Connector issue I assume? I had to change mine as they were corroded and it fixed the issue. Sadly many shops don't know how to interprete the fault codes (or lack of them).

Had the same issue on a mk1 fabia 1.4 . Problem was the connectors attatching to the power steering unit, they were corroded. Got new connectors from dealer which solved the issue. The whole wiring loom was also corroded so new cables were made by myself. No shop could identify the problem despite using code reader, their suggestion was simply to "change the pump". I had to fix this issue myself

My dad has experianced this issue with his key. I haven't experianced this issue using my key. I appears that stroking the key a few times against a down jacket so it becomes static solve the issue. I can't explain it though. Why would the immobilizer unlock itself suddenly by making the key static? I recall my dad has partially solved this issue in the past by cleaning the key with a cotton rag, some times it works, some times it doesn't. I litterarly tried to start the fabia today using my dads key and I got the immobilizer icon flashing on the dashboard. I took the key and stroked it a few times against my jacket and the car started up several times after than with no icon flashing. Also when I think about it, the central door lock doesn't work either maybe these two issues are related.
