There are various reason for the electric parking brake not showing its effect.
- There might not be sufficient voltage (Are you using a battery charger?)
- There might not be an electric parking brake.
- There might be an fault code in your brake system / ABS system.
- The electric parking brake might be damaged or stuck.
Of course, if you’ve eliminated all of these potential disruptive factors and still can not make an impact, our support team will always be there to help.
In that case, we would ask you to send us a brief e-mail with the error description to BMW@mycarly.com for BMW models or VAG@mycarly.com for VAG models, and we will try to remedy this as soon as possible.
