om605

[datty]

just wondered if there is any om605 guru's on here.got an issue with mine that when it reaches 50-60c doing 40 ish mph it hunts slightly.only 100-200rpm but it its on cruise control its annoying.doesnt seem to do it hot or cold just in the middle.seems when it does it ,does seem to produce more blackish smoke like its going down a cyl and holding back?replaced the fuel filter and clear fuel lines incase its getting air in the system but still the same.any ideas please?

Try knocking it down a gear, my S211 E320CDI does this occasionally in cold weather and that usually stops it. I don't get any noticable smoke though.

Tyres all the same size ? , only suggesting this as you mention when it’s on cruise control

tyres are all the same .just more noticable when on cruise control.fine when cold then it just holds back and look down at temp gauge its about 60c..sort of gets better when warmer then 80c comes and it clears
