could be worn or dirty nozzles. you could try a couple doses of the Motul Diesel System Clean - LINK

and/or a LM Diesel Purge. i recommend doing this just after you pull your next oil sample (assuming your using an oil sampling pump) and just before your change the oil.

if that doesn't clear it up there are other potential causes - but IMHO that's the "low hanging fruit".

cheers!
