The product is a genuine BMW alternator designed for the 2016 BMW 1 Series with a 1.5 116D engine. It has a pulley included and a manufacturer part number of W4190A. The alternator is a 12V, 180A with a B+ (M8) connection and a Ø 49,0 mm diameter, specifically made for the BMW 1 Series. This high-quality alternator is a perfect replacement part for maintaining the electrical system of the vehicle. As you can see by receipt I paid £224 but never used it as some1 bought the car SAS. Also there is the tension pulley assembly. I'll sell it all together.
