Indicator Relay?

[Cobstar]

Help - the indicators on my RS2 have packed up. We've checked the fuse and it's OK, so assume (perhaps wrongly!) that it might be the relay - based on experience with non-VAG cars.

Trouble is according to the info on the fusebox lid in the engine bay and on the relay panel under the dash don't appear to show a relay for indicators. Local Audi Dealers say there is a relay and one of them ordered one in for me but I haven't a clue where it goes and the number doesn't match any of the relays we can see. (It wouldn't surprise me to find we've been sold the wrong part give problems local garage has had get parts from Audi for the RS2!)

Can anyone help solve the problem - people don't seem to understand hand signals (legal highway code ones!).
