So before 4 months ago my Seat Ibiza was working a dream. Never had any trouble with it. Started first time. Serviced on time and no issues revealed. October was the first problem. It was a really windy day and I was up a hill parked and exposed. I left her for a few hours. Came back, started fine. Stopped at a Tesco. Took keys out. THING KEPT RUNNING. I had to stall to stop Needless to say it was a spooky experience. Roadside recovery came... problem didn't happen for him and he didn't run any diagnostics or anything. Car MOT in November - some minors about oil discharge,but no issues found. Late November - car doesn't start. Battery dead. Battery replaced. December - heater system stops blowing hot air out. Heating coil (I think?) Replaced. January - today. Another fails to start. Light not on. I can't see any drainage other than possible from my cigarette lighter charge which I plugged into my car before starting the engine. Radio automatically starts when I turn the key over before an engine start too. Any thoughts on this? Usual "common issue" for a SEAT Ibiza 1.4 TDI 2009 - ECU update issue?
