Anyone know what the noise is which seems to be coming from the drivers side of my engine? I have a 2004 Freelander sport TD4 with 67000 miles on the clock. The noise only seems to appear when i take my foot off the accelerator and the car is slowing and i get a kind of brrrrrrrr noise which goes away if i accelerate again. I can not seem to duplicate the noise when stood still and listening to the engine so really stuck to what it can be?? Any help would be really appreciated??
