I have an Audi A5 Sline Sportback Facelift 2012 Auto

I can engaged the parking brake using the electronic handbrake manually switch been pull upward and I can release the brake when I pressed the acceleration pedal.

The brake will NOT release if I press the electronic handbrake switch downward.

This has never been a problem for me as I don't manually release the handbrake using the electronic handbrake switch, only using the acceleration pedal.

Lately, I have had some complaint from MOT centre saying I should be able to release the handbrake manually using the electronic handbrake switch.

No error showing in VCDS relating handbrake

My question is,

Is this normal?

Should I been able to release the handbrake using the electronic handbrake switch?

Do I have a faulty switch?

Is there a setting within VCDS that I need to enable?

Thanks for your help

In order to release the electronic handbrake, by pressing down the handbrake switch, you must have yr foot on the brake pedal.
In my pré-facelift A5, I did change that, so I could release the handbrake all the time.
but this can be dangerous, if the switch is pressed accidentally.
  1. Select module 53 - Parking brake
  2. Select Security Access - 16 and enter the code from the popup screen (25194 - pré-facelift / 78713 - facelift)
  3. [Adaptation - 10] --> channel 04 – Click on ‘Read’,
  4. Change the value into “0” ( = inactive)

I tried all that and it don't work

Also, my 53 - Parking brake module channel has many options but I do have "Manual release"

I set Manual release with button and brake pedal depressed and it's not working
