Grey/Black smoke

[C Canavan]

I have a CLK270 2004 Auto 103,000 mls which has been serviced regularly by Mercedes & just had a B service.
my issue is when I pull away & also as it changes gear I have puffs of Grey/back smoke come from the exhaust

does anyone have any advice please?

Hi is this a diesel or petrol engine. First i would check all fluids in the engine compartment dont forget the brake fluids .

Might need a " Italian tune up "
