my VDO come and go, and there is a fix by cleaning
the ribbon cables
, I think it's linked in the thread.
Unfortunately the fix isn't permanent because the system isn't well sealed. Every time it rains my readout fails, I think it just gets wet. Once it's been dry for a couple days or the engines are run enough to warm and dry the contacts the readout comes back on. I have it on my list to try to solve the sealing issue and if I do I'll publish it but given that I have higher priority chores...
