Mercedes-Benz EQB Sump Replacement Parts

The Mercedes-Benz EQB launched in the UK for the 2022 model year as a single generation, so a 2022 and 2023 car share the same platform and powertrain family. Because the sump follows the electric motor/drive unit code rather than the model year badge, the key thing to confirm is that both cars carry the same drive unit specification. Confirm the exact unit codes with the breaker against your registration before buying.

The EQB received a mid-life refresh, but because the generation boundaries and facelift year for the UK EQB are not widely published with enough certainty for us to state them as confirmed fact, we won't invent specific years here. What is clear is that Mercedes sometimes makes ancillary and mounting changes at a facelift point, so even within one generation a sump from one production phase may not bolt straight onto another. Name the facelift boundary to the breaker and ask them to cross-reference both registrations before you commit.

No — trim level (whether your EQB is an AMG Line, AMG Line Premium, or AMG Line Premium Plus) has no bearing on sump fitment whatsoever. The sump is determined by the drive unit fitted, not by the interior or exterior specification. You may notice cosmetic differences between donor and recipient cars when the breaker pulls the part, but these are irrelevant to whether it will fit.

The EQB 300 4MATIC and EQB 350 4MATIC are mechanically distinct variants with different power outputs and drive unit configurations, so their sumps are unlikely to interchange. The drive unit code is the single most important detail here — check your V5 or run a VIN check to get the exact unit code and supply it to the breaker. Never assume fitment based on the badge alone; always confirm with the breaker against both registrations.

Because the EQB is a fully electric vehicle, the sump relates to the drive unit rather than a combustion engine, and different output variants use different drive unit assemblies. Mixing units of different power ratings is not straightforward, and the sump from a lower or higher output variant may differ in design even if it looks similar. Give the breaker your exact drive unit code from the V5 or a VIN check and let them confirm compatibility before purchasing.

Year alone is less important than the drive unit code stamped on your car — if both vehicles share the same drive unit specification, the sump is far more likely to be compatible. That said, Mercedes can make mounting or ancillary changes during a production run without changing the model year designation, so a year gap is not an automatic green light. Supply your registration to the breaker so they can cross-reference it against the donor car and confirm the part is a match.
