Fuel Correction and Black Smoke
New to forum and technically illiterate just after some opinions on what to do next.
Have a 2005 XC70 D5 163bhp under heavy acceleration a get a cloud of black smoke out the back. It has done 105000 miles with full service history All airways and pipes have been checked and no problems, egr valve has been replaced, intercooler looks OK and no fault codes when on diagnostics Only issue that shows up is Fuel Correction figures as follows Cyl 1 - 7mm3 Cyl 2 - 5.04mm3 Cyl 3 - 6.03mm3 Cyl 4 - 0.00 mm3 Cyl 5 - 35.67 mm3 No 5 injector was replaced but the values did not change. Then injectors were moved around and value did not change. Has anyone else had this issue and how did they resolve ? My first thought is to replace all 5 injectors (used as new far too expensive) but not sure if this is the answer Running out of money and patience for more guess work !! Can anyone help ? |

I would be getting some peak boost and MAF figures too before focusing solely on injectors.

Hi thanks for the reply. Unfortunately I am not technically minded and have no tools. All diagnostics carried out by my local Volvo specialist show everything runs correctly no codes have been saved. I was just hoping someone had encountered a similar problem and had a solution. I cant afford to experiment any further
