Battery earth cable to body could be suspect. As you have a pre 2011 model, only a single earth lead was fitted as standard. Search on here for the mod to fit a second earth lead direct to starter motor bolt. 10MY (Sept 09) TD4 HSE Auto in Stornoway Grey (Now Gone)

I posted a video on youtube, it's more just so you can hear the noise.

Bearing is my first thought, or Alternator Clutch |

It doesn't make any noise when driving, only on idle with electrical load, which steers me towards a sloppy bearing.

Hi Blitzer , did a new belt tensioner sort you out or have you had to have further parts , specifically the alternator clutch pulley?

Take the belt off again and turn the alternator pulley in both directions. If you can feel the alternator turning in both directions it is the alternator clutch at fault as you shouldn't be able to turn the alternator (just the pulley) in reverse if the clutch is ok. You'll probably need a special splined socket to get the pulley off. |
