Looks like my turbo is playing up.  (CrDi 45k).  The turbo has started whistling loudly so maybe a bearing?

It's booked in to be checked next week so I'll be driving it gently until then . . .

Will give you an update when I find out what the problem is.

[komaterpillar]

Could be a bearing, more likely a turbo mounting flange gasket or exhaust manifold gasket. These gaskets are pressed steel and when they blow out or start to leak they make a whistling or screeching sound, like blowing on the edge of a piece of paper. They also will only make the noise when the turbo is on boost as well.

Could also be a boost leak from a loose hose clamp or pin hole in a hose.

If it is a shaft bearing on its way out, you've got a bit on, because every time you hear that whistle it will be the turbo impeller touch the housing wich will be sending alloy shavings through your engine doubt it's a shaft bearing though because normally when they let go it's in a big way 

Good luck with it

I hope it's minor.

Gee, thanks Kom

From around the 50k mile mark I can hear my turbo whining. It's a neat kinda sound which I can only hear with a window open.

[Doggie 1]

Yes, I could hear it at times on April. Never really worried about it.

[Phil №❶]

Nothing wrong with sounding like a Kenworth, eh 

[Doggie 1]

Nice sound when you give it a bit of a rev. 

[2i30s]

the pipe from the airbox could have a split in it,or its fallen off.

The Hyundai dealership had it for the day and have had authorization to replace the turbo under warranty.  They aren't 100% sure what the problem is but it looks like a bearing.
Incidentally, the whistle sounds like the normal quiet whistling noise they make but a hell of a lot louder.  (sounds like the police are following)
When they get the parts in I'll get a ring . . .

 

BC, can you tell us a bit about the sort of life the turbo has had with your driving?

Like:
- Do you push the car along?
- Do you cool down the turbo when you stop with an extended idle?
- What engine oil have you used and how often was it changed?

I'd be interested to know.

I don't drive the car hard - usually changing in the 2000 -> 3000 range.  Most of my driving is stop/start with the occasional trip.
I don't cool down the turbo, although I may do it if I was giving it a hiding.
All the servicing has been at the dealer, with oil changes between the major services.
I think the oil is the Hyundai labelled one.

I'm going to try and get a precise reason for the failure after the turbo is off and they've had a look at it.  Will let you know when I find out more info.

Ok, at last I have the car back.  After a bit over 5 weeks of waiting & promises.
They replaced the turbo and think it's a bearing on the way out.
Initially here was a wait of about 10 days for the part.
This was followed by a wait for an authority to carry out the repair - about another 2 weeks. Incidentally, this type of authority is pretty standard for expensive warranty.
Then there was a request for the service history - again pretty standard stuff but more waiting to hear back from Hy Au. 
All this took a total of 4 weeks.  Once approved, the dealer couldn't fit in the repair for a week.
To top things off, the job was expected to take 1/2 a day but turned out to be a lot more involved than anticipated and ended up taking about 1 1/2 days.  It was the first I30 turbo they'd replaced. . . .
The parts value was approx. $2500 & probably another $1000 for labour.

My gut feeling is that most of the delays were due to Hy Au being slack - someone on holidays?

Considering it was well within warranty, been dealer serviced & was effectively off the road, the delay getting this resolved was far from acceptable.  After being very patient, I was just about to ring Hy Au and blow my top when the final ok's came through.  I'll probably still contact them to see what they have to say.
 

[Dazzler]

Yes, you have every right to be annoyed.. Sounds like a lot of that could have been done at the same time.

The Authorisations should have been attended to while the parts were on their way (for example)

I would be "tactfully" venting my anger on Hyundai H/O (Hopefully some free servicing may be forthcoming to compensate you for all the inconvenience) 

A little disappointing re the time taken to actually get started but if it's fixed you will forget about that soon enough. Turbo bearing? I'd be thinking about the oil used of course and whether I'd perhaps flogged it and not given thought to a cool down more than once.

What's a good oil to use?


Only joking! 

What's a good oil to use?

I use Olive oil for almost everything but Bran oil for really hot cooking as it has a very high smoke point.

Is the olive oil you use the really ugly version (extra virgin)?

[elantraelite]

I think I may have exactly the same problem.

I only just noticed the noise properly today. It's more noticeable when the window is down, but you can slighty hear it in the cabin with the windows up as well.

It's almost a constant whistle and as I accelerate it gets louder. It does sound like a police siren.

I going to get it booked in for an inspection as soon as I can.

[bryanj86]

The turbo will make a slight whistle anyway in any car.. it shouldn't be screaming though

[elantraelite]

It sounds like there is a faint siren outside. I dont want to sound paranoid, but ive never noticed it before and have driven it heaps with the windows down.

i bought the car about a month ago with 55000km and now has 59,000km so i guess this is what happens when you dont know if the car has been warmed and cooled down.

[Doggie 1]

On my last i30 (FD) I always cooled down after driving but that also had a faint turbo whistle.
There was nothing wrong with it and I actually quite liked the sound to be honest. 
I think it is normal, providing it isn't excessive.

My turbo also whistle a lot.

When accelerating I can hear the whistle, even with the windows closed, it does sound like a police siren, but it has done that since I bought the car with 126.000 km on the clock, have now done 178.000. The whistle haven't changed at all, so I'm not worried.

[BC]

The whistle I had was very audible with the windows up - you won't have any doubts when it happens. 
It literally could be mistaken for a siren close by.  Also, it started quite suddenly - it didn't gradually get louder.

Yours sounds more like normal turbo noise.

[2i30s]

what dealership carried out the repairs/warranty BC? 

[elantraelite]

The noise mine has you can hear clearly when its idling and you just light tap the accelerator (out of gear) and it makes a sound similar to a vacuum cleaner... ? Not the same?

[Asterix]

Yep.

That was also what I tried to say..

i can't hear mine when idling.

The vacuum cleaner I will have to check out tomorrow..

[Doggie 1]

Gee, that sucks.

Chadstone Hyundai have done all the servicing & are generally pretty good.


Also Elantraelite, my whistle was inaudible when idling and only became obvious when the turbo
started to work a bit with a some load & few revs.
