Motorists in West Yorkshire were left scratching their heads when a ticket machine at the Ian Clough car park, in Baildon, refused to accept their coins.
Subsequently, many car owners returned to their vehicles to find a parking fine slapped on their windscreens.
Bradford Council eventually visited the offending machine and slapped 'out of order' stickers across its façade to ensure no further motorists suffered the same, penalised fate while the problem was investigated.
One eagle-eyed motorist soon discovered the ticket machine was actually French and configured only to accept Euros.
Two ward councillors Debbie Davies and Roger L'Amie were among those who had tried to use the machine at the car park.
"The pound coin simply would not fit in the slot,' Ms Davies told the Daily Mail. "There wasn't anything blocking it, it didn't go in and then fell out, the machine just couldn't take the pound."
Engineers have been sent in and the machine has now been calibrated to accept pound coins.
Councillor Davies added: "After some 12 weeks of standing there doing nothing - the 'out of order' signs have been removed and for the first time it's operational.
Michaela Hall, assistant parking services co-ordinator for Bradford Council, said: "The parking machines are configured for UK coins and our technician activated the new ticket machine."
