The car start without problemwhen it is cold, but after driving 15 - 20 minutes it will not start again. When key is turned it tiries to start an turns the engine 2,3, times and then dies. When it is cold again it starts without problem. This situation has lasted for a long time. This problem do not throw any fautcode on STAR eighter. It seemes to loose steering power to the starter relay in the fusebox on the right side in the engine room. Possible ECU problem?
