Toyota Auris 2009 Diesel, power loss and black smoke.
I have a Toyota Auris 2009, 1,4 90hk, Diesel.
Lately I am experiencing losing engine power and black smoke comes out behind.
This happens on a regular basis. Especially when I drive up long slopes, but also sometimes on flat roads. I lose engine power and the car is moving slightly forward. Black smoke comes out behind. Then I must gear down in the 1st and 2nd gear to make it come. Sometimes I completely lose engine power and have to stop the car. Put it in free and give gas. Then there is a lot of black smoke coming out and I hear a ticking sound of the engine before it loosens and I get full engine power again.
Then I can drive normal for a week maybe, and the same problem occur again.
My mechanic carried out diagnostic and found a failure with the MAF sensor, so we changed it.
This is what I have done so far:
New MAF sensor OK
New Diesel filter OK
New airfilter OK
The car oil consumption is quite normal OK
Then my mechanic also has carried out a new diagnostic and no issues found
The car has run only 130 000
Any advice what this could be ? Im thinking maybe the EGR valve.
I'm completely new to this forum. Thank you in advance for any feedback. 😃
