Used BMW Z4 Sump

These are different generations — the E85 ran from 2002 to 2008 and the E89 from 2009 to 2016 — and they used different engine families, so a sump from the earlier car is very unlikely to fit the later one. The sump follows the engine code, not the Z4 badge, so even where engine sizes look similar across generations the block architecture changed. Confirm any cross-generation fitment with the breaker against your registration before ordering.

The E89 Z4 ran from 2009 to 2016 with a facelift introduced in 2013, but the fundamental engine block and sump architecture on each engine code did not change at that facelift point, so a sump from the same engine code should generally be compatible within the E89 generation. That said, ancillary bracketry and sensor take-offs can change mid-production, so confirm the exact engine code on your V5 or via a VIN check and verify against the breaker's part before buying. Never assume fitment from year alone.

Yes — the engine code matters above everything else, and those different displacements used different engines with different sumps, so a 2.0i sump will not fit a 3.0i and vice versa. The sDrive designation is a drivetrain label, not an engine variant, and it makes no difference to sump fitment whatsoever. Get your engine code from your V5 logbook or a VIN check and quote it to the breaker.

Trim level — SE, Sport, M Sport — does not affect sump fitment at all, because the sump is determined entirely by the engine code, not by trim or badging. The sDrive35i is effectively an engine and power variant rather than just a trim, so always check the actual engine code on your V5 rather than relying on the trim name alone. Two cars both badged M Sport with different engine codes will need different sumps.

No — diesel and petrol engines are completely different units with different blocks and sumps, and parts will not interchange between fuel types. The Z4 E89 in particular was offered with both petrol and diesel engines in the UK market, so always confirm your fuel type and engine code with the breaker. Quoting your registration or engine code directly removes any risk of being sent the wrong part.

The single most useful thing you can supply is your engine code, which you can find on your V5C logbook or by running a VIN check — it tells the breaker far more than the year or trim badge. Year and generation (E85 2002–2008, E89 2009–2016) help narrow things down, but engine code is the definitive guide for a mechanical part like a sump. Ask the breaker to cross-reference the engine code from their donor vehicle against yours before dispatch, and note that minor mounting or sensor differences can sometimes occur mid-production, so that final check with the breaker is essential.
