Enable Folding Mirrors on Lock
The most popular coding there is: the mirrors fold in when you lock the car and unfold when you unlock it. It protects the mirrors in tight spots, looks properly premium, and takes about five minutes. The one catch — your car needs powered folding mirrors in the first place. Here's how to do it.
Your car must have power-folding mirrors
Coding only changes when the fold motors trigger — it can't add motors that aren't there. If your mirrors already fold via the button in the door (or from the iDrive menu), you're good. If they don't fold at all, no coding will make them; that needs a hardware change. Quick check: try the mirror-fold function from the door switch first.
What It Actually Does
Triggers the fold motors off the lock signal.
Cars with power-folding mirrors can already fold them manually, but BimmerCode lets you tie that to the central locking: fold on lock, unfold on unlock (some cars also offer "unfold on drive-off"). It's a single setting change, fully reversible, and changes nothing mechanical — it just tells the body module to fold the mirrors when you lock up.
Before you start
Confirm your car's supported, use a supported adapter, and follow the safe coding routine — stable voltage, one change at a time, and note the original value so you can revert.
How It's Done
By control unit — the way the app is actually laid out.
Connect to the Car
Plug the adapter into the OBD port, ignition on (engine running or a charger connected for stable voltage), open BimmerCode and tap Connect. Let it identify the car and read the control units.
Pick the Vehicle & Use Standard Mode
Select your vehicle and choose Standard mode for plain-language toggles. You'll land on the Control units list — each with a short description of what it controls.
Open the "Front Electronic Module"
Mirrors live with the body functions — tap the Front Electronic Module, described as "Auto Start Stop function, doors/windows, lighting, mirrors." The name can read Body Domain Controller on some chassis, so go by the description (it mentions mirrors).
Find the Mirror-Fold Setting & Note It
Find the option for folding mirrors on lock/unlock, and record its current value first (screenshot or note) — this is your undo. Never skip it.
Enable It, Then Code
Turn on "fold mirrors on lock" (and "unfold on unlock"/"on drive-off" if offered), then tap the code/checkmark (write) button. Change only this one setting this session.
Test It
Lock the car and watch the mirrors fold; unlock and watch them return. If they do, you're done — if not, re-check you opened the right unit and that the car has power-fold mirrors.
Reverting It
Back to factory in seconds.
To undo it — for a dealer visit or just to go stock — set the value back to the original you recorded and code it; the mirrors stop folding on lock, exactly as before. This is why the safe routine has you note the original first. See reverting to factory coding on the hub.
FAQ
Will this work if my mirrors don't fold?
No. The coding only changes when the fold motors trigger — it can't add folding hardware. If your mirrors fold via the door switch or iDrive, coding will tie that to locking; if they don't fold at all, you'd need the powered-fold hardware first. Test the door switch to check.
Which control unit is it in?
The Front Electronic Module (described in the app as covering "Auto Start Stop function, doors/windows, lighting, mirrors"). On some chassis the equivalent is named Body Domain Controller — go by the description that mentions mirrors rather than the exact name.
Can I also unfold them automatically?
Many cars offer "unfold on unlock" and/or "unfold on drive-off" alongside "fold on lock" — enable whichever combination you like. The options available depend on your car; the app shows what's supported.
Is it safe / reversible?
Yes — it's a single body-module setting, nothing mechanical, and fully reversible by restoring the original value. Follow the usual care: stable voltage, supported adapter, one change at a time, original value noted.
Will it drain the battery folding every time?
No meaningful effect — the fold motors draw briefly, just as they do when you fold them manually. If the car sits for long periods, keep the 12V healthy with a maintainer anyway.
The Bottom Line
It's the first coding most people do, and for good reason — a five-minute, fully reversible change that protects the mirrors and feels premium. Just make sure your car has power-folding mirrors, open the Front Electronic Module (the one whose description mentions mirrors), enable fold-on-lock, and code it.
