## ⚙️ Key Features

-   Connection adapter for the D6 F-generation inlet and exhaust arrangement
-   0.025 kg
-   Listed for 29 applications across the D range
-   Consolidates three earlier numbers - 21623073, 21623069 and 3808942 - all catalogued before as inlet manifold items
-   Also supersedes Volvo part numbers 3588033 and 3808802

## 🔌 Function

Forms the factory transition between the turbocharger, the exhaust pipe and the connection hardware that joins them, presenting the correct sealing face and orientation at the joint.

## ⚠️ Common Signs of Failure

-   Exhaust note sharper or ticking from the turbocharger area
-   Soot trail or black staining spreading from the joint
-   Smell of exhaust in the engine space with the hatch closed
-   Sealing face pitted, scaled or distorted on strip-down
-   Threads or fixings seized and corroded into place

## 🛠️ Service Notes

-   One number now covers what used to be three, so an order placed against 21623073, 21623069 or 3808942 lands here
-   Check the mating faces on the turbocharger and pipe for pitting first - a new adapter cannot seal against a damaged face
