Hi all, i have a Jag X-Type Diesel 2004, 85K. I See black smoke when i accelerate in 2nd & 3rd gear. 1 - cleaned the EGR valve 2 - changed the air filter (used a performance filter) 3 - there was split in the hose pipe from intercooler to the EGR - replaced that too. However, I still see black smoke - not sure what do to ? Please can some help, it will be really appreciated.
