Hi all,
I have a question about my nissan qashqai 2010 with 1.5 dci diesel engine. It is producing smoke, occasionally, every 5,6 days. Smoke is blueish but engine don't burn any oil. In the period when smoke appears, I noticed some sound that is similar with bad injector sound. Also, my rpm are increasing from 750 to 800rpm. Also, my fuel consumption is increased.
My mechanic sad to me that this engine have fifth injector that is connected to dpf filter where it inject fuel to increase temperature of combustion in dpf filter and improve cleaning proces. But, i didn't find any info about this for this model. No errors on the computer.
Is it problem that there is some injectors problem?
