Odd thing to do. The Queens Arms and the Mt Edgecomb (now closed) pubs are about a block away from each other. Easy walking distance.
Dunno what part the cat played, it was tough reading the small article. Interesting that someone tried for a workers compo claim, seems not much has changed since then!
As for the immobiliser, I don’t know how it works or if they can be tricked as such. I always thought you needed a matching ECU, key transponder and immobiliser magic box to make it all work and that it’s rare for them to have issues. But from what I can see from adverts for immobiliser sets the ECU isn’t married to the immobiliser unit in the vehicle.
Anyway, it seems you’ve re-sparked the old relay that may be the cause of your previous running issue. I hope it’s still all going well/strong without a hint of an issue lurking!
