My car decided to give out a lovely "WOOOO" tone during acceleration, Turbo shaft appears sturdy intact and no play. there is no smoke and all pipes appear to be intact has anyone else had this issue.

Its clearly turbo as car tries to boost but cant.

Ill upload video would be great if its not a failed turbo and just something I've missed

Can you get someone else to rev her whilst you poke about under the bonnet for boost leaks, etc?

I've had a look can't see anything just all points to turbo :/

[brookie]

don't sound good

Dead turbo. Classic 'siren' sound.

What age is she?

 

[Naomiix]

10 so getting on. I've only had it 6 months! Im pretty stuck what options I have.

 

[marco_polo]

At 10 years old, your £1000 turbo was probably taken out because nobody changed a £30 filter. . Make sure the PCV block breather is changed while it's all apart, or the next turbo will only last a few miles.

Post up the last 7 digits of your VIN number and we'll tell you all about her.

As marco said, that turbo is shafted (excuse the pun)
The m47 did suffer a few turbo failures

 

[Octavius]

How much is a turbo for one of these.
Recon or new ?

 

[Naomiix]

Which filter are you on about? Just so I can querie it on the non-existent service the garage apparently done when I bought the car

 

[marco_polo]

It's the block breather. BMW changed it from a filter known as a 'loo roll' to a vortex type seperator (like a Dyson).

To be fair to your garage, it's not on any service schedule, so even BMW wouldn't have changed it (out of warranty period).

Bomber had kindly done you a nice guide here:

And it's only a working theory, it might just have died of old age, or still might be a boost leak. Double check you definitely have a vortex breather though!

I just a ran a diagnostic and these codes came up:

4530 charge air pressure control, control deviation.
3ff0 Air-mass flow sensor

Could these be linked to my turbo issues? im assuming 4530 indicates a boost leak??

 

[marco_polo]

Low boost, basically. Often caused by a dead turbo, or a boost leak.

Ive found a split in my intake hose - and lots of carbon build up in the intake could this be causing my issue?

 

[Anish1993]

Loool you really don't want it to be the turbo

A boost leak? Nice! You might be in luck yet. If only somebody had have suggested that on Saturday morning! Is it the elbow between intercooler and EGR?

They all get a bit carboned up inside the metal EGR body. Take it off, cut the worst out with a scalpel or similar, then have a go with some oven cleaner.

And whatever you do, don't forget to check which block breather you have fitted!

 

[Naomiix]

Block breather??

how do I check the actuator? how do I locate and check for damage ect?? can find loads about them but nothing specific enough to help me check it!

 

[Naomiix]

and yeah the elbowy bit from intercooler to plastic EGR pipe, scraped it off best I can! now just to source the pipe £244+vat from BMW so that will be a NO

 

[Naomiix]

Loool you really don't want it to be the turbo

Nope! its the last thing I want!

 

[marco_polo]

Block breather??

The filter we discussed at length on the first page.

You can try a few breakers, but helpfully they often saw through the charge pipes while they're yanking engines out!
