Hi all,
Its ongoing issue with my friend's car's M57 engine, and the issue started with the belt tensioner making noise when the lights were switched on. A small ticking noise is coming from it, and we have taken the most common way of fixing it by throwing money at it. The water pump was replaced, the belt tensioner was replaced the alternator was replaced. By all this, the result was that charging got better, and we had fewer places to put the blame. Noise now sounds like a chain is stretched. If you remove the belt noise stops. So today we removed the plus cable from the generator and were surprised that the noise stoped but if you just remove the small connector, the noise stays and gets worse when the lights are switched on. So my question here is, have any of you run into something like this.
