# 3805112 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 3802112, which is the number to quote for the turbocharger itself, and we list that number as an exchange turbocharger.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 3802112
-   Refunded when the old turbocharger is returned
-   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
-   Boost that will not reach its usual reading and falls away as the revs rise
-   A rattle or grinding heard as the turbo spools down after shutdown
-   Chipped or bent compressor blades from something drawn in through the inlet
-   Metal debris found in the inlet ducting or the charge cooler

## 🛠️ Service Notes

-   The deposit comes back once the old turbocharger reaches us, so return it complete with its housings rather than stripping it for bits
-   Ordering this number on its own supplies no part; it goes on the order beside the exchange unit, part number 3802112
-   Prime the exchange unit with clean engine oil before cranking, and let the engine idle before any load goes on it

## 📦 Condition

-   Refundable core deposit - not a physical part
