primary warning light restricted performance intermittant  sometimes engine managment light no restricted performance intermittant diagnostics point towards turbo boost solenoid any ideas

hi

do you mean turbo boost solenoid, not sure they have one, or do you mean turbo electronic actualtors, which control the boost pressure

these can fail or the actuator mechanism stick dues to carbon build up

do you have a fault code, that will tell you where to look

cheers

Joe

not too sure will get the mechanic to give me  the coding off his diagnostics thanks will speak soon

Still have the same problem have spent a lot of money on problem from so called jaguar experts engine out bits and parts changed other parts cleaned well over £1500 spent on car decided to leave it as it is and drive in all fairnes if I wanted to go anywhere or even Spain it would most likely get me there its just annoying such a nice car has this problem and mechanics dont have a clue as to how to fix it
