I've noticed recently a couple of noises that are giving me cause to worry.

Symptoms:

When pulling away lightly (turbo not even spooling) I am getting what can only be described as a low pitch whistle/whine which rises in pitch with accelerator movement/revs until I get to '0' boost.

From 0-10psi I don't hear anything but the turbo spooling up.

...above 10psi to full boost 19psi I again here the whistle but this time much higher in pitch, rising with increased psi. It is barely noticable but it ISN'T my imagination as even the wife noticed it when prompted. It also isn't the turbo spooling as it has only become apparent in the last 2k or so.

Car has done 30k. Serviced every 10k. No smoke. Boosts amazaing as always and holds boost fine.

Is my turbo dying, is it something else - do I need to worry?

Its going in for a service next week and I'll ask JBS to take a look but I want to be prepared.

Thought it may be the gearbox but it also does it in neutral - rising in pitch with revs.

Anyone?:(

Could still be the gearbox, even in neutral some shafts are turning in the transmission. Does it do it with the clutch depressed.

I'll give it a go when I get home. I don't know whats worse - turbo or gearbox - either way its looking expensive. Had false hopes it was gonna be a split hose or something simple like that:(

i know its a long shot but i had the same problem on my metro turb, and it turned out to be layshaft bearings...

i had something similar but louder and it was a bent vane on my impellor. but mine was very loud and sounded like a thistle whistle :(

Nah this sounds like what I can describe as a police siren(US) but very faint - like someone whistling very low (or high) but very quietly, raising or lowering with revs. It has made absolutley no difference to power delivery or gear change, no smoke - totally foxxing me but also concerning if you catch my drift.

Thx for the suggestions so far.

Ok, I've just run the car with clutch down and its still making the noise so I guess that eliminates the gearbox. On a plus note I've just realised its still under warranty, first reg'd(23/03/04) so I'll take it down to dealers and pray lol. Glad it happened now and not in 2 weeks.

Will be the turbo generally only if you start seeing smoke. If the wine gets louder and louder, particularly if it does it when in neutral when you press the gas, might be turbo.

If smoke starts appearing you've got about 500 miles then it is toast. :thumbdwn:

mine never smoked yet it was and still is knackered, its in my garage still

Well my worst fears were realised - it is indeed the turbo or at the very least boost related. Jbs had a look round and although at first a little bemused (a suggestion was made that it was interference from the stereo lol:rolleyes:) , they eventually diagnosed a 'problem' with the turbo/boost:( - i think liked the radio suggestion better tbh.

As it is still under warranty (yes even WITH the mods - GL authorised them as it was a demo car) I took it up to them to have a look. They don't seem to think it is the turbo but rather a leaking pipe:confused:, either way its booked in with skoda on friday as the warranty runs out next week so it needs sorting one way or the other. I just want to give it some now I have the brakes to make it stop (thanks Gaz-Jbs) but with a possible dodgy turbo I am nervous if I so much as think about pushing my foot down:mad:

How did you pull that off with those mod's:confused:

Helps getting a letter from the manager that the engine mods they put on the car will be covered under there own 3yr warranty - one of the things I bargained for when buying the car in the first place. So glad I did now!

so you didn't do the mods the dealer did? if so then i think its upto them to sort out

Hi I3eman, From what you've said, you're covered even if it takes a few weeks to resolve, cos you raised the issue before the warranty expired.

My thoughts exactly - legal representation will be sought if not.

Yeah it would appear so. I aint gonna relax though until I have picked the car up with the issues fixed.

My next concern though is that if it has only taken 30k for a turbo to die(if it is indeed the turbo) how long will the next one last. I have treat this turbo with kid gloves - proper warm up and cool down procedures done throughout its life - maybe I should abuse this one as it might last longer.

Also does anyone know how long the new turbo will be covered for, I'm guessing it wont be for another 3 years? And should they fit a new turbo or a recon one?

Many thanks in advance.

Quote from the back of the Skoda Octavia Service Schedule:

Skoda Dealers in Europe offer a 12-month warranty on all genuine Parts from the date of installation or sale. The invoice of the Skoda Dealer should be kept for this period as proof of the date on which warranty commences.

As this is a warranty repair, and Skoda UK will be invoiced not you, I believe that the warranty on the new turbo will expire when the original 3 year warranty expires. See fordfan's related reply below to a recent similar enquiry.

hmm...so I get a 1 week warranty.:thumbdwn:

Cheers for the advice anyway mate.

Look on the bright side - you are getting a NEW turbo just as your car's warranty expires. I wouldn't mind being in your position.

True:) . I just don't want to have the fear of it going again after another 30k - hopefully its just a one off and not the remap thats boosting too much. Anyway its in now and they are working on it as I type. I'll post back with the actual fault they find.

Cheers.

Make sure you look after the turbo on this one. With it being a demo car I guess it was probably ragged straight from cold - no good for turbo longevity!

Just a thought, but if you're on good terms with the garage, ask them for an "information copy" of the invoice"?

Well I have just spoken to the 'service parts manager' at the dealer and he says the mechanic/chief tech cannot find ANYTHING wrong with the car:confused: . He says the car will make some noise as it has moving components etc etc etc. When questioned why JBS had said otherwise and why the noise was not there before he could not answer except that they were not going to do anything as they could not find a problem.

The noise definatley WAS NOT there before - its a new noise as described above - FACT

The mechanic when I first took it in admitted it was a 'strange' noise and would investigate/rectify - FACT

JBS suggested it was probably either a bearing fault or a crack on the turbo - FACT

They have basicly said as they can find no problem even though they admitted there was a noise (normal?) they can't/won't do anything a they don't deem it a problem 'noise'. When I asked if my turbo blows up a week after the warranty period it was made clear that it would be my problem not theres as it would be out of warranty then.

At this I started becomming a little irate and made a suggestion that as my warranty was almost up they are just trying to draw it out and they said that the warranty is with Skoda, not them, so they are not trying to wriggle out of it. When I said the warranty is with YOU as the car is modified and therefore against the skoda warranty making it void they said I was incorrect - skoda will warrant the car regardless of the modifications. WHAT??? News to me!

As I was getting no-where with that guy I asked to speak to the service parts manager's manager based in Sheffield who has suggested I leave it with them and get the skoda rep to have a listen, a much nicer guy tbh but I still feel I am just being passed off

PLEASE HELP as I'm unsure of what to do next - warranty is out on the 23rd March.

One seriously peed off Skoda driver here:mad:

Ok, I've taken the car to another dealer who have given me a different 'fault'.

They are saying its the 'active charcoal filter':confused:

What is this? What does it do? Should it make a sound (hasn't done so before) and should it be replaced if it is making the sounds reported above? Anyone had this problem before, if it is indeed a problem?

Any help would be greatly appreciated.
