[shaahid]

Hello again am having trouble with my e270 w211, i have noticed that the car is puffing out black smoke when accelerating can also feel a slight loss in power also there is a noise of air being sucked in when accelerating any ideas what it could be? Thanks

Most likely a split boost hose or intercooler - check the hoses you can see for any splits.
