Instrument Cluster Problem

I have a Fabia 1.4tdi 2009 and every winter I have an issue with the instrument cluster flashing and beeping on a cold start. This only happens when the car is cold, once warmed up the issue goes away. I’ve taken the cluster out and taken to a cluster repair specialist but they couldn’t find any faults (although I did drive to them and problem had gone away by the time I reached them). A few other observations I've noticed when this happens:

• sometimes the clock resets back to 00:00

• as it warms up, the problem changes in that the cluster works fine for 10-15 seconds and then beeps 3 times as if its resetting

• no issues with radio, fan, internal lights, etc when this is happening

• if I have the headlights on the beam light on cluster is not affected (ie. everything else is flashing but that isn't impacted)

Can't upload videos as they are too big so hope you guys can see these video links:

Anyone seen a similar issue? Could it be a problem external to the cluster (eg. a sensor giving a bad reading or something while cold). Also, I’ve seen photos of a few different clusters in these forums and online but never seen the one I have. Is it a cluster that was used for a limited time. Any advice would be appreciated. Everything else on the car runs perfect.
