Focus P2263 fault code.... HELP PLEASE!!!
Discussion
Hi,
I have a 55 plate Focus Zetec 1.8 tdci, recently noticed black smoke coming from the exhaust under acceleration with a loss of power, swiftly followed by the engine management reporting a system fault.
The RAC came out and read the code as P2263 - Turbo Charge Boost System
They removed the EGR motor and found that the mechanical part of the EGR valve in the inlet manifold was stuck slightly open but could be operated manually. They also said the black smoke was unburnt fuel. There doesn't appear to be any splits in the pipes, the intercooler pipe was changed last year.
I took it to the garage and after they "diagnosed" it themselves they replaced an air mass meter. This has done nothing at all... charged £160 for that privilege, not happy!
Any ideas what I can do as I feel less inclined to go back to that garage, I'm not mechanically minded... Can follow instruction though! I have been told to blank the EGR but unsure whether this is a good plan.
Am I damaging it by driving it still? It has not put itself in limp mode...yet!
Any help... pleeeeaaaase?
Thanks.

RAC check EGR despite it saying turbo fault, kinda logical, but not the full picture.
Other garage changing MAF despite it saying turbo fault, could have had a dead MAF but that is irrelevant as the fault is still there
Black smoke = running rich.
Running rich and turbo fault to me says turbo isn't making requested boost. The turbo makes boost via a combo of exhaust turbine flow gasses which are a function of EGR, so that being a bit open will scavenge the turbo of gasses.
However, it's a slight amount and you'd still make boost it'd just lag more. Also it was noted it was a slight opening. This could be it if it's not triggered the fault. Can you manually close the EGR and then remove the vacuum feed to the actuator? It might log a fault for that but if the car runs ok (clean etc) then that might have been it.
The next function of boost is intake restriction, so normally it's heavily restricted. If you remove restriction then boost drops. So a boost leak between the turbo compressor and the intake manifold. This certainly could lead to a loss of a lot of boost and no way to attain requested boost, I would imagine that would log a fault and limp mode quite quickly though. Easy to test by removing a boost pipe hehe.
The next function is control, the turbo makes a requested boost based on it's current boost and a requested amount. To vary the boost it makes you control VNT or a wastegate. That controller might not be controlling properly... which is the one I'd go for. Probably just the control solenoid.
Might even be the same type as the EGR so you might be able to swap them around... not sure though just guessing here.
Really easy to check these things and pinpoint the problem with modern diagnostic gear.
The engine will protect itself. You just need to find a *good* garage, not one run by cretins.
