Since fitting my brake pipes, I've noticed the turbo is now quite audible on the move. I'm sure it's pure co-incidence as the brake lines are nothing to do with the turbo and its pipe work.
Whilst driving to the MoT station, I noticed it. Also, under load, say on a hil, there is a more pronounce knock. Almost like the standard noise a Diesel engine makes, but noticeable. Once on the move, it's normal.

I'm just wondering if I've disturbed anything when I took the inner wheel arches out to access the brake pipes. Anyone know what the likely source of the whistle is?

Thanks

Check the hoses are all securely attached. It might be that one has a split in it, the fact it's happened after other work could just be a coincidence.

I'm hoping that's all it is.
Anyone got an exploded diagram of the pipework to and from the turbo?

Anyone?

Ok second question- what should the boost pressure be? I've just checked with the IID tool and its showing around 94KPa at idle, rising to around 135 under load.
