Hi
EGR may be the issue in regards to cleaning but I cannot see it being the copper washers at the base of the injectors as its not chuffing (blow back through copper seal) and no leak or smell of diesel.
But maybe the EGR does want cleaning

Thank you again
Regards
Steve
Thank you Steve.
I will replace washers anyway,as it is not expensive investment.
Regarding EGR,first I will take it to highway to try to clean it up,as the most of my car riding is city.

He told tha washers are probably bad,or well burnt and therefore doesnt have necessary sealing ability.
As the EGR concers,I am almost 99% my driving is eo called city driving and I know it needs some highway.

The EGR probably needs replacing. You can possibly try blanking it as a diagnostic test and see if the hesitation disappears.
