Engine management light has come on. Noticed last few weeks car doesn't want to start early mornings, never been an issue before. When running it seems to run rich, strong smell of diesel from rear of car. Ecu fault code was intermittent flap valve fault? We are assuming this is the flap in the throttle body? I've taken the intake off cleaned everything out. When i exposed the throttle body i noticed the flap was in the open position, is that right? I always thought they opened with acceleration to allow more air intake? Recently had new egr valve, cooler and solenoid. Once the car is warm it will start first time all day long until the next morning. When it does finally start there is a load of smoke from exhaust for first couple of seconds?
Any ideas what's going on guys? Cheers
