Leon Mk2

High pressure system pressure reduction.
High pressure system pressure reduction.
  WARNING
The injection system is in a high pressure system (max. approx. 120 bar) and a low pressure system (approx. 6 bar).
The fuel pressure in the high-pressure section must be reduced to a residual pressure of 6 bar prior to opening the high-pressure system. The procedure to do so is described below.
–  Carry out the → Vehicle diagnostic, testing and information system VAS 5051 connection and the guided function „reduce the high pressure of the fuel“.
–  Switch ignition OFF.
  WARNING
The fuel piping is exposed to fuel pressure. Wear safety goggles and appropriate clothing to avoid injury and contact with skin. Before opening the high-pressure system, place a cloth around the connection.
–  Place a clean cloth around the line connection, and open it carefully to eliminate the residual pressure of approx. 6 bar. Any spilt fuel must be cleaned up.
–  Once the work has been completed, consult the fault memory and erase all faults in memory due to disconnecting the connector.
  Note
If the fault memory has been deleted, the readiness code must be generated: → Vehicle diagnostic, testing and information system VAS 5051„Guided Fault Finding“.
