BMW F10 Webasto: how it works and common faults
What is the BMW F10 factory Webasto and is it standard equipment?
The factory Webasto is a Webasto Thermo Top V auxiliary heater. It is not standard but comes as an option in the ZWP winter package (option number 536). The type plate is found in the driver's side grille next to the fog light, behind the water hose.
Does the F10 Webasto start by itself?
Before the LCI update (facelift) the Webasto starts by itself when the outside temperature is below about +8 °C. In an LCI car it does not start by itself by default, but the setting can be changed by coding. While driving, the heater switches off when the coolant is about 75 degrees.
Why does the F10 Webasto not start or heat?
Common causes: the remote is not paired or its AAAA battery is flat, the circulation pump is faulty, the heater's glow plug or combustion chamber is dirty and gives a fault code, or the battery voltage is too low in freezing weather. Pairing and reading the fault is done by a workshop.
