Automatic folding mirrors are a popular convenience feature available on many modern Audi vehicles. They allow the side mirrors to fold automatically when the vehicle is locked, improving protection in tight parking spaces while adding a premium appearance.

However, some Audi owners experience a problem where the mirrors stop folding automatically after locking the vehicle.

In many cases, the mirror mechanism itself is not damaged. The issue is often related to Audi MMI settings, coding changes, door control module communication, software updates, or vehicle configuration.

Modern Audi vehicles use advanced electronic control systems where comfort functions are managed through modules rather than traditional mechanical switches. The folding mirror system depends on communication between the mirror motors, door modules, central locking system, and vehicle software.

This guide explains why Audi mirrors stop folding when locking, how to check MMI settings, coding solutions, retrofit requirements, repair costs, and when specialist support may be needed.

Why Are My Audi Mirrors Not Folding When I Lock the Car?

Audi automatic folding mirrors depend on multiple systems working together:

• Folding mirror motors
  
• Door control modules
  
• MMI convenience settings
  
• Vehicle coding
  
• Central locking system
  
• Electrical communication
  

A fault in any of these areas can prevent the mirrors from folding automatically even when the mirrors work manually.

1. Audi Mirror Folding Function Disabled in MMI Settings

One of the most common reasons Audi mirrors do not fold automatically is that the function has been disabled through the MMI system.

Many Audi owners assume the mirror motor has failed, but the feature may simply be switched off in the vehicle settings.

How to check Audi folding mirror settings:

1. Turn the ignition on.
   
2. Open the MMI system.
   
3. Navigate to:
   

MMI → Vehicle → Central Locking → Fold Mirrors

4. Confirm that automatic folding is activated.
   

If this setting is disabled:

• Mirrors may still fold manually.
  
• Mirrors will remain open after locking the vehicle.
  

Checking MMI settings should always be the first step before replacing mirror components.

2. Audi Coding Has Been Changed or Reset

Many Audi comfort features depend on coding stored within vehicle control modules.

Automatic folding mirrors may stop working after:

• Battery replacement
  
• ECU software updates
  
• Vehicle resets
  
• Incorrect coding changes
  
• Module replacement
  

Audi coding tools such as:

• VCDS
  
• OBDeleven
  

can modify supported vehicle functions.

Some Audi models leave the factory with electrically folding mirror hardware installed, but the feature may not be activated because of:

• Market specifications
  
• Trim level differences
  
• Previous owner modifications
  
• Factory configuration settings
  

Restoring the correct coding can often reactivate automatic folding without replacing the mirror assembly.

3. Audi Mirrors Fold Manually But Not When Locking

This is one of the most useful diagnostic clues.

If your Audi mirrors fold using the mirror adjustment switch but do not fold when locking, it usually indicates:

• Mirror motors are working.
  
• Electrical supply is available.
  
• The problem is likely related to settings, coding, or communication.
  

Possible solutions include:

Check MMI settings

Confirm the folding mirror option is enabled.

Check vehicle coding

Incorrect coding can disable automatic folding behaviour.

Scan door control modules

A diagnostic scan can identify faults involving:

• Mirror modules
  
• Door electronics
  
• Central locking system
  

4. Audi Door Control Module Communication Fault

Audi mirror functions rely heavily on communication between electronic control units.

A fault in the door control module can prevent automatic folding.

Possible symptoms include:

• Mirrors stop folding suddenly.
  
• One mirror works while the other does not.
  
• Other door functions behave incorrectly.
  
• Folding option disappears from MMI.
  

A professional diagnostic scan can identify communication errors and determine whether the problem is caused by software or hardware.

5. Audi Folding Mirror Motor or Hardware Failure

Although software and coding issues are common, physical mirror failures can also occur.

Signs of Audi mirror hardware failure:

• Clicking noises from mirror housing.
  
• Mirror movement stops halfway.
  
• One mirror folds incorrectly.
  
• Folding button does not operate the mirror.
  
• Grinding sounds during operation.
  

Professional diagnosis may include:

• Checking fault codes.
  
• Testing mirror motor operation.
  
• Checking electrical supply.
  
• Inspecting wiring.
  
• Testing door module communication.
  

Replacing the complete mirror assembly should only be considered after confirming the failed component.

Audi Models Commonly Affected by Folding Mirror Issues

Audi folding mirror configuration problems can occur on several models, including:

• Audi A3
  
• Audi A4
  
• Audi A5
  
• Audi Q3
  
• Audi Q5
  
• Audi Q7

The exact cause depends on the ve

hicle generation, installed equipment, and software configuration.

Audi Folding Mirror Retrofit Requirements

Some Audi models do not have automatic folding mirrors installed from the factory.

A complete retrofit may require additional components.

Audi folding mirror retrofit may include:

• Compatible folding mirror motors.
  
• Suitable door control modules.
  
• Additional wiring.
  
• Mirror switch upgrades.
  
• Software coding.
  

Before installing folding mirrors, vehicle compatibility should be checked.

Installing incompatible components can lead to:

• Communication errors.
  
• Incorrect mirror operation.
  
• Additional electrical faults.
  

A professional assessment helps ensure the correct retrofit approach.

Audi Folding Mirror Troubleshooting Checklist

Before replacing parts, check:

Can Audi Mirrors Be Coded To Fold When Locking?

Yes, many Audi models support automatic mirror folding activation through coding.

Using tools such as:

• VCDS
  
• OBDeleven
  

A specialist can check whether the feature is supported.

Coding may activate the function if:

• Folding mirror hardware is installed.
  
• Door modules support the feature.
  
• Vehicle software allows activation.
  

If hardware is missing, coding alone will not enable automatic folding.

How Much Does Audi Folding Mirror Repair Cost in the UK?

Audi folding mirror repair costs depend on whether the issue is software-related or requires replacement parts.

Costs may increase on higher-spec Audi vehicles because mirror assemblies can include:

• Blind spot monitoring sensors.
  
• Integrated cameras.
  
• Memory functions.
  
• Auto-dimming glass.
  
• Heating elements.
  
• Power adjustment systems.
  

Correct diagnosis helps avoid unnecessary replacement costs.

Can I Fix Audi Folding Mirrors Myself?

Some Audi folding mirror issues can be solved with basic checks.

Safe DIY checks include:

• Checking MMI folding mirror settings
• Testing manual mirror operation
• Checking vehicle key settings
• Reviewing fuse information
• Restarting vehicle electronics

Avoid:

• Changing coding without understanding Audi systems
• Replacing door modules without diagnosis
• Installing incompatible folding mirrors
• Opening mirror motors without experience

Audi vehicles use complex electronic systems, and incorrect changes may create additional faults.

When Should You Contact an Audi Specialist?

Professional support is recommended when:

• Mirrors suddenly stop folding.
  
• One mirror operates incorrectly.
  
• Coding does not restore the function.
  
• The vehicle requires folding mirror retrofit.
  
• Door modules show communication faults.
  
• Replacement parts need programming.
