306 1.9 TDI Smoking on acceleration

My wife has recently brought an R reg 306 1.9 TDI, and it has started
pumping out black smoke when accelerating, the more acceleration the
more the smoke? and oil consumption, not surprisingly, has increased.

Has any one got any idea what may be causing this please?

Cheers for now

Andy

 

dirty oilfilter and air filter also replace the diesel filter and give
it a good oil change, then give it a run round the m25 if you live
near it.as that will help i done one on sunday with the same proplem
and i did all that to it and the smoke went away

nice 1, i will give that a go at the weekend (will keep me off the
landy for once) and the wife can take it for a spin

thanks

It often is a good idea to start with a service. Replacing the oil and
all three filters gives it thicker oil that will not get past the
piston rings and valve guides as easily. Changing the air and fuel
filters removes a slight strangle on the supply of fuel and air and it
all burns a lot cleaner.

Once you notice it running a lot smoother you can take it out for a
good thrashing and blow all the accumulated muck out. It's best to do
this at night when there aren't any following cars, unless you are the
kind that doesn't feel embarassed at leaving a smoke screen . Once you
have the engine up to normal running temp accellerate hard keeping it
in as low a gear as possible.

The place that does my MOT says they get some cars that have been
treated gently and produce great black plumes when they do the smoke
test.

 

Ah yes, the Italian tune up. Something I always do on my run to the MOT
station if I'm driving a diesel.

 

If a TD is driven gently round town, thei first time you put your foot down,
you blow all the accumulated crud out of the exhaust. this results in the
thick black smoke.
Certainly on the way to an MOT (and from time to time anyway) it is worth
finding an empty bit of road where you can floor the pedal in second, and
leave it there for 20 seconds or so. You will see the black smoke appear and
then clear. It will be better to drive afterwards too.

 

so give it pedal to metal tretment, and the smoke should go away.

 

The only problem is, i dont see my wife treating it gently in the
first place, she only knows 2 positions on the accelerator, on and
off

But its worth trying changing all filters and oil and see what happens
then ? may even start using less diesel than my Landy too ?

 

You give it a good run.
