How can I renew my dfreeeze license
You can renew your dfreeeze license directly in your dfreeeze app. The following payment methods are available: Paypal, direct debit, GiroPay and bank transfer.
How long can I continue to use dfreeeze and renew licences?
Activated systems with a valid licence can still be used until 30. June 2026. The full range of functions of dfreeeze is retained until the end. You can continue to extend current licences as usual in the dfreeeze app. From the end of June 2023, 3-year licences will no longer be available for licence renewal. 12-month licences can still be purchased from July 2023 until 30. June 2025. After that, 9-, 6- and 3-month licences will still be available to extend existing licences until the end-of-service on 30. June 2026. Please note: dfreeeze licences expiring after 1. April 2026 cannot be extended afterwards! With a valid licence, you can still use your dfreeeze as usual until 30. June 2026.

Why can I no longer order a new dfreeeze system from VW Accessories?
After 10 years and many thousands of dfreeeze systems in use throughout Europe, the last unit from the final series has now been installed. There will be no subsequent production of new dfreeeze systems. Already activated systems with a valid licence can still be used until 30. June 2026. Licence extensions for active systems are still possible.

My parking heater is not reacting. Why is that?
First, please check whether your receiver was already installed in the vehicle when you performed the initialisation.
Initialisation was successful if the status display shows the message “Initialisation successful software version ############”.
If the receiver has already been connected but you are still not receiving the message, that may be because the receiver cannot connect to the mobile phone network. In this case you should move your vehicle to a location with better reception. Then perform the initialisation again.
The app does not recognise my installed receiver!
Once you have set up your vehicle in the app (see section 3.3 in the user manual), the status display should show the following message: “Initialisation performed software version xxxxxxxxxx”. This indicates that your dfreeeze receiver was installed correctly and has mobile phone reception.
Please note that initialisation can only be successful if the receiver has mobile phone reception and a power supply.
How can an "authorised user" log in?
- the vehicle name
- the telephone number of the dfreeeze (D200 number, starting with +49...) and
- the 4-digit PIN code (chosen by the main user at the first initialisation).
How much does dfreeeze cost?
What do I have to do when I sell my car with dfreeeze?
The new owner needs at least the 8-digit serial number (with this number the dfreeeze can be clearly identified) and he should contact customer service to get all further data and a new verification key. The licence is not automatically renewed, bank details are not stored.
What do the different comfort levels 1-5 mean?
The comfort level determines the running time of the parking heater. Comfort level 1 is the lowest (max. running time 20 minutes) and comfort level 5 is the highest (max. running time 60 minutes). The running time always depends on the temperature.
What is the 4-digit PIN needed for?
The PIN is important for the "authorised users" so that they can create the vehicle in the app.
Where can I find the D200 number?
The D200 number (starting with +49...) is the phone number of the dfreeeze's built-in sim card. You can find it on the label of the dfreeeze module and on the sticker that comes with the box.
Where can I find the Verification Key?
The Verification Key is noted on the sticker that comes with dfreeeze. If it is lost, please contact customer support (dfreeeze [at] digades.de (dfreeeze[at]digades[dot]de)).
Where can I get the 4-digit PIN?
You choose the 4-digit PIN by yourself.
Where is the serial number stored in the app?
The serial number can be found in the app under "Settings".
