@Rok_Dr , the coolant purge procedure in the supplement appear to be for the B57. It didn’t work for me on a B58. It kept cancelling the process.
I found an old document from somewhere in the forum a while back with a flow chart of the procedure for the B58 and that one worked. These are the steps I used:
- Cold engine (coolant <50° C) and levelled car.
- Top up both reservoirs to max level, don’t overfill.
- Close bonnet.
- Handbrake on.
- Gearbox in P.
- Auto A/C off.
- Temperature knob to maximum and Fan to 1.
- Turn ignition to on position (engine still off)
- Press the accelerator pedal 100% for at least 10 seconds.
- Release accelerator pedal and press the brake pedal.
- Start the engine within 30 seconds of releasing accelerator pedal.
- After a few seconds, “Service Started” appears on the display.
- Wait at least 11 minutes. The engine will automatically rev up and down a few times.
- After 11 minutes “Service Ended” appears on the display.
- Top up coolant in both reservoirs to the max level, don’t overfill.
