It isn't my boost gauge. I also revved whilst outside the car and it's definately coming from outside. There was also a very strong smell of petrol which is making me think maybe exhaust side of the turbo? Could a split in the exhaust manifold gasket make this kind of high pitched noise? I read elsewhere that the nuts can come loose too  :undecided:

How old is the DV and what type is it? Colour spring etc

its a forge 007p DV, is only 18 months old... I got it when I had my remap and it has a yellow spring. Has never been a problem, this noise only started after all the heavy snow, I didn't start it for 2 weeks and since then it has been doing it. I did notice a little oily liquid (like a single droplet) where the DV connects to the Charge pipe but that has always been the case...

Vag com shows no related faults (i have a few electrical short to grounds) which makes me think it is exhaust side of the turbo? that is assuming a leak due to a cracked manifold gasket or loose nut would not show any faults on vagcom?

I need to get under it and have a proper look, but seeing as it's in a car park and it's always raining or snowing here I can't face it!

I'd check that oil leak near your DV, oil escaping from the inlet system is usually a good indicator of a leak. The smell of petrol can be a sign of an exhaust side leak, check the bolts that hold the turbo on to the manifold.

I've kept my eye on the DV for the past 10 months or so and everything is tight, the leak is more like a light brown film around the hose end and never seems to increase in amount.

Everytime I think I've found what it could be something else happens! Just done 80 mile motorway trip and the high pitched squeal sounds now like a dentist drill and the 'whoosh' sound when coming off boost is significantly louder?!  :undecided: tearing my hair out abit!

I've come to pick my jacks up from my parents house so should be able to have a good look under there in the next week.... In just praying it isn't my turbo  :sad: I'm gonna put on my Bosch dv to see if the noise goes as a bit of an indicator!

Hate to say this mate but that dentist drill noise usually means knackered turbo! You need to have a proper look at it ASAP before it causes more damage to your engine. Just take your turbo intake pipe off and have a feel of your compressor wheel.

That's what I've been reading  :sad: though i'm gonna remain hopeful, I'm not taking my car out till I get time to check it over properly, gonna make some time Thursday to check the whole system from turbo to inlet manifold and all vac lines, so will report back!

Am I right in thinking it should have little/no movement perpendicular to shaft axis and no more than 0.5 mm parallel to the axis is acceptable?

My AUM makes a noise like that. I checked my turbo a few days ago and there was a bit of damage to im impeller wheel and quite a bit of play.  :sad: I aslo replaced my intercooler and noticed loads of oil and metal filings in the boost pipes.  :sad:

So now im looking at replacing the turbo

I've got a load of K03s parts if your interested in rebuilding it instead of replacing.

Uh Oh.... I had a load of oil in my intercooler too, no metal filings though :undecided: This isn't looking good....
