Some good news and bad news.Hows it going?
So the plot thickens.Hows it going?
Cheers.Intercooler and inlet manifold are the only other places where boost pressure can escape.
Yeah, I just forgot to tighten the top clamp before I test drove it. Tightened it and it was working as it normally does.If your short hose blew off, are you sure you correctly sealed and fully tightened it, and that it hasn't slipped and air is getting out from that? There is only a small lip on the inlet and the clamp needs to make sure the pipe is tightly held in place and cant slip or leak. You can feel around it and just about see it from the top of the engine bay.
The a large majority of the oil in the boost system is introduced by the breather, which enters the air stream before the turbo. Sudden amounts of smoke would be a concern, but normal crankcase oil mist won't produce any perceptible smoke.I dont think the amount of oil in your hoses is a concern by the way. Mine have always had oil in them, I take the intercooler inlet hose off to get to the oil filter for changing and there's always a consistent level of oil in there. My turbo im not concerned about. Someone else may say different, but mines been the same for the 4+ years I been changing oil in it every 5-6000k miles.

It won't be the cross pipe, as that's not under boost pressure, just normal atmospheric pressure.No update at present.
Took the bumper off again this morning to check the intercooler.
Nothing looked amiss but i was only able to check the underside of it.
I’m wondering if it could be the intake pipe that goes over the top of the engine? The little bagpipe looking pipe? Will spray some soapy water on it later to see.
Was wondering if it was where the discrepancy from the MAP and MAF sensors could be coming from though? If the air escapes after the MAF but before the turbo and MAP would that not cause the underboost as well?It won't be the cross pipe, as that's not under boost pressure, just normal atmospheric pressure.
You can check the pipe between the air filter and turbo inlet pipe for cracks on the convoluted section, which does happen. From memory it gives a code for insufficient MAF signal or something along those line.Was wondering if it was where the discrepancy from the MAP and MAF sensors could be coming from though?

As before, I swear I can hear a large amount of air escaping from somewhere but it's hard to pinpoint it.
I was close to buying a new intercooler just so I know that isn't the problem but don't want to keep throwing money at it
Finally have had enough of this turbo issue so have booked it in to the garage for a rebuild - they're claiming it's the turbo and at this rate, I can't be bothered wasting more time on it.You can check the pipe between the air filter and turbo inlet pipe for cracks on the convoluted section, which does happen.

I see your logic though, so definitely worth a check.
Nothing yet. Still with the garage. I imagine I'll get it back tomorrow or Tuesday, hopefully.What was the outcome?
Called this morning and they've just called back.What was the outcome?
