3801782 Control Unit Reman | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured control unit weighing 3.313 kg and listed for sixteen applications - the D12C-A MP and the D12D MG, MH and MP engines, together with the TWD1240VE, TAD1240GE, TAD1241GE, TAD1242GE, TAD1241VE, TAD1242VE and TAD1241-42VE. It is the only control unit listed here, and Volvo Penta's reman catalogue names it alongside turbocharger 3802116 on the D12D MP listing, so the two are worth quoting together. Reman components are rebuilt to the current bill of material, so the unit leaves the factory at Volvo Penta's latest technical specification. Supplied on exchange, so a core fee is added to the invoice and refunded once the worn unit is returned.

🔌 Function

Reads the engine sensors and drives the injection and control outputs, holding fuelling and timing to the mapped values for that engine.

⚠️ Common Signs of Failure

• Engine will not start or cuts out with no fuel or air fault to be found
• Intermittent loss of communication with the display or diagnostic tool
• Stored fault codes pointing at the unit's own circuits rather than at a sensor
• Warning lamps and instruments dropping out together
• Corrosion or water tracking found in the connector on strip-down

🛠️ Service Notes

• Prove the wiring, earths and connector condition before condemning the unit - a corroded connector reads as a dead control unit
• A replacement control unit will normally need programming to the engine, so plan for dealer involvement
• Core deposit 3804782 carries the exchange fee and is refunded when the old unit goes back
