2001 E220 CDI exhaust tail pipe black smoke on acceleration

Hi, I have a 2001 E220 CDI with 76,000 mileage. There is a problem with exhaust tail pipe smoke on acceleration. I have recently got the injectors overhauled and B-service done. The car still gives out black smoke on acceleration. The car’s pull is OK (no loss of power) and fuel consumption is pretty. Can anyone help to guide me want the possible cause might be? Thank you in advance, Paul.

Black smoke is almost always an indication that the air/ fuel mix (ratio), is too rich. I would try to find out if the just cleaned the injectors or were they replaced. Cleaning injectors and sometimes leave irregularly shaped orifices. Besure the air filter is clean. This can effect mix also.
Good Luck and hope this helps.

When I start my car smoke comes out of tail pipe for a few seconds water all so coming out


Water and vapor (steam) coming from the tail pipe is normal and will stop after a few miles when everything is hot. That is one of the reasons exhausts need replacing as they rot with rust and is more evident on cars that only do low mileage as the exhaust does not get hot enough to boil off the water and it sits in the pipe slowly rusting it away. What you see as smoke is probably steam and is more evident on cold mornings. If the car is not using oil then I wouldn't worry.

The dinging from the dash is the Air bag system check. Check that the bulb in the dash isn't burned out. The stalling and spitting could be clogged converter. Check how much exhaust is coming out of the tail pipe when you rev it. The smoke could just be from a leaking valve cover gasket.
