Used Mercedes-Benz B-Class Quarter Panel

The B-Class ran as the W245 (first generation, 2005–2011) and the W246 (second generation, 2011–2018), and these are completely different body shells, so a quarter panel from one will not fit the other. If you are sourcing a panel and are unsure which generation your car is, confirm the chassis code with the breaker using your registration before ordering.

The W246 received a facelift in 2015, and while the overall body structure remained on the same platform, pressing changes between pre- and post-facelift shells can affect quarter panel fitment – this is not something we can state with certainty. Confirm with the breaker whether the panel from their specific year matches yours by checking both registrations before agreeing a purchase.

Trim level does not affect quarter panel fitment on the B-Class – an SE, Sport, or AMG Line all share the same pressings for the same generation. You may find cosmetic differences such as side skirt attachments or moulding clips that vary between trims, so check what's included with the panel, but the structural panel itself will interchange across trim levels within the same generation.

Both a 2014 and a 2012 B-Class sit within the W246 generation (2011–2018), and the facelift did not arrive until 2015, so both of your cars are pre-facelift W246 models and the panels should be from equivalent shells. That said, always confirm with the breaker against both registrations to rule out any mid-run pressing changes before committing.

Yes – quarter panels are handed, meaning the offside (driver's side, right-hand side on a UK car) and nearside (passenger's side, left-hand side) are mirror images and will not interchange. Always specify OS or NS clearly when contacting a breaker, and double-check it against the side you need before the part is dispatched.

The B-Class has been sold exclusively as a five-door hatchback throughout the W245 and W246 generations, so body style is not a complicating variable here the way it would be on a range offering multiple body styles. Generation and facelift timing are still the key fitment factors, so confirm the donor car's year and chassis code with the breaker against your registration before purchasing.
