3804908 Turbocharger Core | Genuine Volvo Penta Part

🔧 Product Description

Nothing is despatched against this number. It is the refundable core charge that goes on the invoice alongside an exchange turbocharger, standing in for the worn turbocharger until that unit comes back. Volvo Penta numbers a core deposit 3000 above the unit it belongs to, which puts this one against 3801908. We do not list 3801908 ourselves, so order it through the supplier of the exchange turbocharger. Near-identical turbocharger deposits sit alongside it, among them 3804899, 3804910 and 3804911, and nothing in our records separates one from another, so order by the number of the turbocharger being exchanged. The sum is released back when the used unit arrives with us.

⚙️ Key Features

• Refundable core charge, not a part that ships
• Sits against unit 3801908, which we do not list
• Raised against the old turbocharger on an exchange purchase
• Near-identical siblings include 3804899 and 3804910
• Credited when the old turbocharger is returned

🔌 Function

Carries the refundable core charge on a turbocharger exchange. It buys no hardware; the turbocharger it stands against uses exhaust energy to spin a compressor that raises inlet pressure, letting the engine burn more fuel per stroke.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the turbocharger being exchanged
• Loss of boost and power, with blue or black smoke from the exhaust
• A siren-like whistle, or a rattle or grinding from the turbo housing
• Oil in the inlet pipework or charge cooler, and oil consumption that keeps rising
• Shaft play felt at the wheels, or blade tips rubbing the housings

🛠️ Service Notes

• Ordering this line on its own supplies no turbocharger. It is the deposit that rides alongside the exchange unit, so the turbocharger itself has to be ordered as a separate line.
• The charge is refunded when the old turbocharger comes back to us complete and rebuildable; a unit that has been stripped for parts, broken up or damaged in transit is normally refused for credit.
• Send the old unit back whole with the actuator and any wastegate or nozzle gear still attached, and blank the oil feed and drain for transit.

📦 Condition

• Refundable core deposit - not a physical part
