♦ Open closed lines and connections immediately with suitable
screen caps.
♦ Place removed parts on a clean surface and cover. Do not use
fuzzy cloths!
♦ Only install clean components: Remove spare parts from their
wrapping immediately before fitting. Do not use any parts
which have been stored unwrapped (e.g. in tool boxes etc.).
♦ When the system is open: Do not work with compressed air.
Avoid moving the vehicle.
♦ Protect electrical plug connections from dirt and moisture and
only connect them when dry.
♦ The extraction hose of an exhaust extraction system which is
switched on, must be positioned close to the assembly open‐
ing of the fuel tank in order to extract the released fuel vapours,
even before the work is commenced. If no exhaust extraction
system is available, a radial fan (motor not in air flow of fan)
with a delivery volume of more than 15 m
♦ Prevent skin contact with fuel!
♦ Wear fuel-resistant gloves!
1.2.2 Reduce pressure in the high-pressure
system
Caution
The injection system consists of a high pressure part (max.
pressure of 12 MPa = 120 bar) and a low pressure part (pres‐
sure of approx. 0.7 MPa = 7 bar).
Before opening the high pressure system, e.g. removing the
high pressure pump, the fuel distributor, the injection valves,
the fuel pipes or the fuel pressure sender - G247- , the fuel
pressure in the high pressure system with a remaining pres‐
sure of approx. 0.7 MPa (7 bar) must be reduced.
– Connect the ⇒ Vehicle diagnostic tester and carry out the tar‐
geted function "remove high fuel pressure".
• The fuel pressure drops to a predetermined value.
– Switch off ignition.
– Before opening the fuel system, disconnect the plug from the
fuel pump control unit.
– Before opening the high pressure system, lay cleaning cloths
around the connection point.
– Open fuel system carefully to reduce the residual pressure of
0.7 MPa (7 bar) and when doing so collect fuel that is flowing
out.
