Mercedes-Benz A-Class Wing Mirror: Specs, Fitment & Common Faults

A genuinely useful DIY fix: a penetrating lubricant applied to the fold mechanism has resolved stiff or squealing mirrors — plus a finding that a battery disconnect or diagnostic reset can fix auto-fold suddenly not working despite the setting being enabled.

Mercedes-Benz A-Class Wing Mirror: OEM Part Number

Accuracy note: genuinely worth knowing: A-Class owners have reported mirror glass replacement alone (rather than the entire housing) as a genuinely cheaper fix for cracked or damaged glass specifically, where the housing and motor are otherwise undamaged — worth checking if just the glass is available before assuming a full mirror assembly is needed.

Mercedes-Benz A-Class Wing Mirror: More Electronics Hiding Inside Than Most People Realise

Don't let the simple exterior fool you — the Mercedes-Benz A-Class's wing mirrors are built around folding motors, heating elements, indicator lights, and sometimes blind-spot sensors, all packed behind the glass, which is why "the mirror's playing up" covers a lot of ground.

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.

Mercedes-Benz A-Class Wing Mirror: Driver's Side or Passenger Side? Sorting Out the Terminology

It sounds simple, but Mercedes-Benz A-Class wing mirror side is one of the more commonly mixed-up orders — largely because UK retailers, workshops and catalogues use inconsistent left/right terminology. Here's the actual convention for right-hand-drive UK cars:

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 A-Class. 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.

Mercedes-Benz A-Class Wing Mirror: What It Does

Beyond the obvious job of rear visibility, modern wing mirrors on higher trims of the A-Class 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.

Mercedes-Benz A-Class 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.

W176 (2012–2018), standard trims	Cirrus White, Calcite White, Mountain Grey, Polar Silver, Night Black; 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
W177 (2018–present), standard trims	Polar White (no-cost), Cosmos Black, Digital White, Denim Blue, Patagonia Red, Iridium Silver; 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
W177 AMG Line	Same core palette as standard trims; electric adjustment and heated glass are standard on this trim
W177 A45 S AMG "Green Hell Magno" Limited Edition (2024)	A genuinely unique matte green ("Green Hell Magno") with yellow wheels and decals, not available on any other A-Class derivative; electric adjustment and heated glass are standard on this trim

A Genuinely Useful DIY Fix Worth Knowing — Mercedes-Benz A-Class Wing Mirror

If a mirror is folding stiffly, squealing, or only folding partway, this is genuinely worth trying: applying a penetrating lubricant to the fold mechanism itself has resolved a stiff or squealing mirror in documented cases, worth trying this simple, inexpensive step before assuming a full mechanism replacement is needed. It's also genuinely worth knowing that if the mirrors have stopped auto-folding on locking despite the relevant setting being enabled in the infotainment menu, a battery disconnect for a short period, or a proper diagnostic reset, has resolved this specific glitch in documented cases.

A genuinely important, technical finding worth knowing: if a mirror folds in one direction but not the other, this genuinely rules out a broken wire as the cause, since a broken wire would prevent both directions from working, pointing instead toward the switch itself.

It's also genuinely worth knowing that wires inside the mirror housing can genuinely snap over time from the repeated folding and unfolding motion itself, worth asking about a wiring repair as a cheaper alternative to a full mirror frame replacement.
