehicle, or a diagnostic tool returned an incorrect parts suggestion. Ask them to clarify what the underlying fault or symptom is, as the correct part is likely something from the EQC's thermal management or high-voltage heating system instead.

Because the EQC has no combustion engine, it uses an electric PTC (positive temperature coefficient) coolant heater to warm the cabin and help condition the high-voltage battery in cold conditions. There is no equivalent to a glow plug on this vehicle whatsoever. If you need a used heating component for your EQC, search for the coolant heater or heat pump assembly and confirm the exact part reference with a breaker against your registration number.

No — trim level makes no difference here because the EQC was sold exclusively as a fully electric vehicle across every trim, including Edition 1, AMG Line, and any other variant offered in the UK. None of them have a diesel or petrol engine, so none of them have ever been fitted with glow plugs. Whatever symptom or fault has led you to search for this part, a breaker who handles EQC stock will be better placed to identify the correct electric-vehicle component you actually need.
