Proceed with MoDiC or DIS. This switches off the auxiliary water
pump and no coolant can emerge after the expansion tank has
been opened.
Relieve pressure from cooling system. Remove special tool
17 0 002/005 from expansion tank, if necessary top up
expansion tank back to top again.
The venting of the latent heat accumulator/heating circuit is thus

Vent engine circuit.
Allow engine to run for brief period with cooling system open and
rinse the engine cooling circuit by briefly pressing accelerator
pedal three to four times (up to approx. 5000 rpm). Switch engine
off again to prevent the coolant from heating up too much, which
would enable it to expand.
If necessary, fill expansion tank back up to top edge and refit the
screw cover.
Proceed with MoDiC or DIS. This switches on the auxiliary water
pump again and the valve unit and the water valves are set in
such a way that the line from the engine to the heating circuit is
also vented.
