Removing and installing parts of the exhaust gas recirculation system for engine with engine identification characters BKD, AZV
  Note
t  The exhaust gas recirculation system is actuated by the diesel direct injection system control unit -J248- via the electro-pneumatic EGR valve -N18- in the solenoid valve block to the mechanical exhaust gas recirculation valve.
t  The mechanical exhaust gas recirculation valve with conically shaped valve tappet makes it possible to achieve different opening cross-sections at different valve strokes.
t  Any desired valve plunger position is possible as a result of the pulsed operation.
t  The exhaust gas recirculation switches off at idling speed after about two minutes.
t  When taking longer measurements, restart the engine or increase engine speed briefly to more than 1500 rpm. After this repeat the measurement.
t  Secure all hose connections with corresponding hose clips.
t  Replace self-locking nuts.
