Please I need help with the following.
My Toyota Avensis periodically exhaust white smoke, it last for about 2 seconds and stop. It seem like a valve opened and all the smoke rushed out then it closed back. It occurs almost every 7-10 minutes and gets me worried. The emission is sometimes very much that the cars behind tend to move to the other lane but it disappears within seconds.
I have had the engine checked and there seem to be no problem. I am guessing the issue might be with the DPF or Exhaust system.
What do you think please?
PS: There is no alarm
