It isn't normal buddy , worth a visit to an MB independent specialist rather than the garage that didn’t find anything wrong .
Update your details as to your location so members can recommend a nearby Specialist

Hi Matey,

Thank you, and my gut feeling is it should be like that!

I've updated my profile I think?
Cheers Dan

It may be regeneration of the dpf, in which case it’s normal. Is there a colour to the smoke?

Thats is what the garage said how ever just doesn't seem normal, its a light cloudy smoke ill try and add a recording. No won't let me!

Basically it chuffs a fer bit of lightly white smoke for a good while then clears would you think a DPF clean would benefit?
