Black Smoke!!!!

[p9lad]

Hi Guys,

Bit worried but yesterday i noticed when i accelerated there was a little bit of black smoke coming out of my exhaust. Not huge amounts but a little bit. Im worried i have cracked a pipe or something.

Someone suggested that i fill up the car with BP ultimate and go up the motorway to clean the engine out. but apart from that any suggestions?

I have a Audi 2.0TDI i only do anout 10 miles a day and hardly any motorway driving.

cheers guys!

Mine does it mate, its a diesel, ive seen skodas and mercs leave a cloud behind them!

Every single diesel I have ever been behind has fired out black smoke under acceleration - BMW, Jag, Audi, Merc. I'd not worry.

Its a diesel, it smokes!!! In fact the only diesel that Ive seen that doesn't smoke, is my old 335D

.....or a diesel equipped with a DPF - they don't smoke either, but ALL others do

but ALL others do

and some quite profusely, I follow some right old smokers sometimes, and its like a smokescreen.

As said above - its a diesel and it will smoke. Mine is on the motorway every other day and it still smokes under acceleration. Just looking at the rear bumper proves it.

If you really want to see it smoke though. Warm the engine up to running temperature, then if you can, leave it in 3rd or 4th and take it all the way to the red line. As you do so little mileage, doing this occasionally will clear the soot out of the system out a bit.

Bear in mind that if you do it in 4th, you will be exceeding the speed limit (motorway) before you hit the red line.
