Hello,
I am new here. I have got mercedes c320 cdi 2009.
One tuning company (Slovakia) has removed dpf from software in the car. But the issue after one month is:
Car has high fuel consumption.
Exhaust makes "popping" sound.
Transmission shifts at high rpm. Behind 2000 rpm.
I think, this is software error and car is in regeneration progress, isnt it?
I have no hardware or software, so I am not able to post software here. What should I say to the company? Thank for all answers.
Best regards, Michal
