- Insert exhaust flap manifold - 3 - with the retaining tab - C - in the notch - A -.

Installation Position of the Clamp Between the Exhaust Flap Control Module (J883) and NOx Reservoir or Reduction Catalytic Converter.





- Install new clamp so the clamping bolt is opposite the exhaust flap control module housing and the - 45° ± 10° - angle is maintained.

Clamping Sleeve Location





- When installing clamping sleeve, ensure that the bolt end - arrow - does not project beyond the lower edge of clamping sleeve:

• Threaded connection points toward the right.

• Tighten threaded connections equally to 23 Nm.
