BMW 3 Series Wing Mirror: Specs, Fitment & Common Faults
Confirmed: an official BMW bulletin explains a power-fold mirror's home position can genuinely shift and get incorrectly stored — plus a useful finding that facelift models have no separate mirror control module, with the driver's side controlling both.

More Electronics Hiding Inside Than Most People Realise
What looks like a simple glass-and-plastic assembly on the outside is often anything but on the BMW 3 Series: its wing mirrors typically house folding motors, heating elements, indicator lights, and sometimes blind-spot sensors, so a "faulty mirror" isn't really one specific fault.
BMW 3 Series Wing Mirror: Driver's Side or Passenger Side? Sorting Out the Terminology
One thing worth getting right before you buy a BMW 3 Series wing mirror: terminology for left and right isn't applied consistently across UK retailers and parts catalogues, which trips up plenty of buyers. On a right-hand-drive UK car, the convention runs like this:
- 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 3 Series. 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.

This is a genuinely variation-heavy part on the G20 — beyond the driver's/passenger's side question covered above, confirm heated glass, folding function, and whether your car has a blind-spot monitoring camera or memory function built into the mirror housing before ordering.
BMW 3 Series Wing Mirror: What It Does
Beyond the obvious job of rear visibility, modern wing mirrors on higher trims of the 3 Series 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.

Confirmed: A Genuine Official Bulletin Worth Knowing About — BMW 3 Series Wing Mirror
If a power-fold mirror appears to be sitting further out than it should when folded away, this is genuinely worth knowing directly from an official BMW service bulletin covering this model: the mirror housing's stored "home" position can genuinely shift outward over time, with this incorrect new position then being saved as the new reference point. Simply folding the mirror in and out repeatedly does not correct this, and the official bulletin explicitly states that no parts should be replaced for this specific fault, worth asking a specialist about the proper reset procedure instead.
It's also genuinely worth knowing that an internal spring and locking pin mechanism needs to properly engage for a manually folded mirror to work correctly, and that this pin can become dirty and stuck, causing premature wear on surrounding components.
