Take the engine splash guard off from under the engine.
You can do this without vehicle ramps or a hoist.

The big long plastic pipe (the charged air pipe) from the turbo at the rear of the engine down under the engine all the way to the front and up to the intercooler is immediately visible.

It is common for this pipe to crack, causing an air leak, whistling noises, loss of power, excessive soot and DPF filter sooting up quickly.

Replacing the pipe is quite straight forward. Replacing it is much much easier if the vehicle is on ramps or a hoist.

Here's a video showing the pipe.

Hi, I checked the turbo pipe this morning and i couldn't see any splits or movement in the pipe. see photo all brackets as good as this one.

attached to that will be an L shaped resonator box that has an orange seal at each end and goes up to the turbo.

These orange seals often fail and give your symptoms.

If you look at the video that Swiss posted you will see him touch the resonator box at 15m 55 seconds in.

That's where the orange seals are located.

The resonator box was quite solid, no movement, but i'll have another look on Tuesday and post back. thanks for the suggestion. Ian

Give all the intercooler hoses a check to make sure there secured and not worked loose or split and also the intercooler itself hasn’t split.

Thanks, will do on Tuesday Ian

Hi, I had a look today and i can't see any leaks, the top washer on the resonator box is hard to see and i can't imagine how you would remove it. see pictures of the bottom washer and an attempt at the top one. Oh and i forgot to check the intercooler hoses, i'll do that tomorrow. Ian
