I have a focus 1.8 tdci 2009...
At slightly faster acceleration ( overtaking or even
accelerate uphill ) engine management light comes on( red exclamation
mark )... or sometimes the orange light for error on ... if I restart the
engine the red engine management light doesn't light any more...while orange light
for engine usually lights for a day...
I noticed that the car after error message has noticeably
more power (before it doesn't have the power that it should have) .
Occasionally when I roll at the intersection or stop at
traffic lights out of gear ...is the engine running sometimes restles... I do not know if
this has something to do with it ....
I had the car at the mechanics and he does not know exactly
what it should be ... because a mistake for air flow meter and possible error for
EGR valve is reported ...
He tried to clean the EGR valve , but he could not open it...
But flap opens well ...
I wonder how to clean the EGR valve ?
Has one of you had similar problems and succeeded to
eliminate them…and where could possibly be a mistake ?
Greetings and Thanks for all the answers!
