V8 Vantage 07 LED Indicators

[EvolutionChris]

HI All, I was out yesterday and I got a warning on the dashboard saying the indicator bulb had failed. On inspection, the LED was lit but dimly and faintly flashing. I kept the car running, turned on the main beam and kept the hazard lights running to see if I could warm up and remove the condensation from the lens.After a while it started flashing normally, but now seems to work on and off (no puns about that is what Indicators are meant to do!). From reading through the forums, it appears the PCB may be faulty so I have called IER and spoke to Matt as per the forum advice.
Before I remove the light unit and send it down to them for repair, are there any other suggestions of what else this could be?
