A buyer's guide to used BMW i3 dpf

No two dpfs are quite the same across different vehicles, so getting the specifics right matters when you buy used, second hand or a replacement. Answer a few quick questions below and breakers will only quote if they have the exact matching part in stock:

Fitment questions

Does a BMW i3 even have a DPF?

No — the BMW i3 is a purely electric vehicle (BEV) and has no internal combustion engine, so it does not have a diesel particulate filter or any exhaust aftertreatment system at all. If you are searching for a DPF, please double-check you have the correct vehicle, as it is possible there has been a mix-up with another BMW model in your fleet or household. No DPF exists to source for the i3.

Can I get a DPF for a BMW i3 Range Extender (Rex)?

The i3 Range Extender variant does include a small two-cylinder petrol engine, but petrol engines do not use a diesel particulate filter — DPFs are a diesel-only component. The Rex's petrol unit uses a catalytic converter rather than a DPF, so a DPF is still not the correct part for any version of the i3. If you need the exhaust aftertreatment component for the Rex, confirm the exact part required with a breaker quoting against your registration.

I've been told my BMW i3 needs a DPF replacement for its MOT — is that right?

This is almost certainly a misunderstanding, as the i3 (both full BEV and Range Extender petrol variants) does not use a DPF, and no i3 would fail an MOT on DPF grounds. It is worth going back to whoever advised this to clarify, as the fault or advisory may relate to a different component entirely. If you have the Rex variant and there is an exhaust-related issue, confirm the exact component needed with a breaker against your registration.

Does trim level affect which exhaust components a BMW i3 needs?

Trim level — whether your i3 is in standard, Range Extender, or a specification grade — does not affect exhaust component fitment, and the i3 has no DPF regardless of trim. Since the i3 is electric (or petrol-assisted in Rex form), the relevant factor for any exhaust part on the Rex would be the engine code and emissions compliance year, not the trim or interior specification. Confirm any Rex exhaust parts with a breaker quoting against your exact registration.

Would a DPF from a BMW 1 Series fit a BMW i3?

No part of this interchange is applicable — the i3 does not have a DPF, so there is no fitment question to answer here. If you are sourcing a DPF for a 1 Series, that is an entirely separate search based on the 1 Series engine code and emissions era, which you should pursue as a standalone query. The i3 and 1 Series share no exhaust aftertreatment components.
