# 3805100 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 one is returned. Nothing ships against this line on its own; it is an accounting entry that sits beside the unit on the order. Under Volvo Penta's core numbering the unit it belongs to takes part number 3802100, which is the number to quote for the turbocharger itself. That number is not in our own listings, so we hold no stock against it and it has to be ordered in.Eighteen of the 60 turbocharger cores in this run are in the same position, and with no note, variant or fitment published against any of them there is nothing to tell one from another on paper, so order strictly by the number that matches the unit coming off.

## ⚙️ Key Features

-   Core deposit line, not a turbocharger you can fit
-   Paired exchange unit is part number 3802100
-   Refunded when the old turbocharger is returned
-   Counterpart 3802100 is not in our own listings, so no stock is held against it

## 🔌 Function

As a line item it carries the refundable core charge on the exchange; the turbocharger itself uses the energy left in the exhaust to drive a compressor, forcing more air into the cylinders so the engine can burn more fuel and make more power.

## ⚠️ 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 a marked drop in power, with the engine slow to pick up under load
-   A rising siren-like whistle, or a whine that changes pitch as the load comes on
-   Blue smoke from the exhaust, heaviest on start-up and when coming off idle
-   Play felt at the shaft once the ducting is off, or rub marks where a wheel has touched its housing

## 🛠️ 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 3802100
-   Before condemning the turbocharger, check the air filter, the charge pipework and the hose clamps for leaks, and prove the wastegate actuator still moves freely
