4.15 Checking glow plug continuity
CAUTION
• To
prevent an accidental short circuit, attach
the positive cable to the positive terminal before
the negative cable is attached to the negative
terminal.
• Do not remove the battery cap while the engine
operates.
• Keep electrolyte away from eyes, hands and
clothes.
If you are spattered with it, clean with water
immediately.
• Keep open sparks and flames away from the
battery at all times.
Hydrogen gas mixed with oxygen becomes very
explosive.
Tools required
• Circuit tester
1. Remove the glow plug (2).
2. Measure the
resistance with a circuit tester between
the glow plug terminal and the glow plug housing.
NOTE
• If the
measurement does not show the
service specification, the glow plug (2) is
damaged.
• Adjust the direction of the ditch to the
terminal side when the seal (1) is installed in
the glow plug (2).

4.16 Checking exhaust gas leakage
of turbocharger turbine side
1. Check the
exhaust port (3) and the inlet port (5)
side of the turbine housing (1) for exhaust gas
leakage.

NOTE
• If you
find a gas leakage, tighten the screws
and nuts again or replace the gasket (2) /
(4) / (6) with a new one.
4.17 Checking air leakage of
turbocharger compressor side
1. Check the inlet hose of the compressor cover (1) for
air leakage.
2.
Check the suction side of the inlet hose for loose
connections or cracks.
(1) Compressor cover
NOTE
• If you
find an air leakage, change the clamps
and / or the inlet hose.
