Hi guys. I've got a question on polo indicators if anyone can help?!?

I have a 2001 Polo 1.4 SE. The right hand indicators started working
intermittantly, flashing erraticly when they played up. The lhd indicators
worked fine....
I had the indicator stalk replaced when the car went into the dealership
for some work to be done. Since then, the rhd indicators have stopped
working altogether!!! The lhd indicators still work fine....
The dealership say that I now need a new indicator relay. I'm a bit
reluctant to have it changed, as since changing the stalk, the indicators
have gone from erratic to not working anymore!!!
Can anyone shed some light on this or has any experience with this kind
of fault?

Many thanks in advance.
