When accelerating, Large black clouds of smoke from the Exhaust in 1st and 2nd gears cruising there's no black smoke Doesn't use excessive oil Ave 38 miles to the gallon What could c

SOURCE: black smoke from exhaust

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.

Hope that helps!

it has a problem with the second gear drum it cracks and does not fully engauge the n shifts to 3rd ..many honda owners also learn the 8 bucks a quart is the only fluid to pour in a honda..but remember 3 qaurts per drain and fill the tranny holds 7q ....it will take a case to do a drain flush...a high pressure flush will ruin a automatic tranny with alot of miles or metal deposits floating around inside..DRAIN AND FILL 3 QUARTS AT A TIME NO GASKET NEEDED ITS BUILT AND DESIGNED LIKE A MANUAL TRANNY

SOURCE: Sooty exhaust and excessive oil consumption?

2006 C4S Tip, 26,000 miles Now in Porsche dealership having the engine stripped. They are suggesting that one of the pistons is starting to fail. Their diagnostic equipment shows no fault codes but further testing has shown that one bank is having to work harder than the other side. Their prognosis is a new engine. Do not let your warranty expire!!! Also see here: http://www.pistonheads.com/gassing/topic.asp?h=0&f=48&t=731645&mid=154532&i=0&nmt=OPC - Does this sound odd to you?&mid=154532

SOURCE: 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.
