Information
Guided Fault Finding using the PIWIS Tester as well as the DME short test "Valve lift" must be performed before replacing the hydraulic valve. This
is essential in order to avoid replacing the hydraulic valve unnecessarily. The hydraulic valves lie on the rear side of the cylinder heads facing the
plenum panel (under vacuum pump and fuel high-pressure pump).
1. Remove cross panel.
2. Cylinder bank 1 to 4: Remove vacuum pump.
3. Cylinder bank 5 to 8: Detach water tube.
4. Remove support for cooling water tube -7-. To do this, remove hexagon-head bolt -6-.
