Black smoke on acceleration diesel x-type jaguar

2005 X-Type 2.0 Diesel. Black smoke produced on heavy acceleration no smoke when travelling at constant speed, fast or slow. Gentle acceleration produces little or no smoke. Black smoke preceded by a breezy/blowing sound. No smoke when idling. An air current can be felt above the cambelt when the engine is revved. Any ideas

    Sorry I'm no mechanic, I don't know what an intercooler is. Trawling through all the threads I can find cracked/split hoses have been mentioned alongside an EGR valve.

    Thanks, I'll have a look tomorrow. Does air blowing out from somewhere in this area when the engine is revved mean there ia an air leak? Thanks Ian.

    Thanks Joe, It was split hose to the intercooler. My mechanic was impressed with my diagnosis. Word of warning though for anyone else, although this is a quick cheap fix, not getting fixed can lead to serious problems and you should drive very carefully, low revs, until fixed. Apparently this hose problem is common and the part is now improved.

    Change of the intercooler solved the issue. It was internally damaged. No more smoke and better response since replacement. rgds

The inter cooler takes in unused fuel cools it and puts it back into the engine . so its black and oily it will be mucky around the crack. have a look with the engine running . you said you could feel air around the cam belt? around that area push and pull hoses and pipes etc . see if you can locate the problem that way. if you do . cean it off well . i did and used 2" wide tape to seal it up . if this helps rate me thanks joe

Black smoke when accelerating

Is it a diesel? Have noticed when following Jags that they all seem to smoke when hard accelerated. If not oil is burning in cylinders, bore wear or valves letting oil into combustion chamber,Get a compression check done.

Black smoke from nearside exhaust, on occasions.

Black smoke indicates it is feeding too much fuel. Maybe problems with the fuel pump.

Diesel engines always put out black smoke, so it is probably normal.

Jag X TYPE Diesel Black smoke coming from exhaust on acceleration

i had this problem and thought the fuel filter oil filter needed replacing so i have just had a service done but problem is still there but not as bad. been told it could be the AGR valve or a split pipe going to it which recuirculates unused fuel back to burn again. therefore unspent fuel is coming out of the exhaust causing the black smoke. i am still looking for the answer aswell, hope this helps.
