BMW N47 Engine - 1, 3 & 5 Series, Plus X1 & X3 Diesel Models - Alternator Replacement
Channel: Kev's Shed
Date: 23/01/2022

Hello everyone and welcome back to Kev's Shed.

In this video I am going to be carrying out a complete replacement of the alternator on my BMW E81 1 Series 123d Coupe. The process is going to be identical on all BMW models with the N47 engine including the E8* 1 Series, E9* 3 Series and E6* 5 Series plus the X1 and X3 models.

The alternator currently fitted has developed a squealing noise which is particularly evident at starting and stopping of the engine but is definitely there at all times when driving and as you can imagine, this is incredibly annoying. 

The noise itself is in the bearings which are obviously worn, but this alternator has been fitted to the car during my entire ownership which has been almost 4 and a half years so it's easily due replacement and I am not upset about having to shell out on the part given the service it has given up to now.
