Good evening guys
Any thoughts or ideas welcome I have a s 320 cdi w221 year 2007 166km on clock and it’s blowing black smoke which means to little or too much air by my reasoning.
I have put car on star no faults showing
I have tested every thing in cdi engine management.
Compression , injectors , egr,s , maf’s and so on all working perfect . Inlet shut off works perfect .
When you drive the car at 60 km a hour and at 40 km a hour you get a hesitation almost jumping like dirty fuel so I emptyed everything . I filled her up with new fuel and mb fuel filter no change of symptoms.
I have a donor car which runs perfect so I changed the following
Both egr’s
All injectors
New turbo
Cleaned dpf
New o2 sensor
New maf s
Still no change and still no faults on star in any area
I’m at the stage I don’t know what’s happening and any ideas welcome
It’s a strange one
