Hi all, need help. Bought my little Copen last autumn knowing the turbo had gone, it drove around ok obviously lacking power though. Removed the old one and yes it had seized probably due to oil and filter looking years old. This weekend i have fitted the new turbo and it goes really well but now the engine light is on. I disconnected the battery overnight then took the car for a run and the light stayed off until I re-started it and it came on again. The Idle when warmed up is at 2k now also. I know the turbo is working ok but i've not heard it whistle or the blow off releasing pressure. Anyone got a clue??????? I have ordered an obd2 reader but still awaiting delivery.
