Hi everyone, I have recently bought a 2004 accord cdti.
It has a very low power problem.
In 1st gear there seems to be no turbo boost at all, 2nd gear boosts at 3500rpm,3rd gear boosts at 3000rpm,4th gear boosts at 2500rpm and so on.
So far I have cleaned the egr valve and throttle body, tested egr valve and the piston opened with 12v applied, cleaned maf and map sensors, it's fully serviced including Bosch fuel filter, used vacuum on the turbo actuator and it moves easily also lubricated it.
I removed the egr pipe at the front of the engine, it was clean, went for a short drive with the pipe removed and the car was a lot better in power off the turbo, first gear was almost normal and was no longer dangerously underpowered when pulling away from a standstill.
The car with the pipe removed revs freely as it should, once the pipe is connected again the revs are a lot slower to rise.
I'm thinking it's really struggling for air.
Has anyone on here have any advice as to what the problem could be ?
It's like the manifold is severely blocked up but it shouldn't be as everything else connected to it was quite clean.
