Used Mercedes-Benz CLS Bonnet Strut

The CLS bonnet is supported by a solid prop rod rather than gas struts — there are no bonnet struts on this model at all. If your bonnet isn't staying up, the issue is likely a bent, missing or broken prop rod or its retaining clip. Search for a CLS bonnet prop rod instead, or confirm with the breaker exactly which support mechanism your car uses against your registration.

A bonnet strut is a gas-filled support strut that holds a bonnet open automatically without needing a prop rod. The CLS uses a traditional manual prop rod design across all generations, so no gas bonnet strut was ever fitted to this model as standard. You'll want to search for a bonnet prop rod or bonnet stay rod to find the correct part for your car.

The CLS doesn't use a gas strut to hold the bonnet open, so a strut isn't what you need. The bonnet is held up by a removable prop rod that locates into a hole in the bonnet, and if the rod is lost, bent or the locating clip is broken, the bonnet won't stay propped. Contact a breaker and ask specifically for a CLS bonnet prop rod, quoting your registration so they can confirm the correct generation part.

The CLS has been produced across two main generations — the W219 (2004–2010) and the W218 (2011–2018, with a facelift around 2014) — and these are distinct platforms with different bonnet designs. A prop rod from one generation is unlikely to be a straight swap to the other due to differences in bonnet geometry and prop hole placement. Confirm the generation against your registration with the breaker before buying.

No — trim level does not affect which bonnet prop rod you need, as the bonnet and its support mechanism are shared across all trim grades within a generation. Whether your CLS is an AMG Line, Sport or standard specification, the prop rod fitment is determined by generation and facelift period, not trim. Just make sure the breaker is supplying a rod from the same generation as your car.
