On 5-series (E39), 7-series (E38) and the X5 (E53) the parking heater can be activated with software. You can then set timers via the monitor in the car to have the car warm up automatically during cold winter mornings.
Your parking heater can be activated if your car meets the following requirements:
Your 5-series (E39) is from October 2000 or younger and it is a 6-cylinder diesel.
Your 7-series (E38) is from 1999 or younger and it is a 3.0 liter 6-cylinder diesel.
Your X5 (E53) is from 2001 or younger and it is a 3.0 liter 6-cylinder diesel.
Please note: This is only about software activation of the parking heater functionality. This only works on vehicles where the hardware (Webasto unit) is already present. With the above noted types that is the case.
Furthermore, for the functioning of the parking heater it is important that all components also function properly. Because the units have not been used in the past 15 years, it is possible that certain parts no longer function. That’s why we read the car free of charge for any malfunctions in the parking heater, so that you can have them repaired if there are any malfunctions. BMW Tweaks only provides software activation. For repairs we would like to refer you to a specialist.
