Maybe one of the indicator bulbs are on its way out?
Old bulbs cause excess resistance and cause the indicators to flash fast.
I would swap all the right indicator bulbs with the left ones and see if the problem then happens on the left.
If so, then change the old bulb(s)
[edit] just realised u said they are only 2 weeks old, but its worth a try swapping them around anyway for diagnostic reasons.
