Cheap BMW i3 Oil Pump

The BMW i3 is a fully electric vehicle (BEV) in its standard form, and its electric drive motor requires no engine oil and therefore has no conventional oil pump whatsoever. The range-extender variant (the i3 REx) does carry a small two-cylinder petrol engine, but this is a sealed, largely maintenance-free unit and does not use a conventional serviceable oil pump in the way a standard combustion engine does. If you think you need an oil pump for your i3, it is worth double-checking what you are actually looking for — you may need a coolant pump (for the thermal management system) or a hydraulic pump for another system entirely. We would recommend confirming with a breaker exactly which pump you need by providing your full registration number.

The i3 REx range-extender engine is a tiny 650cc two-cylinder unit derived from a motorcycle engine, and while it does have internal lubrication, it is not a part that is routinely replaced as a serviceable item in the way a conventional car engine oil pump would be. Sourcing a used oil pump for this specific unit from a UK breaker would be exceptionally difficult, as the REx engine is uncommon in the dismantler trade and parts interchangeability with other BMW motorcycles or cars is not straightforward. If you genuinely need internal engine work on an i3 REx, a specialist in BMW electric vehicles or the original supplying dealer is a more realistic route than a used-parts marketplace. Confirm with any breaker exactly what they have and whether it matches your specific REx engine before purchasing.

This is very likely the case — the BMW i3 uses an electric coolant pump (sometimes called a water pump) to manage temperatures across the battery pack, power electronics, and cabin heating system, and this is a genuine wear item that does appear in the used-parts market. Your i3's coolant pump requirements can vary between the pre-facelift i3 (2013–2017) and the updated i3 and i3s models (2017 onwards), so giving a breaker your registration or VIN will help them identify the correct unit. Do not assume a pump from an earlier i3 will directly swap into a later car without confirming with the breaker first.

For coolant and ancillary pumps, the i3s (introduced in 2017 alongside the facelift) shares much of the same thermal management architecture as the standard i3, but the i3s has a more powerful motor and different power electronics which could affect which specific pump variant is correct. Trim level in the conventional sense — whether your car is in base, Atelier, Lodge, Suite, or Loft interior specification — makes no difference whatsoever to any mechanical or electrical pump fitment. Always provide your full registration or VIN to the breaker so they can identify the exact variant rather than relying on trim name alone. Fitment is never guaranteed without checking your specific registration.

The 2017 facelift is a meaningful boundary for the BMW i3, bringing revised power electronics, a larger battery option, and the introduction of the i3s performance variant, all of which could affect ancillary pump specifications. A coolant or ancillary pump from a pre-facelift car (2013–2017) crossing into a post-facelift car (2017 onwards) should be confirmed directly with the breaker against both registrations before purchase. Named generation boundaries like this one are exactly where mid-production changes are most likely to affect parts interchangeability, so do not assume compatibility without checking.
