Subaru Impreza Wing Mirror: Specs, Fitment & Common Faults

On the Impreza, UK-spec cars genuinely don't fold via the electric motor at all, despite the mirror unit being physically the same as the JDM part.

OEM Part Number: confirm via VIN — Aftermarket Van Wezel 5155807 (LH) / 5155808 (RH)

Accuracy note: Covers the fifth-generation Impreza (GT, 2017 on). Subaru genuine assemblies (91036 series, e.g. 91036SG323 left / 91036SG333 right on the Forester SJ in some markets) are colour- and spec-specific and sold by VIN. UK aftermarket catalogues list one shared set of Subaru references across the Forester, Impreza, XV and Outback of this era, so confirm the fit against your car before ordering. Mirror specification varies by trim — heated, power-folding, indicator, memory, puddle-light and blind-spot / lane-assist versions use different units and connector pin counts, so match the pin count and features of the mirror you are removing, or confirm against your VIN, before ordering. Aftermarket references are catalogue listings for this generation, not factory numbers.

Subaru Impreza Wing Mirror: More Electronics Hiding Inside Than Most People Realise

The Subaru Impreza's wing mirrors bundle a surprising amount of hardware behind that glass — folding motors, heating elements, indicator lights, sometimes blind-spot sensors — meaning a single vague complaint like "the mirror's not working" could describe several distinct faults.

Before you buy: mirror specification varies significantly by trim — heated, power-folding, indicator-integrated and blind-spot-sensor versions are not interchangeable. Always confirm against your VIN before ordering.

Subaru Impreza Wing Mirror: Driver's Side or Passenger Side? Sorting Out the Terminology

Side confusion is one of the most common ordering errors with Subaru Impreza wing mirrors, since UK sellers and catalogues don't always describe left and right the same way. Here's how it breaks down on a right-hand-drive UK car:

Driver's side = right-hand (RH) = offside (OS) — the side closest to the centre of the road.
Passenger side = left-hand (LH) = nearside (NS) — the side closest to the kerb.

Part listings may use any of these terms interchangeably — "RH mirror," "offside mirror," and "driver's side mirror" all refer to the same physical part on a UK-spec Impreza. Double-check which convention your supplier is using before ordering, since a mix-up here is one of the most common reasons the wrong mirror turns up.

Subaru Impreza Wing Mirror: What It Does

Beyond the obvious job of rear visibility, modern wing mirrors on higher trims of the Impreza often integrate turn signal repeaters, puddle lights, heating elements to clear condensation, and power-fold motors for tight parking spaces. Higher-spec versions may also house blind-spot monitoring sensors, making them considerably more expensive to replace than a basic mirror.

Subaru Impreza Wing Mirror: Generations, Derivatives, Colour & Mirror Adjustment

Accuracy note: mirror covers colour-match the body — see notes below. Manual vs. electric adjustment and heated glass are general patterns by trim and era, not a substitute for confirming your exact derivative via VIN, since even within one generation the base specification can differ from what's typical for that era. This applies equally to the driver's side and passenger side mirror, which always match in adjustment type and heating.

All generations	Crystal White Pearl, Crystal Black Silica, Ice Silver Metallic, Pure Red; electric adjustment is standard on most trims from this generation, with heated glass increasingly common too — though the most basic specification may still be manual; confirm your exact trim

A Genuinely Important UK-Specific Limitation Worth Knowing — Subaru Impreza Wing Mirror

This is genuinely worth knowing before assuming your mirror should power-fold: Japanese Domestic Market spec cars have an electric motor that folds the entire mirror housing in, but UK-spec cars genuinely don't fold via this motor at all, despite having what is physically the same mirror unit with the same folding components inside. UK buyers sourcing a replacement mirror are effectively paying for internal parts they can't use.

A genuinely useful, free reset trick worth trying before dismantling anything: if a mirror has gone "floppy," partially folding on its own while driving, try setting the fold switch to folded, then to unfolded, then pressing the button again. This has been documented resetting the internal mechanism in some cases without any disassembly at all.

It's also genuinely worth knowing that the auto-fold-on-lock feature doesn't work out of the box on UK-spec cars fitted with double-deadlocking central locking specifically — an additional relay is needed to acquire a re-open signal for this feature to function correctly.
