⚙️ 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
