hi all,

 

i have a 2.0 hdi xsara pic which has always had problems with smoking from the exhaust, usually this is just black smoke/soot pouring out when i floor it but recently i have noticed an almost grey coloured smoke from the exhaust when driving slowly, the engine doesn't use any oil or any water and there is no creaming under the oil cap or any leaks that i can see,

 

any suggestions on what to try next?

White smoke can be caused by hydraulic fluid leakage.  Has your brake fluid level dropped?

not as far as i can see, it still was on max and surprisingly clean for what is pretty old fluid, there's no hissing either to suggest a vaccum leak

They all chuck out smoke- hence the reduced tax rate for diesels !?!

 

Try starting with oil and filters service,

The only diesel I owned that billowed smoke was a Ford Fiesta, got it brand new and it always smoked on acceleration, none of my Citroens did unless there was an EGR problem

i think this is going to be one of those faults, today i covered about 100 miles and lots of hard acceleration yet there was no smoke at all and none of that grey stuff at idle either which confuses me. i can't moan though because it seems to be running very well at the moment

Hi mf1999.  What you did is called an Italian tune up.

Also worth trying a tank or two of Shell Nitro Plus V Power Plus or  B.P Ultimate or Esso Supreme.  It really does what it says on the tin!  It'll give the enginge a good clean out. The cheapest way to clean the engine.

i'll have to give that a try, i usually just fuel it up with either bp or esso as they're about the closest none supermarket fuel station to my house. i'm quite confident that it seems to have stopped smoking now as i can go full throttle in 3rd without even a hint of smoke and nothing at idle either.

Arthur M was right - an Italian tune up. Hammer it.
