TEST1 Exhaust system check
Engine stopped: Check that the silencer outlet is
not blocked. Repair or replace the silencer, if
necessary.
Check the seal of the exhaust manifold on the
contact surface between the turbocharger and the
exhaust manifold.
Is the seal in order?
YES
Loosen the catalytic pre-converter on the
turbocharger side. Place a wooden block between
the two parts.
Start the vehicle and check if the engine runs better.
Is the engine running normally?
YES
NORepair or replace the faulty part.
NOThe exhaust pipe is not the cause of the
fault. Continue with the engine fault finding
(see ALP5).

TEST1
CONTINUED
Retighten the catalytic pre-converter.
Loosen the catalytic converter on the catalytic pre-
converter side. Place a wooden block between the
two parts.
Start the vehicle and check if the engine runs better.
Is the engine running normally?
YES
Retighten the catalytic converter.
Loosen or disconnect the intermediate chamber on
the catalytic converter side. Place a wooden block
between the two parts, if necessary.
Start the vehicle and check if the engine runs better.
Is the engine running normally?
YES
Retighten the intermediate chamber.
Loosen or disconnect the silencer on the
intermediate chamber side. Place a wooden block
between the two parts, if necessary.
Start the vehicle and check if the engine runs better.
Is the engine running normally?
YES
Replace the silencer.
END OF TEST1.
