# 3805186 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 3802186, which is the number to quote for the turbocharger itself; we list that number plainly as a turbocharger, without an exchange or reman suffix. The row carries a listed weight of 5.738 kg. Nothing physically ships against the deposit, so read that as the mass of the turbocharger involved: it is what the old unit will weigh going back, and it is the figure to book the return freight against. That puts the old unit in parcel territory for the return, rather than on a pallet.

## ⚙️ Key Features

-   Core deposit line, not a turbocharger you can fit
-   Paired exchange unit is part number 3802186
-   Refunded when the old turbocharger is returned
-   5.738 kg listed against the row
-   Inlet and Exhaust System group

## 🔌 Function

As a line item it carries the refundable core charge on the exchange; the turbocharger itself recovers energy from the exhaust to pressurise the inlet air, raising the amount of fuel the engine can burn cleanly.

## ⚠️ 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
-   Smoke on every start and a persistent smell of burnt oil around the engine
-   Boost pressure faults logged at the helm that return after the pipework has been proved tight
-   The turbo taking noticeably longer or shorter to spin down than it used to
-   Seals gone at the turbine end, with oil tracking down the exhaust side

## 🛠️ 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 3802186
-   Clean any oil or debris out of the inlet ducting and charge cooler before the exchange unit is run

## 📦 Condition

-   Refundable core deposit - not a physical part
