car starts and drives ok, but the service is light on dash its the word and not the service light as in due for one. this light is on the rev counter side. When the code is cleared it will start and no light will be on the 15 secs later light comes on and on the info system says engine fault. Code read the engine and comes back with this code U1134. Also the stop start button does not respond it is light and when pressed will flash and not go out but will stay on. Would like to know what the code means to start with thanks steve
