About part number MV4B-S278B51-AC

A rear arch liner, also known as a splash guard, forms a protective barrier inside the wheel arch on the left-hand side of the vehicle. Part of the exterior body protection system, it sits above and behind the road wheel to shield the inner wing and chassis components from road grit, water, mud and stones. When it is intact and properly secured, the driver will notice reduced road noise from the rear tyres and less debris rattling against the underbody.

To confirm this part is correct for your vehicle, you must check the part number directly. The manufacturer reference for this item is MV4B-S278B51-AC. On an arch liner, this number is usually stamped or moulded directly into the plastic surface on the inner side, which faces towards the vehicle body. Matching this exact part number is the only way to guarantee a correct fit, as shapes and mounting points vary across different vehicle trim levels and body styles.

When fitting a replacement arch liner, a person will commonly need new plastic fixings, trim clips and screws, as the original fasteners often break, rust or go missing during removal. These liners are usually replaced after sustaining damage from road debris, wheel impact or kerb strikes, or when they become loose and rub against the tyre.

  • Part type: Splash Guards & Mud Flaps.
  • Specification: country of origin Germany.

About this kind of part: wheel arch liners

A wheel arch liner is the moulded plastic or felted shell inside a wheel arch that keeps water, salt and stones off the inner wing, the suspension and the wiring. It is hidden and it is not structural, but it is the part that decides whether the metal behind it rusts, so a missing or torn liner is a slow problem rather than a cosmetic one. Mudflaps, undertrays and the air ducts that feed the brakes are the same kind of part doing the same job elsewhere under the car.

Why people replace one

  • The liner has torn away from its clips, usually after a wheel has picked it up at speed, and it now rubs the tyre.
  • Road debris or a kerb has split the liner along an edge.
  • The clips and screws have rusted away or pulled through, so the liner hangs down and catches.
  • The liner was removed for a repair and never refitted, which leaves the inner wing exposed.
  • A felted liner has become waterlogged and heavy and has pulled itself off its fixings.

Fitting it

  • The wheel normally has to come off, and the car must be supported properly on axle stands rather than a jack alone.
  • A liner is held by a mixture of plastic screws, clips and expanding rivets around its edge, and most of them break on removal, so a set of fixings is worth having before starting.
  • Fit the fixings loosely around the whole edge first and tighten them afterwards, otherwise the last few holes will not line up.
  • With the liner out, it is worth looking at the metal behind it. A liner that has been missing for a while has usually exposed something worth seeing.

Making sure it is the right one

  • Match the part number moulded into the liner. Front and rear differ, the two sides differ, and a model with wider arches takes a different part again.
  • Count the fixing holes and compare their positions with the old liner. This is the quickest way to tell two similar liners apart.
  • Check whether yours has cut-outs or ducts for brake cooling, a sensor or a washer line. These vary by specification.
  • Compare the material. The same position is made as hard plastic on one version and as a felted shell on another, and they use different fixings.

What to look for in the photographs

A Part number — Moulded into the inner face. It is often the only difference between two liners that look the same.
B Fixing holes — The holes, slots and rivet points around the edge. Count them and compare the spacing with your own liner.
C Cut-outs and ducts — Any opening for brake cooling, a sensor or a washer line. These vary by specification and are part of the match.
D Edge condition — Look along the whole rim, particularly where the fixings pass through. This is where a liner tears out.
E Material — Hard plastic or a felted shell. They are not interchangeable and they take different fixings.
