What is the fault code for the diesel parking heater?
2 Answers
The fault code for the diesel parking heater is e08. Common faults of the diesel parking heater include: No response after startup: Caused by no power input; Indicator light stays on: Possibly due to damaged control circuit or ungrounded wire; Heater emits black smoke: Caused by severe carbon buildup in the heater, requiring carbon cleaning, or due to clogged fuel injector, filter, or fuel line, necessitating cleaning or replacement of corresponding parts; Heater operates normally but repeatedly shuts off: Caused by the internal heating wire of the thermocouple connecting with the casing when heated, resulting in a short circuit of the ignition sensor. The controller interprets this as a shutdown, requiring replacement of the ignition sensor.
Trouble codes on diesel parking heaters can be a real headache! Common ones include E01 indicating ignition failure, which could be due to fuel line blockage or spark plug issues; E02 means overheating protection activated—check the cooling fan and water pump; E03 signals voltage abnormality—inspect if the battery is low on charge; E04 points to water pump failure, possibly from a stuck impeller; E05 indicates burner problems, often caused by excessive carbon buildup. On my vehicle's heater, E01 always means the fuel filter is dirty, and replacing the small filter cartridge solves it. However, seasoned drivers advise not to push through—when a code appears, shut off and inspect immediately to avoid turning minor issues into major faults. Codes vary slightly by brand—for instance, Tuoniu uses P01 for ignition problems, while Webasto has its own system. It’s best to keep the manual handy or save a photo of the fault code table on your phone.
