FAULT COMPLAINED OF

The Customer complains of one or both of the following faults:

• Noise during engine acceleration or deceleration coming from the engine compartment.
• Juddering/jerks at 1500÷2000 rpm.

TECHNICAL CAUSE

The shape of the air inlet pipe to the turbocharger might generate noise in some cases.

OPERATIONS IN PRODUCTION

Adoption of new air inlet pipe to the turbocharger and injection control unit with dedicated software for the new pipe.

IPLEMENTATION OF MODIFICATION

OPERATIONS IN NETWORK

Network behaviour standards towards the Customer

• Once the customer's claimed fault is confirmed, reassure the Customer that the problem can be solved by replacing the air inlet pipe to the turbocharger and reprogramming the injection control unit.
• After the operation, show the Customer what has been done and make sure he is satisfied.

Service Solution

Once the customer's claimed fault is confirmed, replace the air inlet pipe to the turbocharger, replace the oil vapour recirculation pipe connected to the air inlet pipe to the turbocharger (on cars without heated blow-by only) and reprogramme the power unit control module (PCM) according to the Operating Cycle below.

OPERATION CYCLE

• Replace the air inlet pipe to the turbocharger (1 – Fig.1) with a new one, coming from the Spare Parts Department (2) (refer to Op. 1048A50 of the Service Manual).
• On cars without heated blow-By only replace the oil recirculation pipe (3) connected to the air inlet pipe to the turbocharger (refer to Op. 1080D27 of the Service Manual).

After replacing the air inlet pipe to the turbocharger with the new one, the power unit control module (PCM) must compulsorily be reprogrammed

• Connect Examiner or wiTECH Plus (Examiner Emulator) with release 8.20.21 (or higher) and reprogramme the power unit control module (PCM) using the WEB Flash 10.05.0 (or higher) available from wiTEXEDi.

The vehicle battery must be in full charge conditions or supported by a battery charger/booster battery so as to ensure a rated voltage of 12 V, during reprogramming.
