Wondering how to make extra heating in your car? A diesel parking heater may be the solution.
Order / Cost
“Chinese Webasto” we can buy on Aliexpress.com and Allegro.pl.
I ordered from Aliexpress in December 2020 from the link: https://s.click.aliexpress.com/e/_AOt3OV Delivery from the Czech Republic in a few days by courier to your door. Cost ~£100 (the price also fluctuates with the dollar exchange rate). It fell on 5kW (2kw was no longer available).

Thanks to coupons, the cost with delivery from Poland comes out to ~415PLN
To claim coupons, add the product to your cart from the link above, then go to the store's home page and click claim coupon. You can pick up multiple coupons.
We can also order from Allegro, but it seems to me that it goes through Aliexpress anyway, since the topping all sellers are from China or another exotic country. On Allegro you can find them in the section: Automotive -> Car parts -> Parking heating and car cooling -> Parking heating -> Complete installations.
On Allegro, the same set (it looks like from the same seller) is slightly more expensive:
Installation of parking heater / Webasto
We'll get assembly instructions, but looking at the kit it's easy to figure out what should go where. In addition, there are plenty of YouTube videos, including in Polish.
In my case, it fell on the place under the car in the region of the original parking heater in the T4. To protect the heating, the housing was made to order to size, but you can easily find similar ready-made housings on Allegro right now.
Attention! Before the first startup, first fill the system with fuel by starting the fuel pump first. To do this, hold down two buttons on the controller: Settings + down arrow, then change to “On”. When the layout is full, we can change to “Off”, exit to the main menu by clicking Settings. It is now safe to start the parking heater.
To enter the service menu, enter the code in the last item of the normal menu: 1688. From this menu, change the minimum and maximum values for the Hz fuel pump and blower fan speed, change the voltage between 12V and 24V,
Pairing the remote control
To pair the remote control with the heater, hold down the button with the up arrow on the controller (in the case of the controller as below left) until the word HFA- appears . Then just click “On” on the remote control and you're done.
All you have to do is hold down the button marked with an up arrow on the controller until the display shows “HFA” and then press the button that turns on the heating on the remote control. The devices should pair and the furnace should start, which will be indicated by the message “ON” on the display
Burning primarily depends on the power of the stove itself and the frequency of the fuel pump, which we can set ourselves. Average combustion for minimum values of 1.6Hz – 0.15l/h, for high values of 5.5Hz – 0.35l/h
The instructions are sent in English. If you would like it translated, please write a comment. At my leisure, I may be able to translate it.

To access the advanced settings of the Chinese webasto, click the settings button 3 times. Then enter the code: 1688. This will give us access to more settings. As these are advanced settings additionally protected by a pin, change them if you know what you are doing.
- E-01 – Voltage too low. Recharge the battery, increase the voltage above 12V.
- E-02 – Voltage too high. Reduce the voltage below 15V.
- E-03 – Glow Candle. Check the bulb candle, and the cable leading to it.
- E-04 – Fuel Pump. Check the fuel pump, and the cable leading to it.
- E-05 – Overheating. Check the temperature sensor, the fan, the patency of the ventilation ducts (can occur when you use ducts with a smaller diameter than standard).
- E-06 – Drive / Motor. Check the motor, magnet polarity, Molzer sensor, power cable.
- E-07 – Defective connection. Check the plug, wiring.
- E-08 – Emergency Shutdown. Check the patency of the fuel lines, check the fuel filter for air, check the housing temperature sensor.
- E-09 – Sensor Error. Check the temperature sensor, plug and wiring.
- E-10 – Ignition Error. Check the patency of fuel lines, fuel density, fuel pump.
Error E-10 usually occurs at the first startup, when the fuel does not have time to reach the stove. The simplest solution is to restart the whole procedure and, if possible, shorten the fuel hoses.
The quality compared to the price is very high, considering that equipment from other brands like Webasto, Eberspacher can be many times higher.
Although parking heaters such as Webasto, Eberspacher, or Chinese equivalents are safe when properly connected, it is a good idea to include a carbon monoxide (chad) detector in the room where you use them.
