Exhaust System Components, Removing And Installing

WARNING: Observe the following for all installations, especially in engine compartment due to lack of room:
- Route lines of all types (e.g. for fuel, hydraulic, EVAP canister system, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed.
- Watch for sufficient clearance to all moving or hot components.
- Shift selector lever into position -P- and engage parking brake before working with the engine running.

NOTE:
- Removing and installing exhaust manifold, removing and installing turbocharger with attachments.
- After exhaust system repairs, make sure the exhaust system is not under stress and that it has sufficient clearance from the bodywork. If necessary, loosen double clamps and clamp and align exhaust pipe so that sufficient clearance is maintained to the bodywork and support rings carry uniform loads.
- Do not use any silicone sealant. Traces of silicone components which are sucked into the engine are not burned there, and they damage the oxygen sensor.
- Always replace self-locking nuts.
- Engine Control Module (ECM) is equipped with On Board Diagnostic (OBD).
- Components marked with * are tested via On Board Diagnostic (OBD), Diagnostic mode 3: Check DTC memory.
