I have a recurring issue on my 1.0 mpi, it all started when the car just randomly cut out one day after the airbag light came on then the eml then it cut out, that turned out to be a dead alternator and dud battery so I replaced them.
However I now had a o2 bank 1 sensor fault so I replaced that which was an epic mission to find an even remotely close one and for good measure replaced the engine temp sensor and thermostat. It still has the o2 fault😭, running it on live data shows it going from closed loop to open loop intermittently then open loop fault. I'm all out of ideas now and I don't wanna have to bin the car as I've spent a small fortune on it mechanically since owning. Help😭
