It's not the belt idler pulley on the engine is it? Those are known noise makers on the H2s when cold and at low rpm.

Finally found the problem already..is the weak battery..after changing to a new battery..everything solved!

But, my luck is not on my side again...when sent to a workshop for the diagnosis, there are no power supply from the connector (diagnosis machine can't detect the H2 ECU)! But the H2 still can be starts up and drive around like normal....any ideas??

Many thanks in advance...
