Used Mercedes-Benz SL Wheel Arch Liner

The SL is a two-seat roadster that has always had wheel arch liners, and fitment depends on which generation you have: R107 (1971–1989), R129 (1989–2001), R230 (2001–2012), R231 (2012–2020), and R232 (2020–present) are all distinct platforms with different bodyshell pressing, so liners from one generation will not fit another. Within a generation, liners are generally interchangeable, but mid-generation pressing changes can occasionally affect fit, so always confirm with the breaker against your exact registration before buying.

The R230 SL ran from 2001 to 2012 and received a facelift around 2008, and while the core bodyshell remained the same platform throughout, it is not certain that all arch liner pressings were unchanged across that facelift boundary. Name the generation boundary confidently — 2001–2008 pre-facelift versus 2008–2012 post-facelift — but whether a specific liner crosses that line is something you should confirm with the breaker against your registration rather than assume.

No — trim level does not affect wheel arch liner fitment on the SL, as the bodyshell pressing is identical across trim grades within the same generation. Whether your car is a standard SL, an AMG Line, or a full AMG variant such as an SL 63 or SL 55, the arch liner shape is the same; you may simply find cosmetic differences in surface finish or clips on liners from higher-spec cars. Focus on matching generation and confirm NS (nearside, passenger) or OS (offside, driver) with your breaker.

Yes — engine choice does not affect the arch liner on the Mercedes-Benz SL, as the bodyshell is shared across the petrol engine range within each generation regardless of displacement. An SL 350, SL 500, or SL 63 AMG of the same generation will all use the same liner pressing, so there is no need to match engine codes when searching for this part. Just ensure you match the correct generation and specify NS or OS to your breaker.

A 2015 SL is an R231, which ran from 2012 to 2020, so you should ask breakers specifically for an R231 arch liner. Tell the breaker your exact registration so they can verify the correct part, and always specify whether you need the nearside (NS, passenger side) or offside (OS, driver side) liner, and whether it is front or rear, as these are different parts.

The SL, SLK (R170/R171/R172), and SLC (R172 facelift) are related but distinct models built on different platforms with different bodyshell pressings, so their arch liners are not interchangeable. Although the SLC was sold as a development of the SLK, whether any specific panels cross between those variants and the SL is not something to assume — confirm with the breaker against your registration to be sure you are getting the correct part.
