Hi Guys
I'm now well over a year in to trying to fix the faults on my 2005 i-CTDi tourer. I know there are similar threads on this subject but nothing close enough to convince me to spend yet more money on going down a particular route.
The problem started out as an occasional power loss, usually a few minutes after start up after the car had been stood for a day the engine would fail to give power when trying to pull away from a junction.
Things have now progressed (or is it a different problem?) so that now there is no turbo boost until about 2,200rpm, and from about 2,500rpm the boost kicks in and the power comes in. As a result the car is a complete dog to drive - to accelerate from 30mph you need to be in 2nd gear, from 50mph you need to be in 3rd gear, and if you don't have loads of revs in when you let the clutch up to pull away they you won't go anywhere.
When the power finally does come in then all the cars that had to slow down for you disappear in a massive cloud of black smoke - though whether that is a symptom or just a result of having to accelerate at high rpm with your foot flat on the floor is hard to know.
The car has never shown any fault codes. It passes all of the test on the diagnostics.
The following has been tried to date:
Replaced the IMRC solenoid (failed a diagnostics test)
Fuel filter changed
Freed up the turbo actuator arm
Refitted the air inlet cover
Replaced all of the vacuum hoses
Had an "EGR-off" remap and full diagnostics run
Cleaned out the induction system, EGR valve, MAF sensor etc
Turbo has been removed and de-carbonised
Still nothing on fault codes or on diagnostics when they are run
So about £900 spent so far and it's still not working.
Any bright ideas where to look next? The engine is as smooth as anything, but its either not getting enough air or not getting enough fuel - but which of those things it is and what is causing it is a complete mystery.
