CT failure?

Hello all, I have a VW T5 van 2005. It’s coming up for CT later this year and ever since I’ve had it the indicators don’t have the tick/tock sound and the headlight full beam light on the instrument panel doesn’t come on. Everything else on the panel seems to work and fixing as far as I can find out means sending off the instrument cluster for repair. Would these issues be a major or minor fault on the CT?
