I have a jaguar x-type 2.0d. Sometimes when revving the engine hard, black smoke is blowing out the exhaust quite thickly. I think it might be the turbo. Can anybody shed any light on this for me?

the turbo has variable blades in the exhaust side to direct the exhaust over the turbine at low rpm's. It is worked by an actuator that is vacuum controlled from a module. The blades sometimes stick or the vacuum hose goes hard and cracks ant stops working the actuator The bit between the two round bits.
no smoke is normal unless from an exhaust when cold. Sounds like you have an oil leak, some how the oil is dripping onto the exhaust. No self respecting Jaguar dealer would say this is normal.
It is hard starting my VW 2003 Jetta. It usually take 5 to 10 cranking before it turns over. Then it run normally. It only happens when the car has not been driven for about 6 hours.
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.
Black smoke
is caused by excess fuel that has entered the cylinder area and cannot
be burned completely. Poor fuel mileage is also a common complaint when black
smoke comes out of the tailpipe. Black smoke out the tailpipe is the
least cause for alarm. Excess fuel will usually effect engine
performance, reduce fuel economy, and produce a fuel odor. Some of the causes of excess fuel are a carburetor that
is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a
faulty engine computer or computer sensor. If black smoke is present,
check the engine oil to make sure excess
fuel has not contaminated it. Do not start the engine if a heavy, raw
fuel smell can be detected in the engine oil.
This is almost certainly a split hose - mine was the large hose coming out of the bottom of the EGR valve. Speaking to a parts guy at my local Jaguar dealer, he said that the new part is uprated as Jaguar are aware that this is a problem. The split allows more air in and results in the ECU changing the mixture and over fuelling - Black smoke is an indication of un-burnt Diesel. As well as the black smoke you may also notice a whistle/whine or sucking noise when you accelerate and a lack of power / lumpiness at around 2000rpm.
this is a gas engine?
