# 3801886 Control Unit Reman | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured control unit from the Ignition and Control Systems group, weighing 2.145 kg and listed for 14 applications across the TAD, D and TWD series. It is the heaviest of the six near-identical remanufactured control units in this range and within 5 grams of 3801881, so use the number on the old unit rather than weight. This unit is supplied on an exchange basis: core deposit 3804886 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
