Introduction to the causes of Eberspacher parking heater malfunctions: Possible reasons for fault codes appearing: If the heating effect is not obvious, it may be due to a too narrow water return port; gas trapped in the circulation water circuit; rubber hoses being bent; blockages caused by foreign objects in the circulation pipeline; water pump failure; inlet and return water valves not being opened; the engine thermostat opening too early, etc. Identify the cause and carry out corresponding repairs. Precautions for parking heaters: It is necessary to avoid the components around the parking heater and other parts being affected by overheating or contaminated by fuel or engine oil. The parking heater itself must not pose a fire risk even when overheating. As long as during installation, attention is paid to maintaining a satisfactory distance between the parking heater and all other components, and ensuring good ventilation and the use of fire-resistant materials or heat shields, the above requirements can be considered satisfied.
I've driven many cars and often encountered parking heater failures, mainly due to insufficient battery power or aging. In winter, they won't start when it's cold, so you need to check if the fuse is blown. The fuel system is also prone to issues, like clogged fuel lines or poor fuel quality—try adding some cleaner. There's also poor contact in the control switch, damp or loose wiring—I've experienced this several times myself, and a simple reconnection can fix it. Don’t forget fan or pump failures; be alert to unusual sounds. I recommend regular maintenance, cleaning carbon deposits and dust, rather than waiting for problems to arise—it’s both hassle-free and safer.
