CAN ANYONE HELP PLEASE I HAVE PUT ARCHOIL INJECTOR CLEANER IN AND ARCHOIL TURBO CLEANER IN STILL SAME

[insanitybeard]

Can you confirm your vehicle details? You've posted this in the Mk3 Galaxy section but your profile says you've got a Mk2, and the Mk2's never had 2 litre TDCI engines.

mk3 2.0tdci changed it now

[insanitybeard]

I'm not au fait with the fault code descriptions relating to the number you quoted (P2263) but a quick search suggested it relates to turbo boost control issues, which could range from split boost pipes to a dodgy turbo control actuator (the black electrical box fitted onto the turbo itself, if it has an electrically actuated turbo fitted) to sticking vanes if it has a variable geometry turbo fitted.

P.S, I've no direct experience of this.

[julieade]

could it be the big pipe going to intercooler

[insanitybeard]

If the pipe is split or not sealing properly then yes, there's a good chance it could be that, though split boost pipes usually cause general loss of power and maybe black smoke when accelerating, not so much rough running or a misfiring sensation.

[julieade]

someone said might be egr blocked any idea how to get to it please

[insanitybeard]

Can't help you there as I've never worked on the 2 litre TDCI engine. The valve usually sits in the vicinity of the cylinder head and manifolds depending on how it's plumbed in.

Give it a good revving up, that usually clears things out

[johnnyroper]

I would hazard a guess and say car is either fixed or sold on as it was 4 years ago the OP posted.
