37 Mpg On 1.8 Tdci 2009 Mk4

Hi all , im getting only about 37 MPG and get some black smoke at 2000 RPM and smoky on start up , i blanked off the EGR thinking it would help but i still get a smoky Mondeo and the smell is bad (like following an old transit van), to me its a air or fuel mix problem , there is slight loss of power daily for a second or 2 when you are driving , Ford previously couldnt find a problem and couldnt fidn the fault , i have had 2 engine malfunction amber lights in the last year with the loss of power but didnt have my OBD2 to read the fault each time , without a fault code not sure of the problem , could this be either a turbo hose problem , i cant see anything wrong with the hose , or could this be the MAF sensor or other

check the turbo intercooler pipe and hoses. These are most likely the culrpits, one of these at least will likely have a tiny split!

I had the same issue on my CMAX (see my signature about replacing an intercooler pipe). I had the same issues, underpowered as well as smoke, EGR helped a little but not as much as I hoped. Replaced the pipe and it was perfect.
