Lots of black smoke when accelerating, but computor saying 44.5mpg around town
Your duplicate question did not say it was a diesel.
Usually black smoke on a diesel is dirty injectors or the engine temp not reaching normal range.

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!

This is usually an indication of a bad head gasket.I gasket. The white smoke is the coolant leaking out of the engine and winding up in the oil passages, due to a bad head gasket. To confirm this,
1. check oil. Is level increased, or milky appearance?
2. Is coolant level dropping, but u don't see any signs of leaks?
The above indicates a bad head gasket, causing the white smoke u describe. Let me know how u make out.

Hi
The only sensible way forward is to get a list of fault codes from the onboard diagnostic system and take it from there. You could either go to a VW dealer, or if you are technically minded you could buy a £15 interface cable, download some free "VAG diagnostic software" and run it on a portable computer.
There are lots of possible reasons for the problem and guessing will not really help. If these suggestions turn out to be sound, please give my reply a "Fixya!"rating, If they do not, please hold off rating and add a comment with more details so I can try to help you further. Cheers, D
