My Z4 M40i has had the intercooler/radiator changed after sustaining some damage following accident repair. The garage is trying to bleed the system, but cannot get the electric pumps to activate. tried the sequence of:
1. Ignition on.
2. Headlight on manually.
3. Fan on minimum.
4. Heat on full.
5. Hazards on.
6. Holding accelerator down for 15 seconds.
Followed the instructions from the video below but pump is not starting bleed process. Where are we going wrong?
