Used BMW Z4 Bonnet Strut

Yes, the BMW Z4 uses gas-filled bonnet struts (sometimes called bonnet stays or gas struts) to hold the bonnet open – this is standard across all generations of the Z4. Unlike some cars that use a fixed rod, the Z4 relies on these pressurised struts, so if yours has collapsed or failed, a replacement strut is the correct part to look for. You'll typically find one strut on each side of the bonnet.

The first-generation Z4 covers the E85 roadster and E86 coupé, produced from 2003 to 2008, with a facelift introduced in 2006 that updated the front-end styling including the bonnet area. Struts from within the same pre-facelift (2003–2006) or post-facelift (2006–2008) period are your safest starting point, but whether a pre-facelift strut crosses over to a post-facelift car is something you should confirm with the breaker against your registration, as bonnet geometry can shift at a facelift. The E85 and E86 share the same platform and front end, so roadster vs coupé is not expected to affect bonnet strut fitment.

Engine choice does not affect bonnet strut fitment on the Z4 – the bonnet and its supporting hardware are shared across the engine range within a generation. Whether your car has a four-cylinder or six-cylinder engine, the strut should be the same part, so don't let a seller's engine specification put you off. Confirm the generation and facelift period match, and you can disregard the engine entirely.

Trim and engine variants such as sDrive18i, sDrive23i, sDrive35i, or the high-performance sDrive35is all share the same bonnet and strut fitment on the E89 platform. The bonnet strut is a structural part, not a cosmetic one, so trim level is irrelevant here. The E89 ran from 2009 through to 2016 with a light update around 2013, so if you're buying across that boundary, confirm with the breaker using your registration to be sure.

No – the E85 (2003–2008) and E89 (2009–2016) are entirely different platforms with different bonnets, so their struts are not interchangeable. Always make sure the part you're buying is from the same generation as your car. Quote your registration to the breaker so they can verify the correct part from a matching donor vehicle.

Both years fall within the E89 generation (2009–2016), so they share the same basic platform and bonnet structure. There was a minor refresh on the E89 around 2013, and while the bonnet strut is unlikely to have changed at that point, it's worth confirming with the breaker against your exact registration before buying, as subtle production changes can catch buyers out. A good breaker will be able to cross-reference the part number to confirm a match.
