3804944 Turbocharger Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a turbocharger, in the Inlet and Exhaust System group. It is the refundable charge raised against the old turbocharger when the exchange unit is bought, and it comes back once the worn turbocharger is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3801944, which is the number to quote for the component itself. It is listed for 3 applications across the TAD series. The other turbocharger cores in this block are 3804939, 3804940, 3804949 and 3804950; this is the only one of them carrying a published application list, so the fitment is what separates it from the rest.

⚙️ Key Features

• Core deposit line, not a turbocharger you can fit
• Belongs with the exchange unit, part number 3801944
• Refunded when the old turbocharger is returned
• Listed for 3 applications across the TAD series
• Inlet and Exhaust System group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the turbocharger itself uses exhaust energy to drive a compressor that forces extra air into the engine, raising the power it makes for its size.

⚠️ 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
• Whistling or siren-like note from the turbo that rises and falls with engine speed
• Boost down, with the engine smoky and short of power under load
• Oil weeping from the housings, or oil found standing in the charge pipework
• Blue smoke on start-up or when the throttle is opened after a period of idling

🛠️ Service Notes

• The charge is refunded when the worn turbocharger is returned, so keep the old unit and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3801944
• Cure what killed the old one before the exchange unit goes on, since a choked air filter, a restricted oil feed or a blocked drain will finish the replacement the same way

📦 Condition

• Refundable core deposit - not a physical part
