About part number 8U0853817A

A wheel arch trim is an exterior bodywork panel that fixes to the rear wing around the wheel opening. It protects the surrounding paintwork from road grit, stones, and water thrown up by the tyre, while giving the vehicle a clean finish. When the trim is fitted correctly, it sits flush against the bodywork and prevents spray from reaching the inner edges of the wing panel.

To ensure this is the correct part for your vehicle, check that the part number 8U0853817A matches the number stamped on your original trim. On plastic mouldings of this type, the part number is usually moulded directly into the reverse side of the plastic. Matching the exact part number is the only way to confirm correct fitment and alignment with the body panels.

These trims are usually replaced after sustaining scuffs, impact damage, or when the plastic fixing clips snap during removal. When fitting a replacement wheel arch trim, a technician will typically need new plastic mounting clips or trim fasteners, as the original plastic clips often break or lose their tension when the old trim is detached.

About this kind of part: trim mouldings

A trim moulding is a long, narrow strip that finishes an edge or a joint on the outside of a car: a door moulding, a sill cover, a wheel arch trim, a window finisher or a roof strip. Most are plastic, either painted to match the body or supplied in a textured black or a bright finish, and they clip to studs or to double-sided tape. They are cosmetic rather than structural, but they also cover the panel joint underneath, so a missing one leaves a gap where water and grit collect.

Why people replace one

  • A knock or a car wash has pulled the moulding away and broken the clips behind it.
  • The painted finish has chipped along the leading edge, which happens from stone strike on anything low down.
  • A textured black trim has gone grey and chalky in the sun, which cannot be cleaned back.
  • The double-sided tape has let go in the heat, so the strip lifts at one end and flaps.
  • A panel has been replaced and the original trim was broken getting it off.

Fitting it

  • A clipped moulding comes off by releasing each clip in turn from one end rather than pulling in the middle, where it will crack.
  • The clips themselves are usually separate parts and are normally replaced rather than reused, because they stretch once they have been off.
  • A taped moulding needs the old adhesive cleaned off the panel and new tape of the correct width, applied to a warm, dry panel.
  • Check which way up the strip goes before fitting. Many are handed and look symmetrical.

Making sure it is the right one

  • Match the part number. A moulding from the front door and one from the rear door of the same car are different lengths and different numbers, and so are the two sides.
  • If the trim is a wheel arch or a sill, check whether yours has openings for parking sensors. One without the openings cannot be used on a car that has them.
  • Compare the finish: the same moulding is made painted, in textured black and in a bright finish, and each is a separate number.
  • Count the clip positions along the back and compare them with the studs on your own car.

What to look for in the photographs

A Part number — Moulded or printed on the back face, usually towards one end.
B Clip positions — The row of clip seats or studs along the back. Count them and compare the spacing with your own car.
C Sensor openings — Openings for parking sensors, where the trim is an arch or a sill. Their presence or absence decides whether it fits your car.
D End profile — The shape of each end, which is what tells a front strip from a rear one and one side from the other.
E Leading edge — Look along the lower or forward edge, where stone chipping collects. It is the part a flat photograph flatters most.
F Tape or clip channel — Whether the back has a tape bed or a clip channel. These are not interchangeable.
