Here is how to bleed the cooling system on the i8
For the bleeding of the high-temperature cooling circuit proceed in the same way as the procedure for conventional vehicles. However, unlike in the low-temperature cooling circuit, the bleeding procedure does not end automatically, but must be independently completed by a Service employee.
1 Evacuate and fill cooling system using vacuum filling device. Remove the vacuum filling device after the filling procedure is completed.
2 When the expansion tank is open, open the bleeder screw for 20 seconds.
3 Close the bleeder screw and expansion tank again.
4 Terminal 15 ON, set IHKA controls to 28 °C / 82 °F at blower speed 1 and "Air conditioning OFF".
5 Press the accelerator pedal for about 20 seconds at full load (engine OFF).
6 Start combustion engine in selector lever position "P" with Automatic Hold brake engaged.
7 Increase engine speed using accelerator pedal 4 times for about 5 to 10 seconds to roughly 3500 rpm, with a 10 second interval between the respective engine speed increases. Repeat procedure every 2 minutes for about 16 to 18 minutes.
8 Increase engine speed using accelerator pedal 4 times for about 5 to 10 seconds to roughly 5500 rpm, with a 10 second interval between the respective engine speed increases.
9 After 20 minutes carry out a test drive in selector lever position "S" and with heating turned on fully.
10 The ventilation is completed as soon as hot air flows continuously from the air outlets.
11 Adapt coolant in the cooled down state to MAX filling level.
