Intake Manifold: Service and Repair
Special tools, testers and auxiliary items required
‹› Torque Wrench (5-50 Nm) (V.A.G 1331)
‹› Puller for Ignition Coil (T10095 A)
‹› Read the safety precautions before beginning work. Refer to => [ Safety Precautions ] See: Powertrain Management/Fuel Delivery and Air
Induction/Service Precautions/Safety Precautions.
‹› Observe the rules for cleanliness. Refer to => [ Clean Working Conditions ] See: Powertrain Management/Fuel Delivery and Air Induction/Service
Precautions/Clean Working Conditions.
‹› Intake manifold overview. Refer to => [ Intake Manifold Overview ] See: Intake Manifold Overview.
‹› All cable ties which are opened or cut off when removing, must be replaced in the same position when installing.
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
‹› Route lines of all types (for example, fuel, hydraulic, Evaporative Emission (EVAP), coolant, refrigerant, brake fluid and vacuum)
and electrical wiring so that the original path is followed.
‹› To prevent damage to the lines, make sure there is sufficient clearance to all moving or hot components.
Disconnect battery Ground (GND) cable with the ignition turned off.
