Hi, I have still not solved the problem. Could still do with help. Thanks Col.
Hi, Thanks for the reply. My local garage has taken my coupe to Hyundai dealer today for diagnostic test, cant wait for the bill!!!!
Let you know more when I do.
Hi, Hyundai said its not ECU problem, it is the BCM tha'ts faulty, not paying them £1200 to replace and fix it. Had car towed out of there yesterday, back to my mates garage.
