3802347 Control Unit Reman | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured control unit from the Ignition and Control Systems group, weighing 2.37 kg, listed for two applications across the TAD and TADH families and superseding part number 3801956. The same old number 3801956 is also superseded by control unit kit 3802342 for D-family engines, so the two answers fork by engine: this one is the TAD and TADH route, 3802342 is the D route. Check the engine designation before ordering. This unit is supplied on an exchange basis: core deposit 3805347 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

• Check the supply, earth and connector pins before condemning the old unit
• Core deposit 3805347 is charged with this unit and refunded when the old one is returned - order both together
