Default Problem with Mileage display LCD

My A8 has not had much use this month, and has covered less than 200 miles since mid July.

Using the car today, I have spotted that in the top left corner of the mileage LCD display it looks like something is breaking down. I can see the backlight coming through in the top left, and what seems like a weird spider effect. around the edge outside the display pixel area, below this the display is fine and indicates mileage etc. perfectly normally.

I hope it does not spread, although I guess it will and eventually the whole cluster will need to be replaced.

Anyone seen this before, I wonder how fast it will spread before the LCD becomes useless.

Car is 200 miles short of 180,000 miles if that makes any difference.

The clusters have been known to fail. Not seen one personally, but sounds like it's on its way out. Just need to see how long it lasts.

You may be able to replace just that small 'display' from donor cluster. Cluster is easy to disassemble. You just need someone who can solder.

For instance, replacing center display in cluster is a common procedure:

You may need to pay a few pounds for that...

Well the breaking down LCD is certainly creeping. Used my A8 today for the first time in 2 weeks, and noticed it has spread. I'll attach a picture shortly or whats going on.

Attached to this post is picture of the current state of the LCD, if you look up at the display from a lower angle you can see the creep along the top of the LCD. I guess the only long term solution will be an LCD replacement or cluster.

The problem continues to get worse, the creeping on the second inner most end has worsened dramatically recently and is now heading down towards the hundreds of miles on the trip indicator.
