Testing preheating system
Check for proper operation
Special tools, test equipment and aids required
t  Handheld multimeter (e.g. -V.A.G 1526 A-)
t  Current flow diagram
Test conditions
l  Battery voltage min. 11,5 V
l  Diesel direct injection system control unit -J248 - O.K.
l  Fuses in fuse holder on battery O.K.
Test sequence
–  Switch off the ignition.
   
–  Disconnect plug -1- from Coolant temperature sender (-G62-) -2-.
  Note
By disconnecting the plug from the sender engine condition “cold” is simulated and when the ignition is switched on a corresponding preheating process is performed.
–  Remove the glow plug connectors from the glow plugs.
–  Connect the handheld multimeter for voltage measurement to a glow plug connector and engine mass.
–  Switch on the ignition. The approx. battery voltage must be displayed for approximately 20 seconds.
If no voltage is present:
–  If necessary eliminate wire interruption or short-circuit → Current flow diagrams, Electrical fault finding and Fitting locations.
During the simulated preheating process the glow period warning lamp -K29- must light up.
If the glow period warning lamp does not light up:
–  Test glow period warning lamp -K29- → Current flow diagrams, Electrical fault finding and Fitting locations.
