Vacuum pipes
 

Just a quick one. I'm feeling lazy.
Does anyone know the internal diameter of the turbo vacuum pipes.
The one from the vacuum pump to the solenoid and the solenoid to turbo. Got a fault code. Someone had been here before as the engine pads are not connected. They are clearly faulty and need replacement so for now I just want to replace the two I've mentioned above.
Thanks

I've not removed then and measured. They are all 4mm ID
Apart from the one going to the turbo. It is a rigid plastic pipe which seems to be 5mm but the end is deformed due to last owner.
I'm hoping to remove it and replace with my new 4mm ID pipe when it arrives........

I've now replaced from the pump to the turbo solenoid with 4mm ID silicon hose. That's a straight pipe with no T piece or joins.
(I'm not using the engine mounts at present)
The original rigid plastic pipe to the turbo is bodged at the solenoid end by fitting a pipe over it to join.
I wanted to replace but I can't get to the turbo.
I didn't want to pull the pipe off as seems I can't see it I was scared I wouldn't be able to get the new silicon pipe on.
Any one done this. Do I need to remove the turbo?
I have routed the rigid pipe round the side of the engine just above the gearbox. It was going over the engine with the pcv pipe.

The problem I have is under heavy accelerating. Around 3k revs, maybe a bit higher. I lose power. It goes really flat.
I have a code on Vida to say there is a vacuum leak.
Is it possible it could also be the vacuum pump or a faulty turbo solenoid? Does anyone know how to check these.
I am going to buy a vacuum tester so I can check the pipe going to the turbo.

Under normal driving it seems fine.
It's just had a full service done by me.
All filters (except fuel(wrong one supplied)) will be done soon
New oil and just had a coolant change
Thanks

What is the DTC?

Hi, the DTC is..... ECM-6805(boost pressure control.. Faulty flow)
It also has ECM-0000 which is faulty communication which I believe it's probably the same thing?
Thanks

If you have eliminated vacuum leaks, as you can when you have your tester, then the ECM-6805 is most likely caused by coked-up inlet guide vanes in the turbo. Operate the turbo actuator with the vacuum tester and check for full movement. If it only moves a little, it is the IGVs. Remove the turbo, clean it or replace.
Been there, done it.

Thanks, it is ordered and coming direct from the manufacturer.
I'll just have to wait......
The turbo looks like a nightmare to remove... How did you get down there!?

It is just possible to get it out through the top but the official way is to remove the bevel gear and go down.
I gave the job to my local indie. They also replaced the intercooler. Total cost (inc. recon turbo) ~£1100.

When I got it in July last year I cleaned all the EGR cooler and valve.
It was really coked up.
So I imagine the turbo will be too.
I will remove and clean as a matter of course.
Best place to get the gasket set from?

Specialist turbo recon company?
