Mercedes-Benz CLA Sill Replacement Parts

Yes, generation matters significantly for sills. The CLA ran as a first generation (C117) from 2013 to 2019, and a second generation (C118) from 2019 onwards – these are built on entirely different platforms and their sills will not interchange. Always tell the breaker which generation your car is before ordering.

Absolutely – body style is the single most important factor for sills, as the rocker panel pressing is specific to each body shape. The CLA four-door coupe (C117/C118) and the CLA Shooting Brake (X117/X118) have different sill panels that will not interchange with one another. Make sure you confirm with the breaker exactly which body style your car is when requesting a quote.

Both a 2014 and a 2016 CLA fall within the first-generation C117 (2013–2019), so you are on the same platform and body shell. That said, Mercedes did make running production changes during this generation, and whether any pressing differences exist between early and later C117 sills is something you should confirm with the breaker against your registration to be sure.

Trim level does not affect the structural sill panel itself, as the underlying pressing is the same across SE, Sport, AMG Line, and AMG variants within the same generation and body style. You may find cosmetic differences such as side skirt styling or lower trim finishers that vary by trim, so check with the breaker whether the exterior finishing pieces included with the sill match your trim level.

Engine choice makes no difference whatsoever to sill fitment – the sill pressing is shared across all engine variants within the same generation and body style. Focus instead on matching the generation (C117 or C118) and confirming the body style (coupe or Shooting Brake) with the breaker, and you can disregard what engine the donor car had.

The first-generation CLA (C117) received a facelift around 2016, but facelifts on this model were primarily focused on front and rear styling, lights, and interior updates rather than the body shell structure. Whether the sill pressing changed at the facelift point is not something that can be confirmed with certainty, so if your car is a post-2016 C117 you should check with the breaker against your registration before purchasing a pre-facelift sill.
