Not this chestnut again
DO NOT listen to everyone who says its the turbo. As per the link to the last thread its a costly mistake as i found out to listen to all the experts.
some make the noise and some dont
i even rang CR turbos and he thought it was quite amusing as he gets loads of income from this. He said usually there is nothing wrong with most of the turbos sent in for refurb

Just thought i'd update this.....
18 months on and its still making the noise but working perfectly fine
So for anyone who stumbles on this with the same noisy turbo problem..... don't jump to the conclusion that your turbo is on its way out!
I'm getting limp mode quite a lot with over boost codes. What's recommended?
Does anyone get a noise when you come of accelerating and just drive at a steady 1400-1750 revs which goes as soon as you accelerate again?
same as me... get a hybrid and remap = 200+ bhp and cheaper than an OEM
I'd watch out with stock components mate!
A mate of mine has just had a Leon 2.0tdi 170 mapped to something around the 210-220 mark apparently without doing any research whatsoever beforehand! The map was done by some random guy..... Judging by the way my mate drives, I think he'll be in the garage with a goosed car before long!

Mines got the siren noise, quite prominent too.. Turbo was replaced, 18 months ago, 42k miles, has made the noise since I remember. I've got no dpf so figured that might emphasise the noise. Pulls great though so I'm not worried by it.
I'm in it now, just driven 20miles and it does it in neutral. Like you say, rev it, hold it, let revs drip and siren noise comes in. It
was replaced about 2 months before I bought the car, unknown reason?.
There's a vid of mine. It doesn't sound as loud in the vid as it does in reality, but you get the picture.
Haha. I did wonder if anyone would mention the guls. Is yours standard or did you have a remap mate? I'm wondering whether to upgrade the turbo since mines on 178 bhp now.That's how mine sounded before I got mine reconditioned. Just moving the car out of parking space was getting siren sound. It's the lower deeper sound under 2000 rpm that I was worried about! (Must admit never heard turbos making a seagull noise before!)
My original turbo was on the 19k / car tells you it needs a service rubbish. 19k oil changes with diesel no wonder the turbo packed up. VW GROUP screwed up with this!
Now gets serviced once a year or 6000 miles for oil service.
My garage used Midland turbo & replaced oil feed pipe & oil / filter. Only get higher pitched whistle boost after 2000 rpm now. Much quieter & let car idle for a minute after driving to cool turbo bearing down.

Mines the 170 bhp tdi PD in standard tune. Used to be remapped (probably around 200 bhp) but think original software was reinstalled with injector replacement recall at Audi. I'm only assuming but think they might have had to do diagnostic checks when they replaced injectors. Came back feeling slower & this was on the original turbo before it started giving problems.
Turbo on mine had a worn shaft bearing. Play in bearing eventually allows impeller to catch side of internal casing either chipping impeller or unbalancing it. Noise can increase due to this wear or unbalance.
If yours is remapped it could be why you are getting more turbo noise? You need to increase boost & fuelling I would think to make more power?
If you can put up with the noise... stick with it but nurse it along. Keep revs low until engine fully warmed up & idle for a minute after driving.
For info.....Main symptom that my turbo was shot was oil the car used. Smoked badly on start up & I had to put about a litre a month in engine. Since turbo swap don't use hardly any.....probably about 1/2 litre between yearly services.
What's your oil usage like?
Yep that's what I was fearful of.....small bits of titanium impeller or turbo casing in my engine. Got it swapped asap.
One thing to bear in mind if upping performance is the anchors (brakes)! 140 bhp only have 288mm discs on front whereas 170 bhp have 312mm front discs.
Another is the clutch & dual mass flywheel. They are evenly matched to performance & can start to slip if you get too silly!
If you've already got it at 178bhp it's something to bear in mind if going any further. To be honest mine ate tyres when it was mapped! You could still wheel spin it in 3rd accelerating up hills.
